Ovipositional Behavior Of The Twig Girdler (Cerambycidae: Oncideres Cingulata) On Stems Of Mockernut Hickory (Carya Tomentosa) In Arkansas, R. Tumlison, L. Serviss

Journal of the Arkansas Academy of Science

The Twig Girdler (Cerambycidae: Oncideres cingulata) is a long-horned beetle that girdles stems of certain species of trees to prepare a habitat for its offspring. The stems eventually die, break, and fall from the tree, but the beetle usually had already laid its eggs within the stems. Eggs are laid singly, almost always at growth rings or leaf bases. Because the space for the young to develop is finite, laying too many eggs could cause reproductive failure and too few eggs would be suboptimal. We hypothesized that the female laying eggs should be able to evaluate the stem and …

However, tallgrass prairies are considered endangered ecosystems, particularly in the Ozark Highlands and Grand Prairie regions of Arkansas, where less than 0.05% of the state's original prairie land area remains. Understanding soil nutrient supplies over time in native tallgrass prairie ecosystems is critical for quantifying the success of restoration and rehabilitation activities. The objective of this study was to evaluate the effects of soil moisture regime (SMR) (i.e., aquic and udic), region (i.e., Ozark Highlands and Grand Prairie), and their …

Functional Characterization Of The Reniform Nematode Effector Protein Rr6640 In Soybean Parasitism, Noah Solomon

2026 Research Poster Competition

Reniform nematode (Rotylenchulus reniformis, RN) is a major plant-pest affecting key crops in Arkansas such as cotton and soybean, causing economic losses exceeding $757 million in the U.S. over the past decade. While some genetic resistance exists in cotton, soybean remains highly susceptible, exacerbating RN populations in crop rotations. To address this gap, this research investigates the mechanisms of nematode infection focusing on effectors, the specialized proteins secreted by the parasite to manipulate host cell biology and suppress plant immunity. This study characterizes Rr6640, a putative effector gene identified as an ortholog to a virulence factor in the Beet Cyst …
