Effects of non‐host traces on behavioural responses of an egg parasitoid to substrate‐borne semiochemicals in a multi‐herbivore scenario

Ecological Entomology, EarlyView.
In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces

Preference‐performance relationship in the thistle tortoise beetle: Implications for its realised host range

Ecological Entomology, EarlyView.
There was a positive relationship between adult preference and larval performance. However, the strength of the relationship ranged from weak to strong depending on the measure of adult preference. The adult beetle showed substantial flexibility in host plant selection and equal performance across most thistle hosts.

The effect of caste, mass and colony identity on rescue priorities in the red imported fire ant

Ecological Entomology, EarlyView.
Fire ants will rescue brood when the brood becomes trapped underground. We find that rescuers may use odor cues to locate trapped rescue targets. We demonstrate that a single reproductive larva is preferentially rescued over a single worker larva, but that caches of multiple worker larvae receive equal treatment as a single reproductive larva.

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

Ecological Entomology, EarlyView.
Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

Leaders Are Somethin' Else: Behavioural Variation Associated With Roles During Tandem Running Recruitment

Ethology, EarlyView.
In this study, we found moderate to strong repeatabilities in behavioural variables measuring the personality traits: activity, aggressiveness and exploration. Similarly, the probability of acting as a leader during tandem running in an emigration event was moderately (R = 0.469) repeatable.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

The FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Conifer host identity shapes wood‐boring beetle communities more than climate across a latitudinal forest gradient in Quebec (Canada)

Insect Conservation and Diversity, EarlyView.
Host tree identity and latitude shaped wood‐boring beetle assemblages, with species richness declining northward but community composition varying among regions and hosts. Host tree species influenced beetle communities more strongly than climate; black spruce supported the most species, while eastern hemlock hosted very few.

Dead wood retention and the risk of bark beetle attack [PDF]

, 2002
Wind-felled Norway spruce trees left for conservation purposes and spruce stems stored as forest fuel may be colonised by the bark beetles Ips typographus and Pityogenes chalcographus (Coleoptera: Scolytidae).
