A sex-linked locus controls wing polymorphism in males of the pea aphid, Acyrthosiphon pisum (Harris) [PDF]

Heredity, 2002
Discrete variation in wing morphology is a very common phenomenon in insects and has been used extensively in the past 50 years as a model to study the ecology and evolution of dispersal. Wing morph determination can be purely genetic, purely environmental, or some combination of the two. The precise genetic determinants of genetically based wing morph

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, Volume 150, Issue 8, Page 1102-1114, September 2026.
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 ...

Insects and Survival: A Review of Primary and Secondary Defense Strategies

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
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.

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 ...

Bacteriophages in the Rhizosphere: Roles in Nutrient Cycling, Bacterial Community Structure, and Animal‐Mediated Dispersal

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
This review discusses bacteriophages' roles in soil ecosystems, highlighting their impact on nutrient cycling, plant health, and soil remediation, as well as animal‐mediated phage dispersal mechanisms. Overall, while bacteriophages have potential biotechnological applications, their negative effects on microbial functions and nutrient cycling highlight

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

Potential use of a serpin from Arabidopsis for pest control. [PDF]

PLoS ONE, 2011
Although genetically modified (GM) plants expressing toxins from Bacillus thuringiensis (Bt) protect agricultural crops against lepidopteran and coleopteran pests, field-evolved resistance to Bt toxins has been reported for populations 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.

Discharge of Conidia of Entomophthora thaxteriana Petch from the Pea Aphid Acyrthosiphon pisum Harris [PDF]

Journal of General Microbiology, 1971
SUMMARY: At 21°, conidia of Entomophthora thaxteriana were first discharged from infected pea aphids about 6 to 9 h. after the aphids died and the rate of discharge was highest during a short period about 9 h. later. In constant light, the rate then decreased and discharge ended about 36 h. after an infected aphid died; in constant darkness the maximum
