Abstract

Stegobium paniceum was transporting from field to storage to infest Apiaceae fruits hardly. Thus the fruits were loosed and their economic value was reduced. The percentage of infestation with this insect was differed according to Apiaceae plants. Therefore, the aim of yje present work is to study the effect of different Apiaceae fruits on the biology of this insect.
             The average number of eggs/female was 40.25 eggs during 5 to 7 days. Incubation period ranged from 8 to 13 days, and the percentage of hatching ranged from 76 to 86 %.
             The larva of S. paniceum have five instars.
             The more suitable doet to S. paniceum laevae is the milled caraway followed by coriander. Khella, dill, cumin and fennel were unsuitable diets. The duration of larval stage was affected by the type of food. The total larval duration ranged from 49 to 60 days when the larvae were reared on caraway and from 52 to 68 days on coriander milled fruits. The larvae were died in the first instar on khella and dill, in the second instar in cumin, and in the fourth instar on fennel. Meanwhile, the larvae were capable to survive and complete their larval stage when reared on caraway and coriander.
             The duration of pupa ranged from 4 to 7 days when reared on caraway and ranged from 4 to 5 days on coriander.
             The adults longevity was affected by the type of larval food. In case of caraway, the adults were survived from 23 to 38 days, while in case of coriander it survived from 15 to 27 days.
