Summary: Global climate change leading to more arid weather will have a significant impact on agriculture, affecting the interactions between potato, Leptinotarsa decemlineata, and Arma chinensis. Drought was found to crucially affect potato growth and yield, as well as the growth and reproduction of L. decemlineata, while also significantly reducing the longevity and survival rate of A. chinensis adults.

Summary: This study evaluated the resistance of seven potato cultivars to the Colorado potato beetle by measuring bio-physiological aspects. The results showed that the Manitou cultivar exhibited the highest resistance to the pest, with lower bio-physiological parameters compared to other cultivars. The Manitou cultivar could be a potential candidate for integrated pest management programs.

Summary: The study investigated the effect of white bean and rapeseed protein extracts on digestive alpha-amylase gene expression of the Colorado potato beetle. The results showed significant inhibitory effects of these protein extracts on the third and fourth instar larvae, leading to considerable mortality. These plant proteins may disrupt the insect's digestive physiology to control this crucial potato pest.

Summary: The essential oils from Tanacetum parthenium and Tanacetum vulgare have demonstrated antifeedant activity against Colorado potato beetles, with parthenium being more effective against larvae and vulgare more effective against adults. The concentration of the essential oils significantly influenced the behavior of the beetles, with higher concentrations resulting in quicker avoidance of treated leaf discs. This suggests potential for the use of these oils as a potato protection strategy.

Summary: The study reveals a group of genetic coding genes associated with pestiferousness in the Colorado potato beetle lineage, involved in biological processes such as xenobiotic detoxification, chemosensation, and hormone function.

Summary: The microbial communities of the Colorado potato beetle from different geographical sources in China showed significant differences, with Pseudomonas being the unique dominant microorganism in Heilongjiang Province and several common dominant bacteria shared between Xinjiang Uygur Autonomous Region and Heilongjiang Province. Diversity of bacterial communities in CPB was higher in Urumqi, Jimunai, and Wenquan regions. tSNE analysis indicated that order and genus were suitable taxonomic levels to distinguish the geographical sources of CPB.

Summary: This study compared the activity of four insecticides among different CPB strains, with abamectin showing the highest activity against all three CPB strains. However, no differences were observed between the dsRNA-resistant and susceptible CPB strains for any of the tested compounds. Overall, these results indicate a lack of cross-resistance to commonly used chemical insecticides in the dsRNA-resistant CPB strain.

Summary: This study investigated the molecular and biochemical properties of two acetylcholinesterases (LdAChE1 and LdAChE2) from the Colorado potato beetle. The results showed that LdAChE1 exists in a soluble form, while LdAChE2 exists in both soluble and amphiphilic forms. LdAChE2 has a higher catalytic efficiency and is more sensitive to insecticides compared to LdAChE1. The soluble LdAChE1 may function as a bioscavenger, while LdAChE2 may be the main enzyme for synaptic transmission.

Summary: The intercrop patterns of potato and safflower can significantly reduce the density and damage index of the Colorado potato beetle, while increasing the biodiversity and abundance of predators. Intercropping also leads to additional yield profits. The study suggests that 4P:4S and 4P:8S are effective in controlling the Colorado potato beetle in potato fields.

Summary: This paper presents a method for monitoring and recognizing the development stages of the Colorado beetle in potato crops using multispectral and color cameras. The method involves real-time analysis of gathered images from camera sensors attached to tractors or unmanned aerial vehicles. An artificial neural network classification method for identifying larvae in the images is also discussed.

Summary: In this study, it was found that the expression levels of Ld & alpha;3, Ld & alpha;8 and Ld & beta;1 were significantly decreased after treatments with thiamethoxam and imidacloprid. Furthermore, RNA interference also reduced the susceptibility of Colorado potato beetles to these insecticides.

Summary: Crop switching is an important strategy to address climate change, but it is necessary to consider pest management when introducing new crops. Potato farming in the Philippines is being scaled up to meet the needs of a growing population. In this paper, a graph theoretic model is developed to assess pest management options for the potential entry of the Colorado potato beetle in potato farms in the Philippines. The use of biological control agents outperforms chemical pesticides, but the concurrent use of both agents may be less effective.

Summary: The study evaluated the pathogenicity of 14 Turkish isolates of Beauveria bassiana against different stages of Colorado potato beetle, showing high virulence in causing mortality in both larvae and 0-48-h-old adults. Molecular phylogenetic analyses indicated a high similarity of these isolates with other B. bassiana isolates in GenBank. Further field tests are recommended to validate the laboratory results.
