Title: In situ liquid cell crystallization and imaging of thiamethoxam by helium ion microscopy

Abstract

Pest insect control is an essential component for crop protection and public health. Neonicotinoids are a relatively new class of insecticides developed in the last four decades. Thiamethoxam, a member of the neonicotinoid class, has shown outstanding potency for crop protection against a variety of piercing-sucking pests. However, its use in industrial-volume packing and transportation is complicated by crystallization dynamics. In this work, a helium ion microscope (HIM) with a Protochips liquid cell was utilized to crystallize and image thiamethoxam in situ. The results of the study illustrate the growth and morphology of the thiamethoxam crystals at different He⁺ exposure doses, which is markedly different from what has been typically observed. Energy-dispersive x-ray spectroscopy results confirm the presence of the thiamethoxam on the liquid cell membrane. This imaging study illustrates the HIM ability to image and induce the crystallization in soft materials in liquid environments, and attempts to shed light onto the key processes involved in liquid imaging.

Bacillus thuringiensisCry1Da_7 and Cry1B.868 Protein Interactions with Novel Receptors Allow Control of Resistant Fall Armyworms,Spodoptera frugiperda(J.E. Smith)

Journal Article Wang, Yanfei ; Wang, Jinling ; Fu, Xiaoran ; ... - Applied and Environmental Microbiology

Two new modified Bacillus thuringiensis (Bt) proteins, Cry1Da_7 and Cry1B.868, with activity against fall armyworms (FAW), Spodoptera frugiperda (J.E. Smith), were evaluated for their potential to bind new insect receptors compared to proteins currently deployed as plant-incorporated protectants (PIPs) in row crops. Results from resistant insect bioassays, disabled insecticidal protein (DIP) bioassays, and cell-based assays using insect cells expressing individual receptors demonstrate that receptor utilizations of the newly modified Cry1Da_7 and Cry1B.868 proteins are distinct from each other and from those of commercially available Bt proteins such as Cry1F, Cry1A.105, Cry2Ab, and Vip3A. Accordingly, these two proteins target different insectmore »« less

Atomic interactions of neonicotinoid agonists with AChBP: Molecular recognition of the distinctive electronegative pharmacophore

Journal Article Talley, Todd T ; Harel, Michal ; Hibbs, Ryan E ; ... - Proc. Natl. Acad. Sci. USA

Acetylcholine-binding proteins (AChBPs) from mollusks are suitable structural and functional surrogates of the nicotinic acetylcholine receptors when combined with transmembrane spans of the nicotinic receptor. These proteins assemble as a pentamer with identical ACh binding sites at the subunit interfaces and show ligand specificities resembling those of the nicotinic receptor for agonists and antagonists. A subset of ligands, termed the neonicotinoids, exhibit specificity for insect nicotinic receptors and selective toxicity as insecticides. AChBPs are of neither mammalian nor insect origin and exhibit a distinctive pattern of selectivity for the neonicotinoid ligands. We define here the binding orientation and determinants ofmore »« less

Allergy arising from exposure to airborne contaminants in an insect rearing facility: Health effects and exposure control

Technical Report Wolff, D

In agricultural crop improvement, yield under various stress conditions and limiting factors is assessed experimentally. Of the stresses on plants which affect yield are those due to insects. Ostrinia nubilalis, the European corn borer (corn borer) is a major pest in sweet and field corn in the U.S. There are many ways to fight crop pests such as the corn borer, including (1) application of chemical insecticides, (2) application of natural predators and, (3) improving crop resistance through plant genetics programs. Randomized field trials are used to determine the effectiveness of pest management programs. These trials frequently consist of randomlymore »« less

Insecticide Resistance Mechanisms in the Green Peach Aphid Myzus persicae (Hemiptera: Aphididae) I: A Transcriptomic Survey

Journal Article Silva, Andrea X. ; Jander, Georg ; Samaniego, Horacio ; ... - PLoS ONE

Background: Insecticide resistance is one of the best examples of rapid micro-evolution found in nature. Since the development of the first synthetic insecticide in 1939, humans have invested considerable effort to stay ahead of resistance phenotypes that repeatedly develop in insects. Aphids are a group of insects that have become global pests in agriculture and frequently exhibit insecticide resistance. The green peach aphid, Myzus persicae, has developed resistance to at least seventy different synthetic compounds, and different insecticide resistance mechanisms have been reported worldwide. Methodology/Principal Findings: To further characterize this resistance, we analyzed genome-wide transcriptional responses in three genotypes ofmore »« less

Insect control with $gamma$ rays

Conference Simon F, J E ; Srb, A M

The sterile insect release method (SIRM) for insect pest control with gamma radiation uses the insect pest to control itself. It provides the following advantages: where a pest insect is able to live or survive, the sterile insect will duplicate its behavior, therefore, there is no haven for the pest; the insect pest need not, reach a high population level, as is necessary before a system such as parasites and predators begins to work; and the sterile insects are able to mate with and decrease the population of only their own kind, thus the system is highly specific. Seven requirementsmore »« less
