To select the appropriate biological control agent for a target pest, an understanding of the demographic parameters is essential. Therefore, a study was conducted to determine the effect of five temperatures, 12, 17, 22, 27, and 32°C, at 60% RH and 5.0 Lux photoperiod of 16:8 (L:D) h, on the parasitism rate, development, and fecundity of these three parasitoids of Aphis gossypii Glover (Hemiptera: Aphididae). Only L. fabarum parasitized at 12°C and the rate was low. None of the parasitoids was able to develop at 32°C. Lysiphlebus testaceipes had the shortest developmental period at the other temperatures. Lysiphlebus confusus and L. fabarum had similar developmental times at 22 and 27°C, with L. confusus completing its development faster at 17°C. The mortality rate of the three parasitoids varied between 3 and 20% at 17, 22, and 27°C, except for L. testaceipes which had about 53% mortality at 27°C. Lysiphlebus testaceipes had the highest net reproductive rate at all temperatures for the 2.5 and 97.5% bootstrap CIs. Lysiphlebus fabarum had the highest intrinsic rate of increase at 22°C and L. testaceipes had the highest at the other temperatures. The best temperatures for fecundity were 17 and 22°C for L. testaceipes and 22°C for the other species. Lysiphlebus testaceipes appeared to be the most suited biological control agent for A. gossypii in southern Turkey, but its intolerance to high temperature could prove problematic for its establishment and persistence in this region.

(Heteroptera: Scutelleridae) is the most important harmful insect of wheat in Turkey. Within the Gramineae family, Sunn pest feeds and makes damage especially in different phenological periods of wheat. It has been indicated that natural enemies have a great effect on the factors suppressing the sunn pest. The most important ones of these natural enemies are the species included in the Scelione family of Hymenoptera. There exist site-specific secondary species apart from the common species suppressing the sunn pest populations. Their spreading and availability rates are relatively lower, but they are important in some regions and years. At the results of some studies, it has been seen that Gryon monspelensis (Picard) (Hymenoptera: Scelionidae) is occasionally effective on the eggs of sunn pest in some regions of Gaziantep Province. The effects of application dosages of today's most commonly used 4 insecticides (Alpha-cy...

Predatörler, parazitoitler ve bunların avlarını ve konukçularını barındıran bitki örtüsü insan faaliyetleri tarafından tahrip edilebilir. Bu nedenle, turunçgil ekosisteminin florası, yararlı böceklerin yanı sıra bu böceklerin üzerinde yaşıyacağı bitki türlerini de göz önünde bulundurarak yönetilmelidir. Bu bağlamda, araştırmanın amacı, turunçgil ağaçlarındaki yaprakbiti popülasyonunu baskı altına almak için doğal düşmanlara kışlak sağlanarak bunların etkinliklerini arttırmaktır. Çalışma, Kasım 2006-Mayıs 2007 ve Kasım 2007-Mayıs 2008 tarihlerinde iki farklı 10 dekarlık genç turunçgilbahçesinde (Alata-Mersin ve Kayarlı-Adana) yürütülmüştür. Bu amaçla, denemeler 6 farklı yem veya baklagil bitkisi ve bir kontrol parseli olmak üzere 7 parselde gerçekleştirilmiştir.Ekilen bitki türleri, bakla, bakla + fiğ, bakla + fiğ + tritikale, tritikale + fiğ, tritikale + yonca ve tritikale + üçgül'dür.Denemeler, dört tekrarlı tesadüf blokları deneme desenine uygun olarak kurulmuştur. Ekilen bitki çeşitlerine ait tohumların çimlenmesinden sonra yaprak bitleri ve yararlı böcekleri saymak için bahçeler her hafta kontrol edilmiştir.Turunçgilde Aphis craccivora, Aphis spiraecola ve Aphis gossypii çok sık görülen yaprakbiti türleri olmasına rağmen, Aphis craccivora, Aphis fabae ve buğday yaprak bitleri, farklı yem bitkileri veya baklagiller bitkilerinde yaygın yaprakbiti türleri olarak tespit edilmiştir.Aphis craccivora, Erdemli-Mersin bölgesindeki turunçgil ağaçları için yaygın bir yaprakbiti olmamasına rağmen, deneme bahçesindeki en yüksek popülasyonu oluşturan yaprakbiti türü olmuştur.Coccinella septempunctata, baklagiller ve tritikale ait bitkiler üzerinde yaygın bir predatör türü iken, Scymnus spp. turunçgil üzerinde çok sık rastlanan türlerden olmuşturThe conservation of natural enemies is one of the main steps in a successful biological control program. Weed flora that harbors predators, parasitoids and also their prey and hosts can be destroyed by human activities. Therefore, the flora of the citrus ecosystem should be managed in a way that supports not only beneficial insects but also the unwanted weed species. In this respect, the aim of this study was to provide winter harbors and prey sources for entomophagous insects in order to control aphid populations on citrus trees. The study was carried out in two young, 1 ha citrus orchards in Alata-Mersin and Kayarlı-Adana between November 2006 and May 2007, and November 2007 and May 2008. The experiment was performed on 6 different grasses and leguminous plants and unplanted control plots. The seeded plant varieties were broad bean, broad bean+common vetch, broad bean+common vetch+triticale, triticale+common vetch, triticale+clover and triticale+trifolium. The experiment was established in a randomized complete block design with four replications. The experimental plots were visited weekly to count aphids and beneficial insects following germination. Although Aphis craccivora, Aphis spiraecola and Aphis gossypii were the most commonly seen aphid species on citrus, Aphis craacivora, Aphis fabae and wheat aphids were the most abundant species on different grass or leguminous plants. Though Aphis craccivora was not a common aphid species on citrus trees in Erdemli-Mersin region, due to its high population in the experimental plots made it the most important aphid species on the citrus trees. Aphis craccivora was the most common aphid species on the citrus trees in both orchards. Coccinella septempunctata was a common predator on leguminous and triticale plants, while Scymnus sp. was one of the most abundant predator on citrus trees in both location

