Diapause in the pea aphid (Acyrthosiphon pisum) is a slowing but not a cessation of development [PDF]

BMC Developmental Biology, 2003
Many insects undergo a period of arrested development, called diapause, to avoid seasonally recurring adverse conditions. Whilst the phenology and endocrinology of insect diapause have been well studied, there has been comparatively little research into the developmental details of diapause. We investigated developmental aspects of diapause in sexually-

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.

Rhizobia–Bean Symbiosis Increases Root Herbivore Attraction and Growth via Volatile Signals and Enhanced Nutrition

Plant, Cell &Environment, Volume 49, Issue 7, Page 3952-3962, July 2026.
ABSTRACT The symbiosis between nitrogen‐fixing rhizobia and plants is considered mutually beneficial, yet its indirect effects on other organisms remain understudied. We examined how rhizobia symbiosis in Phaseolus vulgaris influences the behaviour and performance of Diabrotica balteata larvae. Specifically, we tested larval preference for nodulated (R+

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

Two Sphingomonas species modify the productivity and the susceptibility of Pisum sativum to pea aphid, Acyrthosiphon pisum

Plant Stress
Aphids are major pests of field crops, and their control still largely relies on chemical insecticides, which have significant ecological and health drawbacks.

Aphid alarm pheromone (E)‐β‐farnesene: mechanisms, applications, and challenges in pest management

New Plant Protection, Volume 3, Issue 2, June 2026.
This review highlights the advances in the application of the aphid alarm pheromone (E)‐β‐farnesene (EβF) for pest management. It focuses on smart delivery systems, molecular optimization, synthetic biology, and integration with digital agriculture. Additionally, it discusses key challenges and future directions for enhancing stability, field efficacy,

Native Regiella Endosymbionts Provide Strong Parasitoid Protection With Limited Impacts on Fitness and Virus Transmission in Myzus persicae

Environmental Microbiology, Volume 28, Issue 6, June 2026.
Native Regiella insecticola in Myzus persicae provides strong protection against parasitoid wasps but imposes only modest reproductive costs and does not affect virus transmission. Despite stable vertical and horizontal transmission, these effects alone do not explain the low natural prevalence of **Regiella** in field populations.
