| Abstract | ||||
| the present work was conducted to evaluate some novel artificial diets for larvae and adults on some biological aspects of Med-fly, Ceratitis capitata (Wied.). Five different artificial diets for larvae consisted of wheat bran, grinded faba bean peel, wheat bran + grinded faba bean peel (1:1), wheat bran + grinded faba bean peel (1:2) and wheat bran + grinded faba bean peel (2:1) were used. Also, five different artificial diets for Med-fly adults consisted of sugar, sugar + protein hydrolyzate (3:1), sugar + alternative protein (1:1), alternative protein and protein hydrolyzate only were evaluated. The obtained results revealed that larval mortality (%) was high when larvae reared on grinded faba bean peel diet alone (29.4%). Pupal recovery (%) was lower when larvae reared on the grinded faba bean peel diet alone compared to the other diets. Rearing larvae of C. capitata on grinded faba bean peel diet alone produced smaller pupal weights, whereas diets contained mixture of wheat bran and grinded faba bean peel gave highest pupal weight compared to the standard diet. The oviposition period prolonged to 41.5 days when larvae reared on grinded faba bean peel diet alone but it, shorted to 16.5 days when larvae reared on diet contained wheat bran + grinded faba bean peel (1:1). Longevity of adult female and males prolonged to 48.3 and 48.8 days when larvae fed on grinded faba bean peel diet alone and shorted to 19.7 and 23.2 days when larvae fed on diet contained wheat bran + grinded faba bean peel (1:1). The highest adult emergence (%) occurred when larvae reared on wheat bran diet and slightly decreased when wheat bran mixed with grinded faba bean peel. Fecundity of C. capitata females whose larvae reared on the tested diets was relatively lower, the highest mean number of deposited eggs/female was found when larvae reared on wheat bran diet and mixture of wheat bran + grinded faba bean peel, while rearing larvae on grinded faba bean peel diet alone reduced deposited eggs/female. On the other hand, oviposition period of C. capitata females extended to 21.2 days when female adults fed on diet contained sugar + alternative protein (1:1) and reduced to 14.7 - 15.1 days whenfemale fed on the standard diet and alternative protein diet, respectively. Feeding females on diet that contained sugar only reduced the oviposition periods to 11.1 days whereas feeding females on protein hydrolyzate diet alone reduced the oviposition period to the minimum (1.53 days). The fecundity of C. capitata was higher (79.4eggs/female) when females fed on a standard diet (sugar + protein hydrolyzate at 3: 1) and reduced when females fed on sugar + alternative protein (1:1) diet and alternative protein diet. Feeding females on sugar only reduced the deposited eggs (10.7eggs/female) whereas feeding females on protein hydrolyzate only without sugar produced few numbers of eggs. Generally, the tested diets for rearing adults of C. capitata need additional studies on nutrient requirements to optimize the rearing process and improve the production of eggs at lower costs. | ||||