Results revealed that A. aurantii exhibited 3 generations in the spring, summer, and autumn each year for 2004 and 2005. The highest population density of second-stage larvae occurred on leaves at densities of 18 and 46 individuals per 4 cm2 with the lowest density occurring on stems at levels of 7 and 8 individuals per cm2 in grapefruit in both years. Parasitoid populations increased in the summer and into autumn. Parasitation rate was increased by releasing A. melinus adults in the orchards. In 2004 and 2005, respectively, the highest parasitization rate occurred on infested leaves with 60.8% and 40.8%, followed by infested fruits at 25% and 54.5%, on infested shoots with 36.4% and 19.3%, ...

Helicoverpa armigera has five generations in a year, but only three attack cotton in the East Mediterranean region of Turkey. Releases of T. evanescens are made twice against each of the first three generations of H. armigera in the years of 2004-2005. In each release, 120,000 parasitoids ha 21 were released, resulting in 62.9% and 71.6% parasitism and the numbers of larvae of H. armigera were reduced by 76.8% and 80.6%, respectively. In fields where insecticides were applied, the numbers of larvae of H. armigera were reduced by 57.1% and 77.1%, respectively. Furthermore, it was observed that population of natural enemies was increased in released parasitoid plots, with an average of 33 to 39 Chrysoperla carnea (Steph.) (Neuroptera:Chrysopidae) were encountered in 25 plants. Pollengenerating plants (maize, okra, weeds, etc.) probably increased the density of the predator. The cultivation of okra as a trap plant can be recommended especially in cotton fields where parasitoid release was conducted. The results of biological control of the noctuid H. armigera by T. evanescens appear promising.

This injury is induced by apterous aphid groups, however alate groups can cause other economically important problems such as virus transmission. Apterous population of aphids are controlled by cultural, biological or chemical control methods. Flight activity of alate populations are much difficult to control because a short time, like a minute or half an hour, is enough for single individuals to transmit viral diseases. The first and most critical step in monitoring alate aphid population is to use the right integrated pest management strategies (IPM). The present study was carried out in Department of Plant Protection Experimental Station of Çukurova University between October 2009 to October 2010 in order to understand the dispersal time of aphid and right sampling methods of alate individuals. Approximately 400 citrus plants were planted spaced of 5.0 m × 3.0 m apart in the orchard in September...

