Slow and fast development in ladybirds: occurrence, effects and significance [PDF]
Web Ecology, 2012 Developmental and growth rates are known to vary in response to genetic, developmental, physiological and environmental factors. However, developmental variations that exist within a cohort under any constant rearing condition are not so well ...

The influence of age on reproductive performance of the predatory ladybird beetle, Propylea dissecta [PDF]
Journal of Insect Science, 2004 The influence of age on reproductive performance of an aphidophagous ladybird beetle, Propylea dissecta was examined using male and female beetles of varying ages (1-30 days) after a single mating stimulus.

Ultrastructural and Functional Organization of Maxillary Palps in Ladybird Species (Coleoptera: Coccinellidae) With Different Feeding Preferences. [PDF]
Microsc Res TechThis research described the ultrastructural organization of Coccinellidae maxillary palps. The apical sensory area housed the largest number of sensilla. The sensilla belonged to three types: uniporous, multiporous, and campaniform sensilla. Large number of sensilla and sensory neurons provide evidence that maxillary palps act as primary sensory organ ...

Mitogenomic Characterization and Phylogenetic Expansion of Tribe Coccinellini (Coleoptera: Coccinellidae) [PDF]
Ecol EvolThis study presents the complete mitochondrial genomes of nine ladybird species from the tribe Coccinellini and compares them with 58 previously published mitogenomes. Phylogenetic analyses confirm the taxonomic placement of these species within Coccinellini.

Sexual Dimorphism of Tarsal Attachment Devices and Their Relation to Mating in Coccinellidae. [PDF]
J MorpholWe explore the coevolution of male attachment devices and female elytral morphology in coccinellids. Specifically: (1) Disco‐setae are present in males of some species, located on the hairy pad which during mating hold on female elytra. (2) The area of male disco‐setae is extended when females have smooth elytra, and reduced when females have hairy ...

Unintended changes in transgenic maize cause no nontarget effects
Plants, People, Planet, 2022 Societal Impact Statement Genetic engineering is used to introduce new genes into plants to obtain crops with novel traits. However, the unintended effects of genetically engineered (GE) crops on nontarget organisms—such as beneficial insects—are a topic
