Abstract Recent efforts to evaluate the contribution of neonicotinoid insecticides worldwide pollinator declines have focused on honey bees and chronic levels exposure experienced when foraging crops grown from neonicotinoid-treated seeds. However, few studies address non-crop plants as a potential route other insecticides. Here we show that pollen collected by bee foragers in maize- soybean-dominated landscapes is contaminated throughout growing season with multiple agricultural pesticides,...

Summary Neonicotinoid insecticides are routinely used as seed treatments on most grain and oilseed crops in the USA , yet extent likelihood of spread insecticide residues during planting has not previously been quantified. Honey bees, Apis mellifera highly mobile sensitive to neonicotinoid residues, presenting an opportunity estimate non‐target exposures neonicotinoids insects. We measured dust drift maize sowing sites fields, apiary locations honey bee foraging radii forager exposure....

1. Predator–prey interactions have traditionally focused on the consumptive effects that predators prey. However, can also reduce abundance of prey through behaviourally‐mediated non‐consumptive effects. For example, pea aphids ( Acyrthosiphon pisum Harris) drop from their host plants in response to risk attack, reducing population sizes as a consequence lost feeding opportunities. 2. The objective present study was determine whether could extend non‐prey herbivore populations result...

Studies manipulating predator diversity and measuring the impact on herbivore abundance have found that enhancing species richness often increases strength of prey suppression. This relationship may be due to mechanisms such as complementarity or facilitation, which are considered "true" benefits because greater suppression is an emergent property multispecies community. Or it identity effect, "apparent" benefit results from likelihood including one particularly voracious total number...

A 2 year study was conducted to determine whether western bean cutworm (Striacosta albicosta Smith) (WBC) larval feeding damage increases severity of the fungal disease Gibberella ear rot [Fusarium graminearum (Schwein.) Petch] in field corn (Zea mays L.). The effect a quinone-outside inhibiting fungicide, pyraclostrobin, on and mycotoxin production, both with without WBC pressure, also evaluated. impact each variable assessed individually combination upon severity.There positive correlation...

Abstract The carrot weevil, Listronotus oregonensis (LeConte) (Coleoptera: Curculionidae), is a devastating pest of high value Apiaceous crops like carrots (Daucus carota subsp. sativusHoffm.), parsley (Petroselinum crispum (Mill.) Fuss), and celery (Apium graveolens L.). Although native to North America, it serious across the Eastern United States Great Lakes region Canada. Females deposit eggs in petiole cultivated hosts, upon hatching, larvae tunnel down through into plant roots causing...

Abstract Most field corn in the United States receives a neonicotinoid seed treatment for management of early-season, soil-dwelling insect pests. Grubs Maladera formosae (Brenske) (Coleoptera: Scarabaeidae) have been reported feeding on young with both low and high rates clothianidin treatments Indiana, Michigan, Ohio. Anecdotally, these infestations are restricted to sandy soils region. The purpose this study was (1) evaluate whether grub populations soils, (2) assess soil type influences...

Abstract The Asiatic garden beetle, Maladera formosae Brenske (AGB), has become a significant pest of commercial mint fields in northern Indiana. Larval feeding on roots can cause stunted growth and plant death when densities are high. Sampling approaches that provide reliable estimates larval have not been established, leaving farmers without the knowledge necessary to implement integrated management (IPM) strategies. To address this gap, we evaluated strategies for estimating AGB...

<h3>Abstract</h3> <h3>Background and goals</h3> New pesticide spray technologies are needed to replace inefficient conventional air-assisted practices for protecting grapes from diseases insect pests. <h3>Methods key findings</h3> A laser-guided intelligent sprayer was evaluated in an experimental vineyard three consecutive growing seasons. Treatments included the with low (0.065 L/m³) high (0.13 base deposition rates, constant-rate application using same but functions deactivated...

Spotted-wing Drosophila, Drosophila suzukii, is an economically important pest of small fruits worldwide. Currently, the timing management strategies relies on detection adult flies captured in baited monitoring traps; however, identifying D. suzukii trap catch based morphology can be challenging for growers. DNA-based diagnostic methods such as loop-mediated isothermal amplification (LAMP) have potential to improve detection. This study evaluated a LAMP assay tool discriminate between and...

Abstract Knowledge of specialty crop cultivars with resistance against insect pests is limited, and this may serve as a barrier to implementing host-plant part an integrated pest management strategy. Carrot (Daucus carota L.) (Apiaels: Apiaceae)is valuable diversity that differ in physical chemical qualities influence preferences. To investigate the role cultivar tool reduce damage, we evaluated 7 carrot replicated laboratory field trials IN OH, USA 2021. During June July, documented...
