Feeding larvae with abamectin-treated leaves improves cocoon weight and filament characteristics in Bombyx mori, suggesting effective pest management.
Chemical sprays have become an essential component of modern pest management strategies in agriculture. However, silkworms (Bombyx mori L.) are highly sensitive to chemical residues, necessitating extensive research to identify compounds that are both effective against pests and safe for silkworm rearing. In this context, the present study was undertaken to assess the impact of feeding mulberry leaves sprayed with abamectin 1.9% EC on the cocoon and filament traits of B. mori. The results of the study revealed that larvae fed with abamectin 1.9% EC sprayed leaves at 20 days after spray (DAS) recorded highest cocoon weight (1.59 g), shell weight (0.325 g), cocoon shell ratio (19.98%), Average filament length (1038.49 m), non-breakable filament length (1001.57 m), filament weight (0.298 g) and denier (2.52).
