Evaluation of some alternative carriers to wheat bran on the fourth Nymphal instar of Euprepocnemis plorans plorans and Heteracris annulosa [electronic resource].

Includes references.

Studies were carried out to evaluate some alternative carriers to wheat bran and the preferred carriers in the presence of green food plant, berseem, Trifolium atexandrinum and maize, Zea mays on the grasshoppers, Euprepocnemis plorans plorans and Heteracris annulosa. The carriers used in the study were wheat bran, corn hull, bean hay, groundnut husts, berseem hay, wheat hay, rice husks and saw-dust. No significant differences were observed between the four preferential carriers, i.e. wheat bran, bean hay, corn hull and groundnut husks. The descending order of the consumed amount of the carriers in gm. per gm. b.wt. of E. plorans : Wheat bran> bean hay>corn hull> groundnut husks> berseem hay> rice husks>wheat hay= saw dust. Concerning H. annulosa, carriers could be arranged descendingly as follows : corn hull> wheat bran> bean hay> groundnut husks> berseem hay> wheat hay> rice husks> saw-dust. However, the grasshopper, H. annulosa. consumed less amounts of the carriers than the other one.
