Insects and Survival: A Review of Primary and Secondary Defense Strategies
Entomologia Experimentalis et Applicata, EarlyView.Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.

Beetlehangers.org: harmonizing host–parasite records of Harmonia axyridis and Hesperomyces harmoniae [PDF]
Arthropod-Plant InteractionsAbstractCitizen science is an increasingly powerful tool to gather large quantities of biological data and to engage the public. The number of citizen science initiatives has rapidly increased in the last 15 years. Invasive alien species such as the harlequin ladybird, Harmonia axyridis (Coleoptera, Coccinellidae), provide a particularly good ...

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.