Chamaemyiidae is a small family of predaceous flies, including aphidophagous and coccidophagous species. Little is known about their ecology, and partial failures of Chamaemyiidae-based biological control programs against aphids may be due to poor synchronization of predator-prey seasonal habits. In this study, we investigated seasonality of predation and prey range of aphidophagous Chamaemyiidae. A field survey was conducted on crops and indigenous flora in seven agricultural sites in southern Turkey. Seventeen host plant families were surveyed for Chamaemyiidae presence and 371 silver flies were studied. All Chamaemyiidae larvae were observed to prey on adult and young instar aphids in the field. Silver fl...

Chemical control is the often preferred method in controlling these pests. Use of pesticides have generally resulted in pesticide resistance and eliminating natural enemies. Exochomus nigromaculatus is a predatory insect of globose scale and other scale insects. Inappropriate use of pesticides has been linked with adverse effects on non-target organisms (e.g., reduction of beneficial species populations and increase of pest populations). This study evaluated the side effects of five insecticides (Acetamiprid, deltamethrin, spirotetramat, sulfoxaflor, dimethoate) and a plant extract (orange oil) on immature stages of E. nigromaculatus using dry film method. Acetamiprid and deltamethrin caused the highest mortality rate (97.3%) besides standard toxic dimethoate. Sulfoxaflor accounted for approximately 70% mortality to E. nigromaculatus. In contrast, spirotetramat and orange oil caused less than 20% mortality to the predat...

Main whitefly species problematic in the greenhouses, where tomatoes grown primarily, is Bemisia tabaci Genn. (Hemiptera: Aleyrodidae) in Mediterranean Region of Turkey. Serangium parcesetosum Sicard (Coleoptera: Coccinellidae) is proved as a coccinellid predator of B. tabaci and a voracious feeder by several studies. The hypothesis "the outcome of a biological control program is determined by the initial pest to predator ratio" was examined on caged tomato in greenhouses. The current study showed the influence of initial whitefly density on the whitefly population growth rate, which was independent of the absence or presence of S. parcesetosum (P> 0.05) for the whitefly density × predator release interaction). No significant differences in whitefly suppression from S. parcesetosum predation were monitored between the two initial whitefly densities in both years. The density of the pest was reduced by S. parcesetosum in high and moderate initial whitefly density cages 2-3 weeks after releasing the ladybird beetles. During the experiment, copulating adults, larvae, and pupae of the predatory ladybird beetle were observed in both predator-releasing cages. These results indicated that S. parcesetosum can survive and reproduce on tomato plants in greenhouse production during the spring months in Mediterraenean region of Turkey.

A long-term survey revealed that Capsella bursa-pastoris is a significant host plant, especially for aphids as well as their parasitoids and hyperparasitoids. Twenty-five aphids and eleven parasitoid species were identified on this weed. Myzus persicae and Aphis gossypii were the most commonly recorded aphid species, and Binodoxys angelicae the most frequent parasitoid. Additionally, the monthly distribution of the aphids, parasitoids, and hyperparasitoids showed that C. bursa pastoris fills the host plant gap in the absence of crops. Trophic relations within the community and the importance of C. bursa pastoris were also analyzed in this study. Abstract The reproduction of aphids depends to a great extent on their host plants, an integration that impacts on the successful expansion of overwintering populations. Therefore, a survey was conducted to evaluate the globally distribut...

Helicoverpa armigera has five generations in a year, but only three attack cotton in the East Mediterranean region of Turkey. Releases of T. evanescens are made twice against each of the first three generations of H. armigera in the years of 2004-2005. In each release, 120,000 parasitoids ha 21 were released, resulting in 62.9% and 71.6% parasitism and the numbers of larvae of H. armigera were reduced by 76.8% and 80.6%, respectively. In fields where insecticides were applied, the numbers of larvae of H. armigera were reduced by 57.1% and 77.1%, respectively. Furthermore, it was observed that population of natural enemies was increased in released parasitoid plots, with an average of 33 to 39 Chrysoperla carnea (Steph.) (Neuroptera:Chrysopidae) were encountered in 25 plants. Pollengenerating plants (maize, okra, weeds, etc.) probably increased the density of the predator. The cultivation of okra as a trap plant can be recommended especially in cotton fields where parasitoid release was conducted. The results of biological control of the noctuid H. armigera by T. evanescens appear promising.

