The biology, egg and larvae of Acaenitus dubitator (Panzer) (Hymenoptera, Ichneumonidae: Acaenitinae)
Acaenitus dubitator (Panzer) is found to be a koinobiont endoparasitoid of the larva of an endophytic beetle, Cleonis piger (Scopoli) (Curculionidae), in Britain, suggesting a similar mode of development for the ichneumonid subfamily Acaenitinae as a whole. The parasitoid can overwinter in its cocoon in one of two ways. Individuals...Shaw, Mark R ; Wahl, D B

First host record for the rogadine genus Pholichora van Achterberg (Hymenoptera:Braconidae) with description of a new species and notes on convergent wing venation features
The wasp genus Pholichora is recorded as parasitic on geometrid moth larvae on the basis of a new species, P. subscleroma sp. nov., from South Africa (Natal), reared from Ascotis reciprocaria (Lepidoptera: Geometridae, Ennominae). The discovery of this new species necessitates a reassessment of the characters separating Pholichora from Hemigyroneuron....Quicke, D L J ; Shaw, Mark R

Synthesis and reactions of 4-aryloxyflavans
4α-Aryloxyflavans unsubstituted in ring A have been synthesised by the reaction of phenols with flavan-4β-ols in the presence of boron trifluoride in ether. If reaction times are prolonged beyond disappearance of the starting 4β-ols, thermodynamic control leads to 4-arylflavans and the yields of 4-aryloxyflavans are negligible. 4-Arylflavans are the sole...Bateman, G ; Brown, B R ; Campbell, J B ; Cotton, C A ; Johnson, P …
