Mortality of the cotton boll weevil in drip and sprinkler irrigated cotton crops

Brazilian Journal of Biology, 2021
The cotton boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is a key cotton crop pest in Brazil. Adverse climatic factors, such as high temperatures and low soil moisture, dehydrate oviposited cotton squares (bud flowers) on ...

COntrol of Root Weevil in Red Raspberry, 1996B [PDF]

Arthropod Management Tests, 1997
Abstract Trials were conducted in a mature field of ‘Chilliwack’ red raspberries in Vancouver, WA. Treatments were replicated 4 times on 9 X 30 ft plots in a RCB design. Sprays were applied on 18 Jun along the lower 3 feet of canes with a 2-ft hand-held boom sprayer equipped with 3 hollow cone D4-45 TeeJet nozzles at 150 psi that ...

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

Pest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Root Weevil Control on Red Raspberry, 1997

Arthropod Management Tests, 1998
Abstract Treatments were replicated five times in a 4-year-old ‘Chilliwack’ raspberry field j in Vancouver, WA. Plots measuring 1 row wide and 30 ft long were arranged in a RCB design. Full coverage sprays were applied on 10 Jun with a tractor-mounted 6-tank plot sprayer with an over-the-row boom.

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.

Intraspecific Variation in Plant Defense Alters Effects of Root Herbivores on Leaf Chemistry and Aboveground Herbivore Damage

, 2008
Root herbivores can indirectly affect aboveground herbivores by altering the food quality of the plant. However, it is largely unknown whether plant genotypes differ in their response to root herbivores, leading to variable defensive phenotypes.

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

Pest 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.

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

Dispersal of soil-dwelling clover root weevil (Sitona lepidus Gyllenhal, Coleoptera: Curculionidae) larvae in mixed plant communities

, 2010
Insect pests that have a root-feeding larval stage often cause the most sustained damage to plants because their attrition remains largely unseen, preventing early diagnosis and treatment.
