Oxidative stress promotes pupation in some holometabolous insects. The levels of superoxide, a reactive oxygen species (ROS), are increased and superoxide dismutase 1 (BmSod1) and superoxide dismutase 2 (BmSod2) are decreased during metamorphic events in

Insect (Arthropoda: Insecta) Composition in the Diet of Ornate Box Turtles (Terrapene ornata ornata) in Two Western Illinois Sand Prairies, with a New State Record for Cyclocephala (Coleoptera: Scarabaeidae) [PDF]
A study of fecal samples collected over a two-year period from juvenile ornate box turtles (Terrapene ornata ornata Agassiz) revealed diets consisting of six orders of insects representing 19 families. Turtles were reared in captivity from eggs harvested

The mitochondrial genome of Aenasius arizonensis (Hymenoptera: Encyrtidae) with novel gene order
Aenasius arizonensis is the endoparasitoid of mealybug (Phenacoccus solenopsis) and plays an important role in biological control. We sequenced the A. arizonensis mitochondrial genome using next-generation sequencing.

Fast and robust learning by reinforcement signals: explorations in the insect brain [PDF]
We propose a model for pattern recognition in the insect brain. Departing from a well-known body of knowledge about the insect brain, we investigate which of the potentially present features may be useful to learn input patterns rapidly and in a stable ...

An inexpensive and portable microvolumeter for rapid evaluation of biological samples
We describe an improved microvolumeter (MVM) for rapidly measuring volumes of small biological samples, including live zooplankton, embryos, and small animals and organs.
