Five insecticides viz., dimethoate, indoxacarb, flubendiamide, spinosad and fenazaquin were evaluated for their toxicity against beetles of Brahmina coriacea (Hope) using leaf dip and topical application methods. In leaf dip method, LC50 values of these were 8.41, 165.20, 186.66, 246.09 and 460.60 ppm, respectively, while LC90 values were 45.07, 143.71, 1749.55, 1541.82 and 2687.70 respectively. The order of toxicity was dimethoate> indoxacarb> flubendiamide> spinosad> fenazaquin. In topical application method, LC50 values were 69.71, 201.90, 415.42, 474.66 and 492.19 ppm, respectively; and LC90 values were 300.30, 1077.32, 2121.14, 2672.20 and 3083.64 ppm, respectively. The order of toxicity was indoxacarb> dimethoate> flubendiamide> fenazaquin> spinosad. Irrespective of insecticides, leaf dip method of bioassay proved more effective (except indoxacarb).Keywords

Population dynamics of rice black beetle Heteronychus lioderes Redtenbacher was studied deploying light trap, pit method and assessment of tiller infestation. The pest was observed to be active from 29th to 42nd standard week (SW) with peak being in 35th SW as shown with light trap catches. The incidence started from 29th SW and reached a peak during 31st SW (3.8 adults in five pits and 48.4% tiller infestation). The weather factors when correlated with incidence revealed significant positive correlation with rainfall, minimum and maximum temperature, whereas it was non-significant positive one with relative humidity.Keywords

Behavioral studies of honey bees are very important to promote pollination. Foraging speed and rate are such vital behavioral patterns. This study evaluates the foraging attributes of honey bees on Brassica with experiments done at different sites chosen in Kangra district of Himachal Pradesh. Apis mellifera is observed to show a significantly maximum foraging rate of 13.25 and 13.89 flowers/ min on toria and mustard, respectively. Whereas, the foraging speed was maximum for A. cerana (5.20 sec/ flower) on toria and A. mellifera (4.42 sec/ flower) on mustard.Keywords

Six insecticides were evaluated with Brahmina coriacea (Hope) for their effect on oviposition. Of these chlorantraniliprole was found to be highly effective. The order of toxicity was chlorantraniliprole> bifenthrin> clothianidin> thiamethoxam> chlorpyriphos> imidacloprid. All insecticides at low doses (1.20- 0.15x 10-4 g a.i./ kg soil) induced reduction in oviposition and it was dose dependent. The number of eggs laid ranged from 28.4- 44.8/ 3 females- maximum reduction being with bifenthrin (82.06%), followed by chlorpyriphos (79.28%).Keywords
