Bioactivity of Aloe vera Oil on the Weight and Length of Larvae of Silkworm (Bombyx mori Linn.)

The application of essential oil on the Bombyx mori larvae has been proved to be in sericulture industry. The experiments were conducted with different amount of Aloe vera oil viz. 0.25, 0.50, 0.75 and 1.00 ml with respect to the treatment of III , IV and V instar B. mori larvae. Three set of experiment were rd th th designed as single, double and triple treatment of larvae. The maximum larval weight (1.807±0.094 g) and larval length (6.728±0.567cm) was observed in case of triple treatment with 0.75 ml Aloe vera oil. Minimum larval weight (1.236±0.004 g) and larval length (2.845±0.153 cm) was noticed to be in case of triple treatment with 1.00 ml A. vera oil. The present study reveals that the application of essential oil (A. vera) may be useful for the production of good cocoons at commercial scale.