This injury is induced by apterous aphid groups, however alate groups can cause other economically important problems such as virus transmission. Apterous population of aphids are controlled by cultural, biological or chemical control methods. Flight activity of alate populations are much difficult to control because a short time, like a minute or half an hour, is enough for single individuals to transmit viral diseases. The first and most critical step in monitoring alate aphid population is to use the right integrated pest management strategies (IPM). The present study was carried out in Department of Plant Protection Experimental Station of Çukurova University between October 2009 to October 2010 in order to understand the dispersal time of aphid and right sampling methods of alate individuals. Approximately 400 citrus plants were planted spaced of 5.0 m × 3.0 m apart in the orchard in September...

Chamaemyiidae is a small family of predaceous flies, including aphidophagous and coccidophagous species. Little is known about their ecology, and partial failures of Chamaemyiidae-based biological control programs against aphids may be due to poor synchronization of predator-prey seasonal habits. In this study, we investigated seasonality of predation and prey range of aphidophagous Chamaemyiidae. A field survey was conducted on crops and indigenous flora in seven agricultural sites in southern Turkey. Seventeen host plant families were surveyed for Chamaemyiidae presence and 371 silver flies were studied. All Chamaemyiidae larvae were observed to prey on adult and young instar aphids in the field. Silver fl...

Chemical control is the often preferred method in controlling these pests. Use of pesticides have generally resulted in pesticide resistance and eliminating natural enemies. Exochomus nigromaculatus is a predatory insect of globose scale and other scale insects. Inappropriate use of pesticides has been linked with adverse effects on non-target organisms (e.g., reduction of beneficial species populations and increase of pest populations). This study evaluated the side effects of five insecticides (Acetamiprid, deltamethrin, spirotetramat, sulfoxaflor, dimethoate) and a plant extract (orange oil) on immature stages of E. nigromaculatus using dry film method. Acetamiprid and deltamethrin caused the highest mortality rate (97.3%) besides standard toxic dimethoate. Sulfoxaflor accounted for approximately 70% mortality to E. nigromaculatus. In contrast, spirotetramat and orange oil caused less than 20% mortality to the predat...

Main whitefly species problematic in the greenhouses, where tomatoes grown primarily, is Bemisia tabaci Genn. (Hemiptera: Aleyrodidae) in Mediterranean Region of Turkey. Serangium parcesetosum Sicard (Coleoptera: Coccinellidae) is proved as a coccinellid predator of B. tabaci and a voracious feeder by several studies. The hypothesis "the outcome of a biological control program is determined by the initial pest to predator ratio" was examined on caged tomato in greenhouses. The current study showed the influence of initial whitefly density on the whitefly population growth rate, which was independent of the absence or presence of S. parcesetosum (P> 0.05) for the whitefly density × predator release interaction). No significant differences in whitefly suppression from S. parcesetosum predation were monitored between the two initial whitefly densities in both years. The density of the pest was reduced by S. parcesetosum in high and moderate initial whitefly density cages 2-3 weeks after releasing the ladybird beetles. During the experiment, copulating adults, larvae, and pupae of the predatory ladybird beetle were observed in both predator-releasing cages. These results indicated that S. parcesetosum can survive and reproduce on tomato plants in greenhouse production during the spring months in Mediterraenean region of Turkey.

A long-term survey revealed that Capsella bursa-pastoris is a significant host plant, especially for aphids as well as their parasitoids and hyperparasitoids. Twenty-five aphids and eleven parasitoid species were identified on this weed. Myzus persicae and Aphis gossypii were the most commonly recorded aphid species, and Binodoxys angelicae the most frequent parasitoid. Additionally, the monthly distribution of the aphids, parasitoids, and hyperparasitoids showed that C. bursa pastoris fills the host plant gap in the absence of crops. Trophic relations within the community and the importance of C. bursa pastoris were also analyzed in this study. Abstract The reproduction of aphids depends to a great extent on their host plants, an integration that impacts on the successful expansion of overwintering populations. Therefore, a survey was conducted to evaluate the globally distribut...
