Farklı Depolama Tiplerinin Buğday Biti Sitophilus granarius L Coleoptera Curculionidae nin Gelişmesi Üzerine Etkisi

In this study, it was investigated the effect of storage form

(grain-spike), grain moisture content (12, 14, 16%), storage temperature

(10, 20, 30 ˚C), storage period (3, 6

month) on the number of granary weevil, Sitophilus granarius (L.) and

rate of infestations in stored cereals. Bezostaya and Krik bread wheat

varieties were used in the storage study as grain and spike. At the beginning

of storage, five granary weevils were placed into per glass jar and reared

on wheat under controlled environmental conditions. During storage, insect

development and damaged grain were higher in storage media of Krik variety than

that of Bezostaya variety. After storage period, the

number of granary weevil and damaged grain were determined. The increase in the

grain moisture content, storage temperature and time resulted in increase in

the number of granary weevil and damaged grain. The amount of damaged grain and

granary weevil of wheat stored in spike form was lower than wheat stored in

grain form. For this reason, wheat stored in spike form was more tolerant than

wheat stored in grain form to insect damage.<o:p></o:p>
