Orientation-dependent photonic bandgaps in gold-dust weevil scales and their titania bioreplicates

open access: yesBeilstein Journal of Nanotechnology
The scales of the gold-dust weevil Hypomeces squamosus are green because of three-dimensional diamond-type chitin–air photonic crystals with an average periodicity of about 430 nm and a chitin fill fraction of about 0.44.

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

open access: yesPest 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.

Bt agave: why it is time to explore a new biotechnological frontier

open access: yesPest Management Science, EarlyView.
Drylands cover 41% of Earth, requiring sustainable crops. Agave, drought‐ and heat‐adapted, offers high‐value products with low water needs. Pests limit yield, yet Bacillus thuringiensis (Bt) Cry proteins, successful in other plants, remain unexploited in Agave.

Deposition and longevity of oviposition-deterring pheromone in the cabbage seed weevil

open access: yes, 1991
The cabbage seed weevil (Ceutorhynchus assimilis Payk.) lays eggs singly into pods of oilseed rape (Brassica napus L.) through punctures bored with the mouthparts, preferring pods not recently used for oviposition.

Behavioural manipulation of the cabbage stem flea beetle (Psylliodes chrysocephala L): Prospects for push–pull strategies in oilseed rape

open access: yesPest Management Science, EarlyView.
Behavioural manipulation of Psylliodes chrysocephala provides promising opportunities for sustainable pest management in oilseed rape systems. This review synthesises evidence on glucosinolates and their volatile isothiocyanate derivatives as phagostimulants and attractants, alongside the repellent or antifeedant effects of non‐host plants, plant ...
