Large-scale deployment of seed treatments has driven rapid increase in use of neonicotinoid insecticides and preemptive pest management in US field crops.
It is suggested that carefully targeted efforts could considerably reduce neonicotinoid use in field crops without yield declines or economic harm to farmers, reducing the potential for pest resistance, nontarget pest outbreaks, environmental contamination, and harm to wildlife, including pollinator species.
Biology, Ecology, and Management of Brown Marmorated Stink Bug (Hemiptera: Pentatomidae)
Pesticide applications, including broad-spectrum insecticides, have increased in response to H. halys infestations, potentially negatively influencing populations of beneficial arthropods and increasing secondary pest outbreaks.
Herbivore exploits orally secreted bacteria to suppress plant defenses
The findings show that the herbivore exploits symbiotic bacteria as a decoy to deceive plants into incorrectly perceiving the threat as microbial, and by interfering with the normal perception of herbivory, beetles can evade antiherbivore defenses of its host.
Bee nutrition and floral resource restoration.
Genotypically diverse cultivar mixtures for insect pest management and increased crop yields
The objective is to review the literature documenting the benefits of genotypic diversity for natural and agricultural ecosystems and synthesize the evidence in support of intraspecific diversity as a viable pest management strategy for insect pests of field crops.
Seeds of Change: Corn Seed Mixtures for Resistance Management and Integrated Pest Management
It is concluded that Seed mixtures will make pest monitoring more difficult and that seed mixtures may make IRM riskier because of larval behavior and greater adoption of insecticidal corn.
Gall insects can avoid and alter indirect plant defenses.
Infestation by E. solidaginis appeared to suppress volatile responses to subsequent attack by the generalist caterpillar, which may reduce the predation risk for the gall inducer and the subsequent herbivore, and could influence community-level dynamics, including the distribution of herbivorous insect species associated with S. altissima.
Neonicotinoid insecticide travels through a soil food chain, disrupting biological control of non-target pests and decreasing soya bean yield
Thiamethoxam-based seed treatments depressed activity–density of arthropod predators, thereby relaxing predation of slugs and reducing soya bean densities by 19% and crop yield, revealing a previously unconsidered ecological pathway through which neonicotinoid use can unintentionally reduce biological control and crop yields.
Macronutrient ratios in pollen shape bumble bee (Bombus impatiens) foraging strategies and floral preferences
It is demonstrated that bumble bees selectively collect pollen from host-plant species based on the protein:lipid ratios of pollen, and macronutritional ratios appear to be a primary factor driving bee pollen-foraging behavior.
