Abundance of insect pests associated with brinjal (Solanum melongena L.) crop
Akinik publication, 2019
The present investigation entitled “Study on abundance of Insect Pests associated with Brinjal (Solanum melongena L.) Crop” was carried out in randomized block design with three replication at Crop Research Center of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut during kharif 2017. During the crop season 10 insect species, belonging to four orders and 9 families: Lepidopterans with Leucinodes orbonalis, Eublemma olivacea, and Euzophera pertcella, Hemipterans with Amrasca biguttula biguttula, Bemisia tabaci, Urentius histericellus and Aphis gossypii, Orthoptera with Melanoplus differentialis and Coleopterans with Trachys herilla and Henosapilachna vigintioctopuncata were found attacking the brinjal crop from vegetative to reproductive stage. Among them jassid (Amrasca biguttula biguttula Ishida), whitefly (Bemisia tabaci Gennadius), jassid (Amrasca biguttula biguttula Ishida) and fruit borer (Leucinodes orbonalis Guenee) were recorded as major pests. Other insects pests recorded on the crop were of less importance and less damage caused by them was found without much economic loss.
EVALUATION OF SEASONAL INCIDENCE OF MAJOR BRINJAL PESTS
Brinjal (Solanum melongena L.; Solanacae) known also as " egg plant " or " Aubergine " , is one of the important vegetable crops of India. The insect pests like Shoot and Fruit borer, Epilachna beetle, Whitefly and Mealybug are considered major. Evaluation of the seasonal incidence of these pests helps in understanding the population fluctuation of these pests and therefore their effective management. A field survey was carried out at weekly interval in two different locations during January 2016 and 2017. The percent shoot damage caused by Brinjal shoot and fruit borer increased slowly till 10 th standard week and then started to decline. Similarly, the fruit damage also increased till 12 th standard week and then started to decline. The average number of Epilachna grubs per plant indicated their abundance starting from sixth standard week till 14 th standard week. The damage decreased with decreasing number of grubs. The population of white flies started to increase during the mid season of the crop (8 th standard week) and continued in an increasing trend till 16 th standard week. The mealy bug incidence was totally absent till sixth standard week and started to increase thereafter. However, the peak incidence was reported only in the late season crop starting from 13 th standard week. Correlation with weather parameters revealed their influence of population fluctuation.
Study on the succession of insect pests of brinjal
During the studies on the insect pests succession revealed that a total of eight insect species were found associated with brinjal crop at different crop growth stages. The first attack on the crop appeared in the one week after transplantation and continued up to till crop harvested. Pests were found attacking on the crop were jassids (Amrasca biguttula biguttula), aphids(Aphis gossypii), white fly (Bemisia tabaci), leaf roller (Eublemma olivacae), shoot and fruit borer (Leucinodes orbonalis), epilachna beetle (Epilachna vigintioctopunctata), leaf webber (Psara bipunctalis) and grass hopper(Chrotogonus spp.). Among them, brinjal shoot and fruit borer (L. orbonalis) was recorded as major pest. Jassids (A. biguttula biguttula Ishida), aphid (A. gossypii Glov.) and epilachna beetle (E. viginitioctopunctata F.) were found to damage the crop moderately. Other insects pests recorded on the crop were of less importance and extent of damage caused by them was found without much economic loss.
Overview of Brinjal (Solanum melongena L.) Pests and Their Management: A Review
Archives of Current Research International, 2024
Brinjal (eggplant or aubergine), a widely cultivated vegetable in tropical and subtropical regions, faces significant threats from a variety of insect pests. These pests cause substantial damage at different stages of crop growth, leading to reduced yields and compromised fruit quality. This review provides a comprehensive overview on the major insect pests that affect brinjal cultivation, focusing on their biology, damage mechanisms, and current management practices. Special emphasis is placed on integrated pest management (IPM) strategies, combining cultural, biological and chemical control methods to promote sustainable brinjal production.
This study investigated the relative performance of ten brinjal (Solamum melongena L.) varieties for yield in fall 2014 in Bahawalpur. The study was conducted at farm area of Islamia University of Bahawalpur. Ten brinjal varieties were evaluated for yield performance in a research trial following randomized complete block design. Significant differences existed in the yield generated by tested varieties. Significantly more yield was recorded in Shamli and Eggplant deep black followed by Advanta 306, Sandhya F1, Black boy, Black nagina and Advanta 305 in descending order. Twinkle star and Kalash F1 generated significantly less yield while the significantly least yield was recorded for Xingchangjishi than all the tested varieties. Whitefly Bemesia tabaci (Homoptera: Aleyrodidae) and jassid Amrasca biguttula biguttula (Homoptera: Cicadellidae) were the major sucking insects attacking this crop. Populations of both pest insects were recorded significantly more on Xingchangjishi while least populations of these pests were recorded on Egg plant deep black and Sandhya F1. Correlation of insect populations with yield showed inverse relationships. These results are important regarding varietal performance for yield test conducted for ten brinjal varieties. Varieties i.e., Eggplant deep black and Shamli with significantly more yields are recommended for cultivation in this area to get more brinjal yield.
Host Preference, Mode of Damage and Succession of Major Insect Pests of Brinjal
Annual Research & Review in Biology
Brinjal is one of the most popular solanaceous vegetables worldwide because of its nutritive and nutraceutical values. In recent decades, brinjal cultivation has been experiencing increased biotic and abiotic stresses due to the climate changes, which had affected the cultivation practices, growers’ profit and consumers’ choice to a larger extent. Amongst different insect pests, brinjal shoot and fruit borer (BSFB) is the major one causing significant reduction in economic yield followed by epilachna beetle, aphid, jassid and whitefly. On the other hand, proper knowledge on nature of damage, host preference, and seasonal abundance of insect pests is a pre-requisite for development and deployment of an appropriate, effective and timely management strategy against the pests. A pool of literatures on host preferences, damage pattern and succession of major insect pests of brinjal has been reviewed and presented in this paper.

Aphis gossypii Glover (Homoptera, Aphididae), Amrasca biguttula biguttula (Ishida) (Hemiptera, Cicadellidae) and Leocinodes orbonalis Guenee (Lepidoptera, Pyralidae) are serious pests of S. melongena in Pakistan. Using host plant resistance can be safe and cheap alternative to insecticidal control of insect pests of S. melongena. The present study was conducted at the New Developmental Farm (NDF) of The University of Agriculture, Peshawar (UAP) in 2014. Three Brinjal genotypes Shamli, pearl long and black beauty were used in the study. Pest infestation started in the first week of May. Overall mean density of A. gossypii was non-significantly higher (0.71 individuals leaf -1 ) on Black Beauty and lower (0.66 A. gossypii leaf -1 ) on Pearl Long. Overall mean density of A. biguttula biguttula was non-significantly higher (each 0.47 individuals leaf -1 ) on Shamli and Black Beauty and lower (0.44 individuals leaf -1 ) on Pearl Long. Fruit infestation by L. orbonalis was significantly l...
