Investigating zeta‐cypermethrin resistance stability in California Drosophila suzukii populations

Pest Management Science, EarlyView.
After continuous selection and removal of selection pressure in spotted‐wing Drosophila, zeta‐cypermethrin resistance remained stable over several generations. Following a population bottleneck, zeta‐cypermethrin resistance increased without selection, highlighting the importance of insecticide rotation.

Bacillus thuringiensis and its pest control potential as endophyte

Pest Management Science, EarlyView.
Bacillus thuringiensis (Bt) systemically colonizes tomato plants as endophyte, inducing midgut damage, fitness reduction and immune suppression in Spodoptera littoralis larvae feeding on Bt‐colonized leaves. The immune suppression enhances the susceptibility to Bt treatments, allowing a synergistic dual use of Bt commercial formulations, by combined ...

Cellular and Secretory Proteins of the Salivary Glands of \u3cem\u3eSciara coprophila\u3c/em\u3e During the Larval-pupal Transformation [PDF]

, 1972
The cellular and secretory proteins of the salivary gland of Sciara coprophila during the stages of the larval-pupal transformation were examined by electrophoresis in 0.6 mm sheets of polyacrylamide gel with both SDS-continuous and discontinuous buffer ...

Treatment of cotton with plant growth‐promoting rhizobacteria consortium alters host location and oviposition of Spodoptera exigua

Pest Management Science, EarlyView.
Two plant‐growth promoting rhizobacteria (PGPR) consortia (AU8 and TX1) induced a deterrence of host plant location and oviposition behavior of Spodoptera exigua females in both susceptible and resistant cotton plants. Most of the volatile organic compounds (VOCs) increased in PGPR‐treated plants compared to untreated plants. # indicates treatments not

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.

Fitness costs associated with Vip3Aa resistance on various hosts in Helicoverpa zea

Pest Management Science, EarlyView.
Significant fitness costs associated with Vip3Aa resistance in H. zea were observed across three non‐Bt hosts. Abundant non‐Bt refuges could help limit the spread of Vip3Aa resistance in H. zea in the field. Abstract BACKGROUND Transgenic crops containing Bacillus thuringiensis (Bt) proteins are crucial for managing major agricultural pests such as the
