The efficacy of different biocontrol agents, botanicals and a biorational insecticide were evaluated against whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae) in tomato under field conditions at Shivamogga, Karnataka during two seasons (Rabi 2018-2019 and summer 2019-2020). The results revealed that spiromesifen 240 SC @ 0.7 ml/L was the most effective in reducing the B. tabaci population i.e., 85.12 and 85.16 % reduction over untreated control during Rabi and summer, respectively followed by azadirachtin 5% @ 2 ml/l with reduction of 68.61 and 66.32 % over untreated control during Rabi and summer, respectively. The response of these treatments was also observed on the yield attributes, with highest fruit yield of 53.67 t/ha (6 pickings) in spiromesifen treatment followed by azadirachtin (52.93 t/ha), but the highest Benifit: Cost ratio was noticed in azadirachtin 5% (1:3.41), followed by spiromesifen 240 SC (1:3.38).Keywords

Encyrtid parasitoids play an important role in the biological control of many agricultural as well as horticultural pests. The present study determines and compares the faunal and temporal diversities of Encyrtidae in finger millet, rice and sugarcane ecosystems at the College of Agriculture, V C Farm, Mandya, Karnataka. The study was conducted at fortnightly intervals over a period of 12 months from March, 2016 to February, 2017 at the G and C-blocks of the farm. As a result, 2647 encyrtids were collected- 1019 specimens (20 genera) were from finger millet; 604 (22 genera) and 1024 (29 genera) were from rice and sugarcane ecosystems, respectively. The abundance, Shannon-Wiener index, Simpson index and richness (Margalef’s index) were computed and it was concluded that maximum diversity occurred in sugarcane and rice ecosystems (Hʹ=3.00) and the least was with the finger millet ecosystem (Hʹ=.2.78). Bray-Curtis cluster analysis and Metric Multidimensional scaling analysis were made to study the similarity and encyrtid diversity in different seasons.Keywords
