|
The effects of oral application of fenoxycarb, the commercial formulation Insegar, To the selected developmental stages of the silkworm, Bombyx mori, was investigated. An oral application of chemical to the silkworm from the 2nd- to the 5th-instar larvae delayed the larval development upto more than 40 days and increased the larval body weight in the range of 1.1 to 1.7 folds. When the chemical was orally applied to the final instar larvae, spinning and pupation were prevented, and consequently permanent larvae occurred, The weight of a cocoon and its shell of silkworm(Bombyx, mori, L) increased follwing the application of fenoxycarb to the 2nd- and the 3rd- larvae.
