Effects of temperature on sexual competition in three kelp species, Pterygophora californica, Nereocystis luetkeana, and Macrocystis pyrifera: Implications for range shifts in foundation species

Phycological Research, EarlyView.
SUMMARY Kelp forests are threatened by rising ocean temperatures. However, the effects of warming on early life stage interactions among co‐occurring kelp species, particularly competitive dynamics and reproductive timing, remain poorly understood. This study investigates the effects of temperature on embryonic sporophyte competitive interactions and ...

Ant trail pheromone biosynthesis is triggered by a neuropeptide hormone.

PLoS ONE, 2012
Our understanding of insect chemical communication including pheromone identification, synthesis, and their role in behavior has advanced tremendously over the last half-century.

Seeing Through an Ant's Eyes: Do Entomopathogenic Fungi Extend Their Cognition to Their Hosts?

Topics in Cognitive Science, EarlyView.
Abstract Post‐cognitivist approaches recognize cognition as a phenomenon that involves not just brains but all the sensorimotor apparatus of organisms. This means that brains are not always required for the emergence of cognition and that every organism can, in principle, be cognitive, unlocking a theoretical framework to explain the complex adaptive ...

A predicted sex pheromone receptor of codling moth Cydia pomonella detects the plant volatile pear ester

Frontiers in Ecology and Evolution, 2014
Plant volatiles mediate host discrimination and host finding in phytophagous insects. Understanding how insects recognize these signals is a current challenge in chemical ecology research. Pear ester, ethyl (E,Z)-2,4-decadienoate, is a powerful, bisexual

Sex‐Specific doublesex Regulation Targeting the Color‐Patterning Gene h Underlies the Evolution of Wing Sexual Dimorphism in the Harlequin Ladybug Harmonia axyridis

Evolution &Development, Volume 28, Issue 1, March 2026.
doublesex regulates sexual dimorphism in elytral color patterns of Harmonia axyridis by downregulating the color patterning gene h in males. This regulatory link diverged in derived color morphs, coinciding with the loss of sex‐specific elytral color patterns.

Effects of Different Combinations of Sterile and Fertile Thaumatotibia leucotreta on Fruit Infestation and Population Growth Rate

Journal of Applied Entomology, Volume 150, Issue 2, Page 137-146, March 2026.
ABSTRACT Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae) is a key phytosanitary pest of citrus in South Africa. The pest damages fruit by burrowing and feeding on the pulp, thus causing yield losses and export rejections. There are several T. leucotreta management strategies, such as orchard sanitation, mating disruption, attract‐and‐kill,

A Volatile Cue From a Specialist Herbivore Primes Gene Expression Against Biotic Stress in Tall Goldenrod (Solidago altissima L.)

Plant, Cell &Environment, Volume 49, Issue 3, Page 1424-1438, March 2026.
ABSTRACT Insect‐derived molecular cues can prime plant defences against herbivore attack. The genes that are sensitive to priming, and how their expression changes on the scale of days, have not been fully resolved. Moreover, priming may affect interactions with insects that are not the source of the priming cue.

Synthetic Sex Pheromone in a Long-Lasting Lure Attracts the Visceral Leishmaniasis Vector, Lutzomyia longipalpis, for up to 12 Weeks in Brazil

PLoS Neglected Tropical Diseases, 2014
Current control methodologies have not prevented the spread of visceral leishmaniasis (VL) across Brazil. Here, we describe the development of a new tool for controlling the sand fly vector of the disease: a long-lasting lure, which releases a synthetic ...

Ips acuminatus (Gyllenhal) in the Czech Republic: Flight dynamics and adult population structure

Physiological Entomology, Volume 51, Issue 1, Page 136-146, March 2026.
Ips acuminatus exhibits a univoltine life cycle in Central Europe and no full second generation in midsummer. The sex ratio shifts from male‐biased in spring to slightly female‐biased with the season, with over 90% of females mated. Among the pheromone lures tested, the ACP was most attractive, and combining ACP and PH lures could be used for effective

Do male-derived substances affect female mating receptivity and release of sex pheromone by females of the sorghum plant bug Stenotus rubrovittatus (Hemiptera: Miridae)?

European Journal of Entomology, 2014
In insects, male-derived substances transferred during copulation often alter female physiology. Thus these substances may affect female behaviour, including mating receptivity and release of sex pheromone. In the sorghum plant bug Stenotus rubrovittatus
