Insect pests in Brassica napus crops: toward ecologically optimized integrated pest management

Pest Management Science, EarlyView.
Ecologically optimized IPM: Integrating landscape, biological, and chemical strategies for enhanced pest management. Key findings: Optimizing canola IPM requires the deliberate alignment of habitat diversification, behavioral conditioning, and evolutionary processes.

Mortality of native and invasive ladybirds co-infected by ectoparasitic and entomopathogenic fungi [PDF]

PeerJ, 2020
Harmonia axyridis is an invasive alien ladybird in North America and Europe. Studies show that multiple natural enemies are using Ha. axyridis as a new host.

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.

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.

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.

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.

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 ...

Actions on mammalian and insect nicotinic acetylcholine receptors of harmonine-containing alkaloid extracts from the harlequin ladybird Harmonia axyridis [PDF]

, 2020
The harlequin ladybird, Harmonia axyridis (H. axyridis), possesses a strong chemical defence that has contributed to its invasive success. Ladybird beetle defensive chemicals, secreted in response to stress and also found on the coating of laid eggs, are

Drought stress modulates indirect defense via bottom‐up effects in tomato and wheat

Pest Management Science, Volume 82, Issue 9, Page 8499-8511, September 2026.
Different water regimes can have a significant impact on plant morphology and defense pathways in tomato and wheat, triggering multiple olfactory choices in biocontrol agents of key insect pests. These findings could be used to implement biocontrol strategies within the IPM context under a changing climate scenario.

Identification of limonene as a potential kairomone of the harlequin ladybird Harmonia axyridis (Coleoptera: Coccinellidae)

European Journal of Entomology, 2010
Chemical cues involved in both host location and oviposition by Harmonia axyridis Pallas (Coleoptera: Coccinellidae) were investigated in laboratory and field experiments.
