Investigations were carried out on monitoring of melon fruit fly, Zeugodacus cucurbitae Coquillett on bitter gourd (Momordica charantia L.) using para-pheromone traps during Kharif, 2018-19 at CCS HAU, Hisar. The incidence of Z. cucurbitae started gradually and increased from 31st to 42nd Standard Meteorological Week (SMW) corresponding to the 1st week of September to 3rd week of October. Higher number of fruit flies (on average 9.5 to 40.5 flies/trap) were recorded in the month of September to first fortnight of October with a peak of 40.5 flies/trap during 37th SMW. Correlation analysis with various weather parameters indicated that maximum temperature (r = 0.611*), morning relative humidity (0.590*) and rainfall (0.747**) had significant positive correlation with trap catch population of melon fruit fly. The present findings also revealed that the influence of all-weather parameters was high and significant on trap catches population of the adult male melon fruit fly (R2=0.76).
A detailed survey was carried out to record the insecticide usage pattern in brinjal and knowledge level of farmers on insecticides handling to control brinjal shoot and fruit borer, Leucinodes orbonalis from brinjal growing farmers of Shivamogga (Karnataka), Coimbatore (Tamil Nadu), Tirupati and Vijayawada (Andhra Pradesh), Pune (Maharashtra) and Gadwal (Telangana) Districts of India during 2020-21. The information on insecticide usage pattern was gathered from twenty progressive farmers from each selected location using well-structured questionnaire. The data revealed that farmers used eighteen different insecticides to manage L. orbonalis in brinjal. Among the different insecticides the highest usage of chlorantraniliprole 18.5 SC (70%) was reported followed by emamectin benzoate (55%) and lambda-cyhalothrin (33.33%). The number of application of insecticides in the six locations varied from 10.8 to 22.20 per cropping season at an interval ranging from 7.0 to 12.4 days. In order to get information on insecticide recommendation, 48.33 per cent of brinjal farmers approached pesticide dealer shops and 78.33 per cent farmers did not pay attention towards label information given in pesticide containers. In different localities, around 51.67 per cent of farmers sprayed insecticides at recommended dose and nearly 71.67 per cent of farmers did not follow any safety measures while undertaking spraying operation. In all the locations (83.33%) farmers relied only on Insecticides and only around 10.0 per cent famers followed cultural control methods for L. orbonalis control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
