İndole-3-asetik asitin (IAA) parazitoit Bracon hebetor Say (Hymenoptera: Braconidae)’un bazı biyolojik özelliklerine etkileri araştırılmıştır. Farklı konsantrasyonlarda IAA (5, 50, 100, 500 and 1000 mg L-1) konukçu larvaların yapay besinine ilave edilmiştir. Bu konukçularda yetiştirilen parazitoitlerin gelişim süresi, ergin ömür uzunluğu, verim ve eşey oranı konsantrasyonlarına göre değerlendir...

The quantity and quality of host insect diets is strongly related with the development parasitoid offspring. To evaluate prediction that effects artificial on ecto-larval Bracon hebetor Say (Hymenoptera: Braconidae); Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) larvae were reared different diets. We used corn flour + bran (control), oat bran, rye carob einkorn potato (1:1) as diet. numbe...

Egg dispersion and the sex ratio of progeny were studied in relation to the host density of the parasitoid, Bracon hebetor Say, infesting larvae of Plodia interpunctella (H . ubner). Females appeared to allocate eggs in relation to host density to avoid laying more eggs than could complete development on a host. The dispersion pattern of the parasitoid ovipositions among hosts was influenced by...

FTER WHITING (1940a, 1943) established conclusively that sex in the A parasitic hymenopteron Habrobracon is controlled by multiple sex alleles, it became of interest to determine whether the same mechanism exists in other insects, in which males develop from unfertilized eggs and are haploid. The work described in this paper was started in 1944 at the SOUTHERN STATES BEE CULTURE LABORATORY, of ...
