Differences in Dormancy Characteristics among Populations of Aphelinus asychis (Hymenoptera: Aphelinidae).

First report of Aphelinus semiflavus Howard, 1908 (Hymenoptera: Aphelinidae) in Brazil.

Temperature adaptability of two clades of Aphelinus mali (Hymenoptera: Aphelinidae) in China

Aphelinus mali (Haldeman) (Hymenoptera: Aphelinidae) is an effective natural enemy used in China to control the woolly apple aphid (Eriosoma lanigerum [Hausmann]) (WAA). Population of A. mali in China falls into two distinct genetic clades (Shandong clades and Liaoning clades). In the present results, the developmental threshold temperature of the Shandong clade (9.82 ± 1.44 °C) was lower than ...

Susceptibility of Aphelinus certus (Hymenoptera: Aphelinidae) to neonicotinoid seed treatments used for soybean pest management.

Soybean aphid is an economic pest of soybean in North America. Currently, management of soybean aphid is achieved through the use of foliar- and seed-applied insecticides. However, natural enemies play an important role in regulating soybean aphid populations, and may be adversely affected by insecticides. The effects of imidacloprid and thiamethoxam seed treatments on the soybean aphid parasit...

Molecular Evidence for a Species Complex in the Genus Aphelinus (Hymenoptera: Aphelinidae), with Additional Data on Aphidiine Phylogeny (Hymenoptera: Braconidae)

Mitochondrial 16s rDNAwas sequenced fromninedifferentpopulationsofAphelinidae and 10 of aphidiinae. Sequence divergences between populations within a species are low, ranging from 0 to 0.38%. Divergences among species within the same genus range from 0 to 8.71%. Aphelinus asychisWalker has a sequence divergence from the otherAphelinus spp. of 8.71%,which is evenhigher than the divergences among...
