Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae

Pest Management Science, EarlyView.
Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.

EFFECT OF GAMMA IRRADIATION ON PRODUCTION AND PERCEPTION OF SEX PHERMON IN THE BLACK CUTWORM, Agrotis ipsilon (HUFN) [PDF]

Journal of Plant Protection and Pathology, 2007
The females of the black cutworm, Agrotis ipsilon ( Hufn), produce their sex pheromone early at the beginning of their emergence. Males also can percept this pheromone at the same age.

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Dolichodial: a new aphid sex pheromone component?

, 2008
The sex pheromones of many aphid species from the subfamily Aphididae comprise a mixture of the iridoids (cyclopentanoids) (1R,4aS,7S,7aR)-nepetalactol and (4aS,7S,7aR)-nepetalactone.

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Ostrinia revisited: Evidence for sex linkage in European Corn Borer Ostrinia nubilalis (Hubner) pheromone reception

BMC Evolutionary Biology, 2010
Background The European Corn Borer, Ostrinia nubilalis (Hubner), is a keystone model for studies on the evolution of sex pheromone diversity and its role in establishing reproductive isolation. This species consists of two sympatric races, each utilizing

Offspring performance does not explain oviposition preference in the leafminer Stigmella sorbi (Lepidoptera: Nepticulidae): a tri‐trophic perspective

Insect Science, EarlyView.
We studied oviposition site selection in a leaf‐mining moth (Stigmella sorbi) on rowan trees (Sorbus aucuparia) in northwestern Russia, assessing larval performance across different shoot types, leaf positions, and leaflets. Larval survival was highest on long vegetative shoots, yet females showed no preference for these optimal sites.

Effectiveness of Various Solar Light Traps With and Without Sex Pheromone for Mass Trapping of Tomato Leaf Miner (Tuta absoluta) in a Tomato Field

Notulae Scientia Biologicae, 2018
Tuta absolute was a quarantine pest in Iran that has been recorded for the first time in 2009. The most conventional methods for control of this pest in Iran are chemical methods and mass trapping, although the efficiency of the latter method is not ...

Identification and Functional Characterization of Two Putative Pheromone Receptors in the Potato Tuber Moth, Phthorimaea operculella

Frontiers in Physiology, 2021
Pheromones are a kind of signal produced by an animal that evoke innate responses in conspecifics. In moth, pheromone components can be detected by specialized olfactory receptor neurons (OSNs) housed in long sensilla trichoids on the male antennae.

Potential application of the bumblebee foraging recruitment pheromone for commercial greenhouse pollination [PDF]

, 2009
Commercial bumblebee colonies are important crop pollinators. Here we assess whether application of artificial foraging recruitment pheromone can increase foraging activity in Bombus terrestris colonies on a relevant timescale for commercial pollination.
