“…Random movement could result in diffusion distribution. Therefore, our results confirmed the wandering movement behavior of the adults of C. ferrugineus as reported in literature ( Anukiruthika et al 2021 ). Adults of rusty grain beetles move to grain with 10% CO 2 concentration and wet grain ( Parde et al 2004 ) and avoid higher than 42.5°C grain area ( Jian et al 2002 ).…”

“…Among the existing stored product insects, the rusty grain beetle [ Cryptolestus ferrugineus (Stephens) (Coleoptera: Laemophloeidae)] and red flour beetle [ Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae)] are mainly responsible for economic loss of stored wheat, especially in United States and Canada ( Anukiruthika et al 2021 ). Understanding the movement and distribution of insects helps us to develop a sampling plan, evaluate insect infestation rate, and conduct efficient storage management practices such as applying pesticides, leveraging monitoring tools, and properly specifying mathematical elements ( Jayas 1995 , Anukiruthika et al 2021 ). However, determination of insect behavioral response is quite complicated with varying storage conditions and changing biotic and abiotic factors.…”

“…The movement and distribution of stored product insects are affected by various biotic and abiotic factors and interactions among the factors ( Mason 2019 ). Factors mainly affecting insect movement and distribution are temperature, moisture, and carbon dioxide and their gradients, grain type, dockage, broken kernels, grain mass, insect density, age, life stage and sex, chemical compounds, fumigants, and species–species interactions ( Anukiruthika et al 2021 ).…”

“…Directional movement of insects was assessed in one-dimensional (1D) and two-dimensional (2D) grain mass. Insects have a bias diffusion under different temperature gradients, moisture differences, dockage levels, grain types and grain masses, time periods in relation with insect density, age, and temperature acclimation as summarized in a recent review on insect movement by Anukiruthika et al (2021) . Some of these studies focused on determination of the 1D vertical and horizontal movements of insects under a controlled linear temperature gradients ( Jian et al 2004a , 2005b ).…”

Understanding insect movement and distribution is critical for developing an effective insect pest management protocol. Movement and distribution of adult Cryptolestes ferrugineus (Stephens) in response to nominal temperature differences of 5, 10, 15, and 20°C in 1- and 2-m horizontal columns filled with 12.5% moisture content wheat were studied in 24, 48, and 72 h of movement times. In the wheat columns without temperature differences, adults had a diffusion distribution pattern caused by their random movement. Adults showed bias movement to the warmer grain in wheat columns with temperature differences and preferred the warmer grain regardless of the magnitude of temperature differences in less than 24 h. Their distribution did not have significant differences among different movement times in 1- or 2-m columns. About 40% of adults moved to the warmer wheat located at 0.4 to 0.5 m in the 1 m column but did not move to the warmer wheat located at 0.9 to 1 m in the 2-m column. Therefore, length of grain column influenced detection of warmer grain by insects. Adults under different temperatures had a similar response as that under linear temperature gradients.

Methyl Benzoate as a Promising, Environmentally Safe Insecticide: Current Status and Future Perspectives

The widespread use of synthetic chemical pesticides beginning in the late 1930s has contributed to the development of insecticide resistance of many important species of pest insects and plants. Recent trends in pesticide development have emphasized the use of more environmentally benign control methods that take into consideration environmental, food safety, and human health. Biopesticides (e.g., naturally occurring pesticidal compounds) are alternative pest management tools that normally have no negative impact on human health or the environment. Here we review methyl benzoate, a relatively new botanical insecticide that occurs naturally as a metabolite in plants, and whose odor is an attractant to some insects. Since 2016, many studies have shown that methyl benzoate is an effective pesticide against a range of different agricultural, stored product, and urban insect pests. Methyl benzoate has several important modes of action, including as a contact toxicant, a fumigant, an ovicidal toxin, an oviposition deterrent, a repellent, and an attractant. In this review, we summarize various modes of action of methyl benzoate and its toxicity or control potential against various kinds of arthropods, including agricultural pests and their natural enemies, and pollinators. We conclude that methyl benzoate is a very promising candidate for use in integrated pest management under either greenhouse or field conditions.
