Summary: This study found that the preferences of two predatory beetles for plant and plant/prey odors are influenced by innate recognition and recent dietary history, indicating some plasticity. The dietary history can lead the beetles to prefer the unconditioned plant/prey complex, which may be advantageous for generalist predators that frequently switch among different plants and prey types.

Summary: Insects such as lady beetles can ingest Cry proteins from genetically engineered crops without significant accumulation in their bodies, and the proteins are quickly degraded and excreted. The impact of Bt maize on lady beetle larvae and adults is minimal in terms of Cry protein exposure.

Summary: This study aimed to investigate whether cotton plants treated with potentially beneficial fungi affect the interaction between cotton aphids and predatory lady beetles. The results showed that the use of these fungal treatments had minor effects on lady beetle behavioral responses and would not strongly impact the predator-prey-plant interaction.

Summary: This study analyzes the ladybird beetle fauna of La Palma, one of the western islands of the Canary Islands. The survey recorded 26 species, including 7 new to La Palma and 2 new to the Canary Islands. The study confirms the frequent colonization of exotic ladybird species in the Canary Islands.

Summary: Ladybirds, one of the most diverse groups of beetles with over 6000 species globally, have their taxonomy and evolutionary history elucidated through sequencing nuclear protein-coding genes. The study identifies three subfamilies in Coccinellidae and suggests an Early Cretaceous origin for extant lady beetles. The rapid diversification of lady beetles in the Late Cretaceous is hypothesized to be driven by the boom of angiosperms which promoted the diversification of aphids, their prey.

Summary: Ladybird beetles Tenuisvalvae notata and Cryptolaemus montrouzieri are important predators of mealybugs, with their development and reproduction affected by temperature. Higher temperatures can shorten their developmental period while not significantly impacting female longevity or egg production. T. notata shows higher generation time and intrinsic rate of increase at 28 degrees C, and both species can complete more generations annually in locations with higher temperatures.

Summary: The paper provides an illustrated guide to the tribe Coccinellini of the Indian Subcontinent, including 119 species of 30 genera. Brief diagnostic descriptions and supporting illustrations are given for the genera and species, along with details of distribution, prey and plant associations, and seasonal occurrence. Life stage illustrations are included for 31 species to facilitate field identification of the immature stages.

Summary: Animals maintain physiological and behavioral systems to detect and consume specific nutrients, including sterols which are essential for survival. Lady beetles globally have a state-dependent sterol appetite to enhance fitness and can detect sterols pre-ingestion. Beetles across various clades maintain a state-dependent appetite for sterols, with the ability to taste them at concentrations as low as 1ppm.

Summary: The lady beetles Tenuisvalvae notata and Cryptolaemus montrouzieri exhibit cannibalism and intraguild predation behaviors in the absence of prey. C. montrouzieri has a clear advantage over T. notata, acting as the intraguild predator in over 80% of the interactions and preying more on T. notata larvae and eggs. There is also high cannibalism within species, posing a potential threat to the native T. notata. The interactions between these lady beetles could impact the success of biological control of mealybugs.

Summary: This article describes a previously unknown jumping behavior in beetle larvae, specifically Laemophloeus biguttatus. It was found that these larvae arch their bodies and grip the substrate before launching into the air by rapidly curling their bodies. The study also suggests that this jumping behavior is more efficient than crawling the same distance. By summarizing and discussing jumping behaviors in other insect larvae, the study provides a context for understanding this behavior in beetles.

Summary: This study investigated the sublethal effects of thiamethoxam on the offspring of the seven-spot ladybird beetle. The results showed that prolonged exposure to sublethal dosage of thiamethoxam had negative impacts on the life cycle, reproductive capacity, and population parameters of the ladybird beetle.

Summary: This study revealed that glyphosate can reduce the body weight of H. axyridis, although it does not significantly impact its survival rate and development duration. Glyphosate treatment significantly altered the abundance and gene copy number of dominant bacteria in the endosymbiont community of H. axyridis.

Summary: This study evaluated the predation potential of Thalassa montezumae, a predatory beetle, on the croton scale Phalacrococcus howertoni. The results showed that T. montezumae had a higher predation rate on nymphs compared to adults, and females chose prey faster than males. The acceptance level did not vary significantly between different stages of the prey.

Summary: The invasive pest Spodoptera frugiperda poses a major threat to agriculture in China. Experimental results suggest that Orius sauteri and Harmonia axyridis have the potential to control this pest through predation.
