Lepidopteran assemblages were studied at 16 sampling sites in the Hajdúság Region between 2013 and 2020. Although studies targeted development of synthetic phenylacetaldehyde-based and semi-synthetic isoamyl alcohol-based baits for pest monitoring, traps caught 179 species belonging to the Sphingidae, Thyatiridae, Geometridae, Erebidae and Noctuidae families. Most species were pests or widely distributed generalists, but there were also many rare habitat specialists, for example, silvicol species, whose appearance was unexpected in the recently less forested region. The specificity of the two bait types tested differed notably both on family and subfamily levels. Semi-synthetic baits performed better and attracted a wide range of noctuids belonging mainly to the Xyleninae and Noctuinae subfamilies, while synthetic phenylacetaldehyde-based lures showed specificity to Plusiinae subfamilies with lower number of sampled species. Our data fill a gap of knowledge since the fauna studied f...

The fall armyworm, Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae), is a major pest of maize and frequently demands control measures. The timing of insecticide application is a key factor in determining its efficiency, so an experiment was designed to investigate this. Application of insecticide was based on three criteria: (i) the number of trap-caught moths in a Delta-type trap with a commercial sex pheromone lure placed in the center of the target area, soon after plant emergence; (ii) the percentage of plants exhibiting pinhole-type damage (10% or 20%) and (iii) the percentage of plants exhibiting shot hole-type damage (10% or 20%) compared to a check plot without any control measures. We found that the number of trap-caught moths was, compared to the other methods, the best means of deciding on insecticide application in maize to control the fall armyworm. Using pheromone traps, we obtained the best performance of the insecticide Spinosad, causing >90% larval mortality. Without insecticide application, maize yield reduction due to fall armyworm larva damage was 39%.

An alternative for the population suppression of Spodoptera frugiperda is the use of toxic baits. The objective of this study was to evaluate the dietary preference and toxic effect of insecticides associated with the attractiveness of S. frugiperda adults as a pest management method. The following attractions were tested: 1) 5% sucrose solution, 2) 10% sugarcane syrup, 3) 10% honey, 4) 5% hydrolyzed protein, 5) Noctovi® 43sb, 6) Noctovi® OVI PLU 1-3, 7) Noctovi® OVI PHE/PAL 50-50 in the study with choice. Attractions: 1) sugarcane syrup 10%, 2) Noctovi® 43sb, 3) Noctovi® 43sb + sugarcane syrup 10%, 4) Noctovi® OVI PLU 1-3 in the study with no chance of choice. For the toxicity study, the food attraction associated with insecticides was used: methomyl 2%, lambda-cyhalothrin 1%, chlorpyriphos 2%, spinosad 1%, chlorantraniliprole 2% and chlorfenapyr 2%. The experimental design was the completely randomized design (CRD) with chance of choice, without chance of choice and toxicity. The ...
Chemical Ecology and Management of Lobesia botrana (Lepidoptera: Tortricidae)
Journal of Economic Entomology, 2011
The moth Lobesia botrana (Denis & Schiffermü ller) (Lepidoptera: Tortricidae) feeds on grapes (Vitis vinifera L.), reducing yield and increasing susceptibility to fungal infections. L. botrana is among the most economically important insects in Europe and has recently been found in vineyards in Chile, Argentina, and California. Here, we review L. botrana biology and behavior in relation to its larval host (the grapevine) and its natural enemies. We also discuss current and future control strategies in light of our knowledge of chemical ecology, with an emphasis on the use of the sex pheromone-based strategies as an environmentally safe management approach. Pheromone-mediated mating disruption is the most promising technique available on grapes and is currently implemented on Ϸ140,000 ha in Europe. Experience from several growing areas conÞrms the importance of collaboration between research, extension, growers, and pheromone-supply companies for the successful implementation of the mating disruption technique. In the vineyards where mating disruption has been successfully applied as an areawide strategy, the reduction in insecticide use has improved the quality of life for growers, consumers, as well as the public living near wine-growing areas and has thereby reduced the conßict between agricultural and urban communities.
FIELD TRIALS WITH PHEROMONE TRAPS ON MAJOR LEPIDOPTEROUS INSECT PESTS OF FIVE VEGETABLE CROPS
Field trials were conducted in farmers' fields at Rajanukunte, Bengaluru North and Narasapura, Kolar (Karnataka, South India) to test the efficacy of pheromone traps against five lepidopterous pests of vegetables during kharif and rabi, 2007. The red traps were the most effective in trapping male moths of Helicoverpa armigera (Hub.) (11.89 ± 7.99 moths/trap/week), Earias insulana (Boisd.) (4.39 ± 2.27 moths/trap/week) and diamondback moth (DBM), Plutella xylostella (Linn.) (13.23 ± 11.10 moths/trap/ week). The red (19.68 ± 12.49 moths/trap/week) and pink (18.76 ± 11.60 moths/trap/week) traps were found to be on par in trapping the male moths of brinjal shoot and fruit borer (BSFB), Leucinodes orbonalis Guen. Yellow pheromone traps attracted maximum moths of Spodoptera litura Fab. (22.01 ± 14.61moths/trap/week). However, differences in numbers of moths trapped were statistically non significant. When the most effective, red traps for five pest species were field tested at two locations, Rajanukunte and Narasapura for conformity, Narasapura recorded the maximum H. armigera (7.88 ± 3.89 moths/trap/week) and S. litura moths (40.50 ± 16.78 moths/trap/week). Whereas E. insulana (4.28 ± 2.52 moths/trap/week) and DBM (12 ± 10.42 moths/trap/week) moths were recorded in higher number at Rajanukunte. The moth catches of BSFB were found to be on par at both the locations. Laboratory evaluation of lures placed in red, pink and yellow traps showed that lures in red traps were the most attractive to the male moths of the five pest species. The study concludes that beside other factors, trap colour also plays an important role in attracting moths of these five lepidopterous pest species.

