Elevated nitrogen deposition protects an invasive plant from herbivory through altering leaf volatile‐mediated tritrophic interactions

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Atmospheric nitrogen deposition disrupts plant–herbivore interactions, but its impact on leaf volatile organic compounds (VOCs)‐mediated multi‐trophic herbivore resistance remains unclear within the context of plant invasion. In this study, we initially investigated the

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.

Coat of many colours: colour pattern polymorphism and invasion by the harlequin ladybird Harmonia axyridis [PDF]

, 2012
The invasive alien harlequin ladybird, Harmonia axyridis, is a polymorphic species. Melanic and non-melanic individuals can be found in Britain. The UK Ladybird Survey receives occurrence records of H.

Reduced fertilization regimes could boost biocontrol service without reducing crop yield

Insect Science, EarlyView.
Fertilization level influences pest control effectiveness in tomato crops. High fertilization increases plant growth and aphid density but reduces the performance of the parasitoid Aphidius ervi. In contrast, the predator Adalia bipunctata maintains consistent aphid suppression regardless of fertilization regime.

Beetlehangers.org: harmonizing host–parasite records of Harmonia axyridis and Hesperomyces harmoniae [PDF]

Arthropod-Plant Interactions
AbstractCitizen 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 ...

Impact of food scarcity on the foraging dynamics of Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae) Impacto da escassez de alimentos na dinâmica de forrageamento de Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae)

Agricultural and Forest Entomology, EarlyView.
Starvation duration alters predatory behaviour of Eriopis connexa, affecting aphid consumption and survival dynamics. Increased starvation enhances attack rate, accelerating prey depletion without substantially affecting handling time. Functional response remains type II, with stronger predation under prolonged food deprivation.

A Smelly Conflict: The Role of Olfactory Information in the Interaction of Insect Herbivores and Their Natural Enemies

Entomologia Experimentalis et Applicata, EarlyView.
Insect herbivores rely on olfactory cues to locate natural‐enemy‐free spaces for feeding or ovipositing; conversely, natural enemies detect herbivores by chemical cues from damaged plants or from the herbivores themselves. Based on the reviewed findings, we suggest that herbivores and natural enemies converge towards using specific olfactory cues. This

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

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.

Decline in native ladybirds in response to the arrival of Harmonia axyridis: early evidence from England

, 2011
1. Harmonia axyridis (Coleoptera: Coccinellidae) is an invasive nonnative ladybird in Europe, where it was introduced as a biological control agent of aphids and coccids. 2.
