Abstract

Plant products are capable of producing multiple effects in insects such as antifeedancy, growth regulation, fecundity suppression, sterilization, etc. Synthetic pesticides lead to serious problems like environmental pollution, health hazards and insect resistance to insecticides. Study of egg, larvae and pupae affected by the testing of different concentrations of some biocide showed an increased mortality over the control. The results have been discussed in the light of biopesticides as good alternative for the synthetic pesticides used in mosquito control.

Abstract

Food intake is an important factor governing growth and reproduction and it is depend upon the quality and chemical composition of the feed. A comparative study was conducted to test the effect of Spirulina incorporated diet over the commercially available feed on bioenergetics and biochemical parameters of fish Cirrhinus mrigala. Spirulina incorporated diets were formulated to contain Spirulina at the level of 0.25, 0.50 and 1.0%. The results showed a better growth rate, feeding rate and absorption rate in the fish fed with Spirulina incorporated diet compared to commercial feed. The study also revealed that protein, carbohydrate and lipid contents were increased in fish with Spirulina incorporated diet.
