Pratylenchus quasitereoides n. sp. from cereals in Western Australia.

Pratylenchus quasitereoides n. sp. is described from Western Australia.

Impact of the biological control agent Mesoclanis polana (Tephritidae) on bitou bush (Chrysanthemoides monilifera subsp. rotundata) in eastern Australia.

The seed fly Mesoclanis polana (Diptera: Tephritidae) was released in Australia in 1996. Its impact on seed production of bitou bush (Chrysanthemoides monilifera subsp. rotundata) was monitored at eight sites along the New South Wales coast from 1996 to 2004.

A highly divergent gene cluster in honey bees encodes a novel silk family.

The pupal cocoon of the domesticated silk moth Bombyx mori is the best known and most extensively studied insect silk. It is not widely known that Apis mellifera larvae also produce silk. We have used a combination of genomic and proteomic techniques to identify four honey bee fiber genes (AmelFibroin1-4) and two silk-associated genes (AmelSA1 and 2).

Selective herbivory by Christmas beetles in response to intraspecific variation in Eucalyptus terpenoids.

Between-tree variation in the terpenoid composition in the foliage of six species of Eucalyptus was investigated in relation to its effects on herbivory by Christmas beetles (Anoplognathus spp.). All six eucalypt species showed considerable intraspecific variation in terpenoid composition; the cineole content ranged from 13% to 78% of the total oil in different E.

Effects of ivermectin residues in sheep dung on the development and survival of the bushfly, Musca vetustissima Walker and a scarabaeine dung beetle, Euoniticellus fulvus Goeze.

During produced by sheep for up to 1 week post-treatment (drenching) with ivermectin caused significant mortality to newly emerged larvae of the bushfly Musca vetustissima. Dung from sheep drenched with a mixture of levamisole and oxfendazole also resulted in larval mortality, but here the effect was limited to the first 48 h after treatment. Flies reared through to the adult stage on dung collected up to 32 days post-drenching were tested for evidence of fluctuating asymmetry, which is an indicator of developmental stress.
