Resource Availability Overrides Predator Presence in Mosquito Oviposition Habitat Selection

Entomologia Experimentalis et Applicata, EarlyView.
Gravid Culex quinquefasciatus balance predation risk against resource availability when selecting oviposition sites. In outdoor mesocosms, we factorially manipulated sugarcane jaggery (resource) and notonectid predators (adult vs. nymph; caged vs. free‐swimming) across 2 years.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

Ecological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

The orientation of Tribolium castaneum adults in the presence of aggregation pheromone 4,8-Dimethyldecanal and food oils

Julius-Kühn-Archiv, 2018
Monitoring of Tribolium castaneum, the red flour beetle, involves the use of aggregation pheromone 4,8- dimethyldecanal (4,8 DMD) and kairomones such as cereal oils.

Visual Cues Can Alter the Behavioural Responses of Dragonfly Larvae to Chemical Alarm Cues

Ethology, EarlyView.
Using a controlled experimental approach, we examined how chemical and visual cues influence antipredator behaviour in Aeshna cyanea larvae and tested whether risk‐related information can be socially transmitted among nearby conspecifics. Our results show that dragonfly larvae do not copy the antipredator responses of others, but visual cues alter how ...

Size‐specific reduction in kelp consumption by New Zealand urchins exposed to chemical cues from the red rock lobster

Ecosphere
Sea urchins can strongly reduce their mobility, exposure to predation, and feeding rates upon detection of chemical cues produced by predators, driving behavioral effects on grazing activity that may contribute to macroalgal community dynamics.

Ecological and evolutionary factors of intraspecific variation in inducible defenses: Insights gained from Daphnia experiments

Ecology and Evolution, 2020
Phenotypic variation among individuals and species is a fundamental principle of natural selection. In this review, we focus on numerous experiments involving the model species Daphnia (Crustacea) and categorize the factors, especially secondary ones ...

Diel vertical migration strategies of zooplankton in oligotrophic Russell Pond, New Hampshire [PDF]

, 2014
Russell Pond is an ultra-oligotrophic lake with low chlorophyll a (1.9 mg L-1), total phosphorus (3.4 mg L-1), high Secchi Disk (10.4 m) and high light transmission (water coefficient of water, kw=0.33). Vertical migration of Chaoborus, Bosmina, Daphnia,

Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, EarlyView.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...

Chemical ecology of egg parasitoids associated with true bugs [PDF]

, 2012
Parasitoids representing some 15 families of Hymenoptera develop in insect eggs; three of these families, Platygastridae (= Scelionidae), Mymaridae, and Encyrtidae, are associated with Heteroptera.
