Abstract

Corcyra cephalonica are important polyphagous storage pest which are used as a laboratory host for rearing as well as for mass production of various parasitoids and predators. For invitro and invivo studies of various biocontrol agents, mass rearing is one of an important aspects and C. cephalonica play an important role in mass production of the bioagents. However the population of C. cephalonica also needs to be maintain in-vitro for the desired production of the bioagents. Therefore, the present studies aims to evaluate performance of C. cephalonica in four different stored grains diet i.e., rice, wheat, maize and sorghum for best rearing. Among the tested diets, the sorghum based diet provided minimum larval period, maximum larval weight, minimum pupal period, maximum pupal period, shorter developmental period and maximum adult longevity and proved to be the best for rearing of Corcyra. Also the higher fecundity was observed in sorghum which was observed to be at par with maize diet. Therefore considering the over all superior performance, sorghum based diet can be utilized for successful rearing of C. cephalonica.

Conclusion

Considering the various parameters taken under study for rearing of C. cephalonica in rice, wheat, maize and sorghum diet, it was evident that the insect when reared in sorghum performed superior over the other diets. The over all growth, development, and performance was observed better in sorghum diet. Therefore, it can be concluded that the sorghum being an efficient diet can be used for the mass production of the eggs of C. cephalonica as compared to the other tested diets.
