Are we underestimating the diversity and incidence of insect bacterial symbionts? A case study in ladybird beetles

open access: yes, 2007
Vertically transmitted bacterial symbionts are common in arthropods. However, estimates of their incidence and diversity are based on studies that test for a single bacterial genus and often only include small samples of each host species.

Diet and chemical defence in ladybird beetles (Coleoptera: Coccinellidae)

open access: yes, 2022
In this paper, I review the effects of the diet of ladybirds on chemical defence in this group of beetles. The tendency to refl ex bleed and the diversity of autogenously produced alkaloids in different taxa may be evolutionarily related to diet and the ...

Condition-dependent ejaculate size and composition in a ladybird beetle [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2010
Sexually selected male ejaculate traits are expected to depend on the resource state of males. Theory predicts that males in good condition will produce larger ejaculates, but that ejaculate composition will depend on the relative production costs of ejaculate components and the risk of sperm competition experienced by low- and high ...

Ladybird Beetles and Aphid Control [PDF]

open access: yes, 1949
The author discusses Ladybird beetles long recognized as beneficial insects which largely feed largely upon aphids. An examination on June 24 of a late seeding of wheat, infested with greenbugs, (aphids) near Fargo showed ladybird beetles to be present

Ecology and evolution of pyrazines in insects

open access: yesBiological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Area‐restricted search under realistic constraints

open access: yesOikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Microbiome‐mediated chemical communication in insects: Implications for pest management

open access: yesPest Management Science, EarlyView.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐
