Metabolite‐based resistance in wheat varieties to aphid virus vectors: progress and future opportunities

open access: yesPest Management Science, EarlyView.
Sitobion avenae and Rhopalosiphum padi are major pests on wheat. Natural product‐based aphid resistance holds promise for the sustainable control of these pests. The current literature is discussed, highlighting knowledge gaps and challenges that need addressing. Abstract Cereal aphids, Sitobion avenae and Rhopalosiphum padi, cause severe yield loss in

Seasonal occurrence of brown marmorated stink bug and its impact in organic and conventional kiwifruit orchards in north‐western China

open access: yesPest Management Science, EarlyView.
Higher populations of brown marmorated stink bug (BMSB) and increased kiwifruit damage were recorded in organic orchards, BMSB population exhibiting a consistent pattern of two generations annually over 3 years. Feeding damage peaked at 59% and 60% in October 2019 and 2021, respectively, with no significant differences in overall damage rates between ...

Differential Nest Parasitism in Three Sympatric Social Wasps (Hymenoptera: Vespidae: Polistes spp.) in the West Indies

open access: yesSociobiology, 2015
Jamaica's three species of social wasps were found nesting together in a suburban area.  Their nests gave evidence of markedly different parasitoid loads in the sequence Polistes crinitus > P. dorsalis > P. major.  Based on larval and pupal silk remains,

Persistent pods of the tree Acacia caven: a natural refuge for diverse insects including Bruchid beetles and the parasitoids Trichogrammatidae, Pteromalidae and Eulophidae [PDF]

open access: yesJournal of Insect Science, 8 (12/06/2006) 1-9 pages, 2007
The persistent pods of the tree, Acacia caven, that do not fall from the tree provide opportunities for the appearance of a diverse group of insects the following season. Such pods collected during the spring of 1999 in Chile were indehiscent with highly sclerified pod walls.
