Abstract

Terpenoids of Caparis spinosa was tested against Musca domestica . study results rcveald that crude terpenoids extracts of leaves and fruits significantly affected some aspects of housfiy .Egg production was droped from about 1147 egg / femal to 498 and555 eggs/femal when theinsect reared on diets treated with leaves and fruits terpenoids respectively , at concentration of 20 nig! ml .Cunimulative mortality of immature stages readied 72 % and 62 % at the same concentration , developmental period was exteneded to 17 and 15.2 days when treated with both extracts . compared with control ( 11 days ).Pupal wt. also, reduced significantly and reached 0.16 ( gm / 30 pupa ) and 0.18 ( gtn / 30 pupa ) compared with 0.89 gm / 30 pupa of control treatment.
