Transgenic corn and cotton that produce Cry and Vip3Aa toxins derived from (Bt) are widely planted in the United States to control lepidopteran pests. The sustainability of these Bt crops is threatened because the corn earworm/bollworm, (Boddie), is evolving a resistance to these toxins. Using Bt sweet corn as a sentinel plant to monitor the evolution of resistance, collaborators established 146 trials in twenty-five states and five Canadian provinces during 2020-2022.

Bacterial coinfections have the potential to increase outbreak severity and can worsen on-farm mortality. A preliminary assessment of in vivo bacterial coinfection with (S97-773) and (ALG-00-530) was conducted using juvenile channel catfish ().

Pre- and post-pandemic seafood purchasing behavior in the U.S.

The global COVID-19 pandemic resulted in an unprecedented economic shock in current times. Previous literature on consumer shopping behaviors during economic downturns is limited, and studies specific to seafood focused primarily on supply-side shocks. A national survey was conducted using an online platform from February 22 to April 6, 2021 that targeted 100 seafood consumers in each of 20 market areas across the U.

Chlorantraniliprole Residual Control and Concentration Determination in Cotton.

Studies were conducted in 2020 and 2021 at the Delta Research and Extension Center in Stoneville, MS, to determine the residual concentrations of chlorantraniliprole in cotton (, L.) leaves, as well as the concentrations in petals and anthers that developed after the time of application. Foliar applications of chlorantraniliprole were applied at four rates for leaves and two rates for petals and anthers at the second week of bloom.

Defining Fungicide Resistance Mechanisms in the Population from Mississippi Soybean.

Target spot, caused by , is a common lower canopy soybean disease in the southern United States. Recently, target spot has resurged in importance especially following the identification of resistance to the quinone outside inhibitor (QoI) fungicides. As a result, a survey of from soybean throughout Mississippi began in 2018.

Evaluating In Vitro Fitness Parameters of G143A-Containing and Wild-Type Isolates from Mississippi Soybean.

Quinone outside inhibitor (QoI) fungicides have been widely used to manage diseases of soybean including target spot caused by . However, resistance to QoI fungicides has recently been reported within the population from Alabama, Arkansas, Mississippi, and Tennessee as a result of isolates in the population containing the G143A amino acid substitution. Therefore, the relative fitness and stability of isolates containing the G143A substitution compared with wild-type isolates from Mississippi soybean were investigated by analyzing several fitness parameters in vitro.

The molecular basis of socially induced egg-size plasticity in honey bees.

Reproduction involves the investment of resources into offspring. Although variation in reproductive effort often affects the number of offspring, adjustments of propagule size are also found in numerous species, including the Western honey bee, . However, the proximate causes of these adjustments are insufficiently understood, especially in oviparous species with complex social organization in which adaptive evolution is shaped by kin selection.

Regional analysis of planting date and cultivar maturity recommendations that improve soybean oil yield and meal protein concentration.
