| dc.description.abstract | An experiment was carried out in the Department of Sericulture, UAS, GKVK, Bengaluru during 2020-2021 to assess the chemicals with insecticidal and acaricidal property on safety of silkworms, Bombyx mori L. Among the pesticides evaluated, abamectin along with diafenthiuron performed better than the rest of the pesticides but were on par with the standard checks [wettable sulphur 80 % WP @ 2.5 g/l and dimethoate 30 % EC @ 2 ml/l]. Fenpropathrin 30 % EC @ 0.3 ml/l did not perform well in mulberry as well as rearing performance of silkworms at both 15 and 20 DAS. Abamectin and diafenthiuron did not exhibit any visual phytotoxic symptoms on mulberry and also did not affect the population of natural enemies which resulted in increased leaf yield at both 25 and 30 DAP spray schedule. When the treated leaves from these two pesticides were fed to the silkworms, it was found safer to the worms as they recorded zero mortality and cent per cent larval progression were observed at 15 and 20 DAS. Better rearing [shortest larval duration, maximum larval weight, ERR (%)] and reeling [cocooning percentage, cocoon weight, cocoon shell weight, longest filament length and maximum filament weight] performances were observed at 20 DAS when compared to 15 DAS. Hence, abamectin 1.9 % EC @ 0.75 ml/l and diafenthiuron 50 % WP @ 1 g/l can be verified as an alternate molecule to DDVP for managing both mulberry thrips and mites, where they found safer to the silkworms at 20 DAS. | en_US |
