Article Synopsis
- Understanding the redbanded stink bug's range fluctuations is crucial for predicting its impact as a pest, with its presence in Louisiana since 2000.
- Low winter temperatures affect the bug's survival, but the relationship between cold and other environmental factors on its spread is not fully understood.
- The study indicates that while extreme cold does limit its northward expansion, milder winters could lead to more stable populations, potentially increasing its threat to soybean crops in the Midsouth U.S.
Cold winter temperatures govern the distribution and abundance of many insect species, but refugia that provide microclimates can moderate temperature-driven mortality. Winter temperatures have been implicated in limiting the survival and range of Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae; redbanded stink bug), an economically damaging invasive pest in the southeastern United States, but the role of refugia in overwintering survival of this pest is poorly understood. We conducted 2 studies in successive years to evaluate how leaf litter from hardwoods, pines, and soybeans modulate overwintering site selection and survival of P.

Foliar applications of chlorantraniliprole were applied at four rates for leaves and two rates for petals and anthers at the second week of bloom.

- - Studies at the Delta Research and Extension Center focused on the effectiveness of chlorantraniliprole, a pesticide, on soybean leaves and florets during 2020 and 2021, applying it at various rates.
- - Leaf samples were taken from three different plant zones to analyze chlorantraniliprole concentrations and assess its effectiveness against corn earworm, showing over 71% control for up to 28 days.
- - The chlorantraniliprole was also found in soybean florets and could reduce corn earworm mortality by up to 48% for 14 days, suggesting continued use for effective pest control in soybeans.
Foliar-applied insecticide treatments may be necessary to manage thrips in cotton (Gossypium hirsutum L.) under severe infestations or when at-planting insecticide seed treatments do not provide satisfactory protection. The most common foliar-applied insecticide is acephate.
