Defensive Symbiont Genotype Distributions Are Linked to Parasitoid Attack Networks. [PDF]

Ecol Lett
Facultative symbionts are widespread in arthropods and can provide important services such as protection from natural enemies. Yet what shapes defensive symbiont associations in nature remains unclear. We show that the symbiont Hamiltonella defensa's genotype distribution strongly aligns with sharing the same parasitoids, rather than host plants ...

Toxins for Transgenic Resistance to Hemipteran Pests [PDF]

, 2012
The sap sucking insects (Hemiptera), which include aphids, whiteflies, plant bugs and stink bugs, have emerged as major agricultural pests. The Hemiptera cause direct damage by feeding on crops, and in some cases indirect damage by transmission of plant ...

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, EarlyView.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

The effects of six species of aphids on some life history parameters of the ladybird Propylea quatuordecimpunctata (Coleoptera: Coccinellidae)

European Journal of Entomology, 2005
One of the factors affecting the effectiveness of predatory coccinellids in an aphid infested crop is the food specificity of the predator. The response towards six species of aphids (Sternorrhyncha: Aphididae) was therefore tested in one of the most ...

FUNCTIONAL RESPONSE OF Nabis punctipennis Blanchard to Acyrthosiphon pisum Harris IN THE LABORATORY [PDF]

Chilean journal of agricultural & animal sciences, 2017
ABSTRACT This study analyzed the predatory behavior of adult females of Nabis punctipennis Blanchard (Nabidae) towards Acyrthosiphon pisum Harris (Aphididae) in the laboratory in order to determine its functional response and potential as a biological control agent of this aphid. Both hemipterans are common in alfalfa, Medicago sativa L., in Chile. The

The Australian Crop Mirid, Sidnia kinbergi Stål (Hemiptera: Miridae): Lifecycle, Agricultural Impact and Management

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT The Australian Crop Mirid (ACM), Sidnia kinbergi Stål (Hemiptera: Miridae), is highly polyphagous and is endemic to Australia. It is widely distributed across Australia and New Zealand and feeds on a wide range of agricultural crops. ACM has traditionally been a pest of forage crops and legumes but has recently emerged as a key pest of several

Preliminary Functional Group Patterns of Arthropods in a Maize Field and Adjacent Cultivated Refuge Strip in South Africa

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT Agricultural intensification is a major driver of global arthropod declines. Habitat management strategies, such as cultivated refuge strips (CRS), can counteract these effects by enhancing biodiversity, promoting conservation biological control and improving agroecosystem resilience.

Identification of potential predators of western bean cutworm (Striacosta albicosta) in field corn through molecular gut‐content analysis

Entomologia Experimentalis et Applicata, Volume 173, Issue 11, Page 1165-1176, November 2025.
The noctuid pest western bean cutworm (Striacosta albicosta) lays its eggs in corn fields over the season. Various generalist predators consume the eggs and larvae of this pest. To improve integrated pest management of S. albicosta, this study identified key trophic interactions between S. albicosta and predatory arthropods in corn fields.

Leucopis annulipes larvae (Diptera: Chamaemyiidae) use a furtive predation strategy within aphid colonies

European Journal of Entomology, 2008
A laboratory experiment was conducted to determine whether the predation strategy of larvae of the aphidophagous silver fly Leucopis annulipes Zetterstedt (Diptera: Chamaemyiidae) is furtive, as are larvae of the aphidophagous midge Aphidoletes ...
