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]
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
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
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]
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.

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 ...
