A survey on the genus Bracon Fabricius, 1804 was conducted in Hormozgan province, Southern Iran, during February 2011-July 2012. In all, 19 species belonging to seven subgenera were collected and identified, of which seven species and the subgenus Asiabracon Tobias, 1957 are recorded for first time from Iran. Bracon (Orthobracon) persiangulfensis Ameri, Beyarslan & Talebi sp. n. is newly descri...

Habrobracon females homozygous for the mutant ebony produce about 5% mosaic progeny among fertilized eggs. The present experiment demonstrates by means of a test-cross method that in the production of these mosaics only one pronucleus is involved, and that this nucleus cleaves before union of one of its daughter nuclei with the sperm nucleus.

Received January 16, 1961 A LTHOUGH the irradiation of Drosophila results in more crossover off spring, it has not been demonstrated that this effect has its origin in meiosis (WHITTINGHILL 1955) rather than in gonia1 exchange. Hence it is appropriate to irradiate specimens or stages which may have only oijgonia rather than the mixture of gonia and gametocytes carried by adults. Previous experi...

The survival of stored product insect natural enemies in wheat treated with spinosad was investigated in laboratory and pilot scale experiments. The predator Xylocoris flavipes (Reuter), the warehouse pirate bug, and the parasitoids Habrobracon hebetor (Say), Theocolax elegans (Westwood), and Anisopteromalus calandrae (Howard) were exposed to wheat treated with aliquots of water or spinosad at ...
