Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Forecasting the global extent of invasion of the cereal pest Spodoptera frugiperda, the fall armyworm

bioRxiv, 2018
Fall armyworm, Spodoptera frugiperda, is a crop pest native to the Americas, which has invaded and spread throughout sub-Saharan Africa within two years. Recent estimates of 20-50% maize yield loss in Africa suggest severe damage to livelihoods.

Larval antibiosis to cabbage stem flea beetle (Psylliodes chrysocephala) is absent within oilseed rape (Brassica napus)

Pest Management Science, EarlyView.
We screened a panel of 98 Brassicaceae genotypes (97 Brassica napus and 1 Sinapis alba) for cabbage stem flea beetle (Psylliodes chrysocephala) larval antibiosis. We found limited evidence for antibiosis across B. napus but consistent antibiosis in S. alba. Brassicaceae relatives may therefore better inform resistance traits for breeding.

Identification of broadly expressed nervous system‐related genes as effective RNAi targets in the brown marmorated stink bug, Halyomorpha halys

Pest Management Science, EarlyView.
Broadly expressed genes outperformed brain‐enriched neural targets as RNAi candidates in Halyomorpha halys. Microinjection of dsRNA targeting alpha‐soluble NSF attachment protein (Asnap) or Ras opposite protein (Rop) caused strong feeding suppression and near‐complete mortality, identifying them as promising targets for future oral or spray‐based RNAi ...

Diversity of short interspersed nuclear elements (SINEs) in lepidopteran insects and evidence of horizontal SINE transfer between baculovirus and lepidopteran hosts

BMC Genomics, 2021
Background Short interspersed nuclear elements (SINEs) belong to non-long terminal repeat (non-LTR) retrotransposons, which can mobilize dependent on the help of counterpart long interspersed nuclear elements (LINEs).
