Spectral Characterization of the Life Stages and Physiological Responses of Diatraea saccharalis Fabricius (Lepidoptera: Crambidae) Larvae Parasitized by Cotesia flavipes Cameron (Hymenoptera: Braconidae)

Entomologia Experimentalis et Applicata, EarlyView.
Hyperspectral proximal sensing was used to characterize the life stages and physiological responses of Diatraea saccharalis and to detect parasitism by Cotesia flavipes. Distinct spectral signatures differentiated eggs, larval instars, pupae, and adults, as well as live, dead, and parasitized larvae.

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.

Three new records of the genera Leiophron and Euphorus (Hym.: Braconidae: Euphorinae) from Iran [PDF]

نامه انجمن حشره‌شناسی ایران, 2013
The parasitoid wasps of the genera Leiophron Nees and Euphorus Nees were studied in northern Iran (Guilan, Mazandaran and Alborz provinces). The specimens were collected using Malaise traps from different habitats during 2010-2011.

Arthropod niche differentiation linked to grazing‐induced sward islets in intensively managed agricultural pasture

Insect Conservation and Diversity, EarlyView.
In a given number of samples, grassland sward islets contain more species of arthropods than the surrounding sward. When corrected for abundance, there is no difference in species richness, suggesting that the effect of islets might purely be to concentrate arthropods. The community structure differences indicated by non‐metric multidimensional scaling

A protracted phenology: Post‐diapause larval development of a threatened butterfly

Insect Conservation and Diversity, EarlyView.
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.

Insectary Plant Species Preferences of Predators and Parasitoid Families in a Mediterranean Horticultural Agroecosystem

Journal of Applied Entomology, EarlyView.
ABSTRACT The use of insectary plants to provide alternative food and shelter resources for enhancing natural enemy activity has been established as a common practice in IPM. Candidate flowering plant species have been screened and evaluated for their contribution to enhance life parameters of beneficial insects.

Causes of polymorphic melanism and its thermoregulatory function in a parasitoid wasp Meteorus pulchricornis (Hymenoptera: Braconidae)

European Journal of Entomology, 2013
We investigated the variation in body colour and its thermoregulatory function in Meteorus pulchricornis (Wesmael) (Hymenoptera: Braconidae), a parasitoid wasp of Spodoptera and other free-living lepidopteran larvae. We show that the body colour of adult

Towards an attract‐and‐reward strategy: evaluating nectar resources and HIPVs under laboratory conditions to enhance Aphelinus mali parasitism activity, a key parasitoid of Eriosoma lanigerum

Pest Management Science, Volume 82, Issue 4, Page 3955-3963, April 2026.
Euphorbia segetalis is a promising attractant insectary plant for Aphelinus mali. Meanwhile, Vicia faba and Vicia sativa are a promising nectar resource to sustain the parasitoid in early spring when the population of Eriosoma lanigerum is low, and honeydew is scarce.

Sex ratio shift caused by hyperparasitism in the solitary parasitoid Lysiphlebus hirticornis (Hymenoptera: Braconidae: Aphidiinae)

European Journal of Entomology, 2005
We examined the influence of offspring mortality caused by hyperparasitism on the secondary sex ratio of Lysiphlebus hirticornis Mackauer, a solitary endoparasitoid of the aphid Metopeurum fuscoviride Stroyan, in the field. Females of L.

Selective leaf surface defenses: trichomes trap herbivorous leafminers but spare parasitoid wasps

Pest Management Science, Volume 82, Issue 4, Page 4016-4025, April 2026.
Hooked trichomes on kidney bean leaves selectively entrap leafminer flies but rarely affect parasitoid wasps. This morphological barrier enables pest suppression with minimal impact on beneficial insects, offering insights for breeding pest‐resistant cultivars compatible with biological control. Abstract BACKGROUND Leafminers [e.g., Liriomyza trifolii (
