DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima (Hemiptera: Reduviidae): Purification, bioinformatic analyses and the significance of its interaction with lipophorin in the internalization by developing oocytes [PDF]

open access: yes, 2018
DmCatD, a cathepsin D-like peptidase of the hematophagous insect Dipetalogaster maxima, is synthesized by the fat body and the ovary and functions as yolk protein precursor. Functionally, DmCatD is involved in vitellin proteolysis.

Patterns of morphological evolution in the raptorial appendages of praying mantises

open access: yesInsect Science, Volume 32, Issue 3, Page 1061-1079, June 2025.
This study traces changes in the morphology of the forelegs across fossil and extant dictyopterans to understand their evolution from cursorial limbs to the raptorial morphologies of mantodeans. Two new mantodean specimens preserved in amber are described herein.

Rewiring the Vehicle: Trypanosoma cruzi Parasites Alter the Antennae of Their Triatomine Hosts

open access: yesEcology and Evolution, Volume 15, Issue 3, March 2025.
Parasite Trypanosoma cruzi infects triatomine bugs. Infection induces antennal sensillum change in distribution and number in bugs. Antennal sensillum changes can make the bugs' search for food more efficient. ABSTRACT This study investigates the antennal phenotype of the kissing bug Triatoma pallidipennis (Stål), a primary vector of Chagas disease, by

Oviposition in the blood-sucking insect Rhodnius prolixus is modulated by host odors [PDF]

open access: yes, 2015
Background: Triatomine bugs are blood-sucking insects, vectors of Chagas disease. Despite their importance, their oviposition behavior has received relatively little attention. Some triatomines including Rhodnius prolixus stick their eggs to a substrate.

Novel use of a servosphere to study apodous insects: Investigation of blow fly post‐feeding larval dispersal

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 1, Page 14-21, March 2025.
A servosphere was used to record the speed, directionality and phototaxis of individual post‐feeding larvae of two species of blow fly (Diptera: Calliphoridae) on a smooth plastic surface over time. The servosphere rotates to compensate for the movement of an insect placed at its apex, thereby facilitating its unimpeded locomotion in any direction and ...

Trypanosoma cruzi infection enhances olfactory response in Triatoma pallidipennis Stål (Hemiptera: Triatominae) to compounds potentially useful for insect control

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 1, Page 160-170, March 2025.
Triatoma pallidipennis is one of the main vectors of Trypanosoma cruzi, the causative agent of Chagas disease. Attractant activity of octenol, nonanal and a mixture of lactic acid, hexanoic acid and ammonium hydroxide on T. cruzi–infected and non‐infected T. pallidipennis nymphal stages.

Spiders in a hostile world (Arachnoidea, Araneae) [PDF]

open access: yes, 2011
Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders.