Traps baited with 4 different commercial sex pheromone lures that contained 2, 3, or 4 components were used to capture male fall armyworm [Spodoptera frugiperda (J. E. Smith)] in Alabama, Georgia, Florida, and Texas from 2006-2009. A subset of the moths collected was analyzed for their host strain to determine if there was a difference in attraction to these lures. Chemical analysis of the lures was completed to identify the pheromone components released. Each lure released the number of components expected, but the Trécé lure released relatively higher amounts of the minor component Z7-12:Ac and at a higher percentage of its blend, than the other lures. The 4 lures attracted similar numbers of moths in Alabama, Georgia, and Texas, and there was only a difference among lures in the Florida 2006 trial. More moths were captured in fall 2007 than fall 2008 in Alabama and Georgia. The southern region in Alabama and Georgia averaged more than 13 moths per night, compared to 8.5 in the central region, and 1.9 in the northern region. Lures attracted both host strains of moths, but across years and locations (n = 4546), all lures attracted more corn strain than rice strain males (>55% of moths analyzed were corn strain). However, traps baited with Trécé lures captured a 5% lower percentage of corn strain moths than Scenturion-baited lures. Geographic location and time of season appeared to be much more important in determining host strain identity than the specific commercial lure used. Results from these trials suggest that any of the commercial lures tested will attract the numbers of fall armyworm moths necessary for genetic and migration analysis, and that site location (away from trees and in open areas) and periodic trap maintenance (removal of spiders and frogs from clogging the funnel or eating trap catch) are also important in capturing the highest number of moths.

A 2-year study conducted in 0.6-ha apple (Malus domestica Borkh.) blocks examined the effects of treatment with pheromone rope dispensers on captures of the obliquebanded leafroller, Choristoneura rosaceana (Harris, 1841), and the redbanded leafroller, Argyrotaenia velutinana (Walker, 1863), in traps baited with varying dosages of pheromone lures or Isomate ® -OBLR/PLR Plus pheromone rope dispensers. In untreated blocks, captures of male A. velutinana were high and did not differ among (i) traps baited with a standard lure loading used to monitor this pest, (ii) lure loadings 10 and 100 times the standard loading, and (iii) traps baited with an Isomate-OBLR/PLR Plus pheromone rope dispenser. In pheromone-treated blocks, captures of A. velutinana in traps were reduced 94%-99% for all loadings tested (up to 1000 times the standard loading). The results for C. rosaceana were different. In untreated blocks in 2002, traps baited with 10 or 30 standard lures captured significantly more C. rosaceana than traps baited with a single standard lure; however, in 2003, traps baited with the standard lure loading captured significantly more moths than traps baited with 100 and 1000 times the standard loading. Also, traps baited with Isomate-OBLR/PLR Plus pheromone rope dispensers captured significantly fewer C. rosaceana than traps with standard lures in untreated blocks. In pheromone-treated blocks, traps baited with standard monitoring lures and lures with higher loadings (10 and 1000 times the standard) captured equivalent numbers of C. rosaceana; the capture of moths was reduced by only 50%-71%. We conclude that Isomate-OBLR/PLR Plus pheromone rope dispensers deployed in Michigan, United States of America, are effective in disrupting orientation of A. velutinana; however, they are not very effective for C. rosaceana. In addition, increasing lure loading above that of 1× monitoring lures (rubber septa or membrane type) does not appear to reliably increase the effectiveness of monitoring of males of either leafroller species in orchards where pheromone ropes are deployed at recommended densities.
