Abstract

The lesser pumpkin fly, Dacus ciliatus Loew (Dip.: Tephritidae) is an agricultural pest of major significance worldwide that primarily attacks cucurbit crops. Dynamic population studied by random sampling of cucumber fruits and using pheromonal traps. Studies were conducted to evaluate the toxicity of methanol (MeOH) extract of Ferula asafoetida and Sclerorhachis leptoclada leaves to adult and larvae of the lesser pumpkin fly, Dacus ciliatus (Dip.: Tephritidae). Direct-dip bioassays for larvae and topical bioassays for adults of fly used to assess mortalities. The chemical constituent of extract was analyzed by GC/MS. The results shown the population density increased from August to October and then decreased afterward. The toxicity of F. asafetida for larvae (LC50= 7.3 mg/ml) and adults (LC50= 0.41 mg/insect) were about 14 and 11 times more than S. leptoclada lethal effects, respectively. The test showed that the repellency was concentration-dependent and the repellency increased significantly with increasing concentration. Ethanol extract of Ferula asafoetida contained thiol compounds such as Thiophene and Phenolic compounds. Ethanol extract of Sclerorhachis leptoclada contained Terpenoide compounds.
