Host Detection by Cuckoo Bumblebees: Choice Experiments Reveal Non‐Visual Cues Support Host Detection, but Accuracy Is Low

Entomologia Experimentalis et Applicata, EarlyView.
Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.

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

Disposição e morfologia externa dos pêlos de uma lontra fêmea da espécie Lutra longicaudis (Olfers, 1818) (Carnivora, Mustelidae).

Biotemas, 2007
Estudaram-se os pêlos de um espécime de lontra (Lutra longicaudis) observando-se os seguintes parâmetros: tamanho, forma, número, camadas e distribuição dos pêlos na pele, e os aspectos microscópicos da cutícula, córtex e medula do pêlo.

Mecanismos moleculares involucrados en la esclerotización de la cutícula de los insectos

1- Se describió el primer mutante de insectos que falla en la exportación de materiales desde la epidermis hacia el exoesqueleto cuticular. 2- Se logró medir por primera vez la actividad de una nueva enzima, la N-β-alanildopamina sintetasa, y se avanzó ...

Maternal factors from a parasitoid wasp mediate hyperparasitoid attraction to parasitized caterpillars

Ecological Entomology, EarlyView.
The parasitoid‐associated polydnavirus CgPDV, but not venom alone, significantly increases the attractiveness of Pieris brassicae caterpillars to the hyperparasitoid Baryscapus galactopus at close range. Naturally parasitized caterpillars elicit stronger hyperparasitoid attraction than any injection treatment, indicating that additional factors beyond ...

Efecto del tratamiento hidrotérmico sobre la ultraestructura de la cutícula del fruto de mango | Effect of hydrothermal treatment on the ultrastructure of cuticle of mango fruit [PDF]

, 2018
La cutícula es importante en la fisiología de los vegetales porque actúa como primera interacción entre la planta y el ambiente. Su integridad es afectada por factores genéticos, ambientales, fisiológicos y de manejo, tanto en campo como en poscosecha ...

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.

Microbiome‐mediated immunity: Limited support from the gazelle dung beetle

Ecological Entomology, EarlyView.
Digitonthophagus gazella rely on a maternally inherited microbiome passed across generations via a maternal faecal pellet called the pedestal. We experimentally manipulated the presence of the pedestal, providing it to some individuals while withholding it from others to determine how pedestal microbiota may affect beetle immune potential.
