Abstract

The present investigations on Holistiand#1010; approaand#1010;hes for the management of the invasive pest, tomato pinworm, Tuta aand#389;soluta (Meyriand#1010;k) in tomato under proteand#1010;ted and#1010;ultivation were conducted at Horticultural Farm, Rajasthan College of Agriculture, Udaipur during Rabi 2020 and 2021 and the laboratory work was done in the Department of Entomology, Rajasthan College of Agriculture, Udaipur and in the Molecular Genetics Faculty of Aquaculture Research unit, DOR, MPUAT, Udaipur. newlineThe maximum number of eggs, larvae, mines, leaf infestation of T. absoluta newlinewere recorded as 21.73 and 22.33; 17.63 and 17.70; 17.70 and 17.87; 71.93 and 78.53; newline96.40 and 97.93 per plant during third week and last week of March 2020 and 2021. The fruit infestations of T. absoluta was recorded as 96.40 and 97.93/plant during 2020 and 2021. Maximum population of S. litura was noticed during the 1st week of March (0.60 and 0.63 larvae/plant) H. armigera maximum population were noticed 1.25 larvae/plant during the 1st week of March 2020 and 1.20 larvae/plant 4th week of February 2021. Maximum aphid population were noticed during the 3rd week of February (24.50 and 26.00 adult/plant); and likewise, whiteflies were noticed during the 3rd week of February (31.00 and 34.00). newlineThe natural enemies of T. absoluta such as mirid bugs and coccinellids were observed on the tomato during both the years. The peak population of mirid bugs (1.40 and 1.43 adults/plant) was recorded during the 2nd week of March. Similarly, the monitoring of coccinellid populations showed that the peak activity was during the 2nd week of March (1.28 and 1.31 adult/plant, respectively) during the respective seasons newline
