KURIS, A. M., 1973. Biological control: implications of the analogy between the trophic interactions of insect pest-parasitoid and snail-trematode systems. Experimental Parasitology 33, 365-379. An analogy between the tropic interactions of insect pest-hymenopterous parasitoid and snail-larval trematode systems is proposed. The goal of most agricultural pest management programs is increase in p...

We sequenced the nuclear ribosomal internal transcribed spacer region 2 (ITS2) from several glassy-winged sharpshooter (GWSS) [Homalodisca vitripennis Germar (=H. coagulata Say)] egg parasitoid species (Hymenoptera: Mymaridae) belonging to the genus Gonatocerus Nees to test the utility of this fragment to confirm species boundaries and to define phylogenetic relationships. A total of 35 specime...

summary) Apples: Both SOFT and CONV treatment regimes were able to maintain injury from codling moth (CM) at a very low level across the AWII project, even in the face of increasing CM pressure throughout most of the growing areas of Washington state. CM pressure varied in the AWII project from low-moderate in most blocks to high at two of the orchards (A3 and A5). On average, there was no real...
