Silks are strong protein fibers produced by a broad array of spiders and insects. The vast majority of known silks are large, repetitive proteins assembled into extended beta-sheet structures. Honeybees, however, have found a radically different evolutionary solution to the need for a building material. The 4 fibrous proteins of honeybee silk are small ( approximately 30 kDa each) and nonrepeti...

Examination of Hkamti and Tanai Burmese ambers reveals two new genera species †Lancepyrinae: Protopyris myanmarensis Jouault & Nel gen. et sp. nov. Burmapyris azevedoi Jouault, Perrichot is the first Bethylidae described from amber deposit (lower Albian, mid-Cretaceous) in Myanmar. These specimens provide useful clues to understand paleobiogeographic evolution †Lancepyrinae, since they are only...

Accepted 5 January 1999 Carpenter, J. M. (1999). What do we know about chrysidoid (Hymenoptera) relationships?. Ð Zoologica Scripta 28, 215±231. The phylogeny of the superfamily Chrysidoidea is reviewed. Relationships among the families proposed by Carpenter (1986) were confirmed by Brothers and Carpenter (1993). The status of knowledge of phylogenetic relationships within families is assessed....

The goals of this study were to identify pupal parasitoids of the asparagus miner, Ophiomyia simplex Loew (Diptera: Agromyzidae), and examine the effect of different diets and floral resources on the lifespan of adult asparagus miners and their parasitoids. We also measured the effect of parasitism on stem damage caused by the asparagus miner. The identity and abundance of the parasitoids of th...
