Rolled Cardboard Makes a Handy Insect-Sampling Tool

A group of researchers gets creative with some simple materials: strips of cardboard, rolled up and tied with string. Affixed to tree trunks or limbs, the "trunk refugia" show promise as a simple and inexpensive tool for sampling tree-dwelling insects and arthropods.

tobacco hornworm - Manduca sexta

Advanced Morphology Techniques Reveal Tobacco Hornworm’s Secrets

Though studied for decades as a model organism, the tobacco hornworm's lack of silk production has never been thoroughly researched, until now. A team of researchers combining high-tech microscopic imaging with genomic techniques have captured in new detail the caterpillar's first instar silk-producing anatomy and subsequent loss of that capability as it molts to later instars.

Mexican fruit fly - Anastrepha ludens

For Mass-Rearing Sterile Fruit Flies, Fewer Males Means More Efficient Mating

Sometimes, less is more. Case in point: the mass-rearing program that produces millions of sterile Mexican fruit flies (Anastrepha ludens) for managing wild populations. Scientists refining the effort find that a lower ratio of males to females in mating cages leads to higher fecundity and fertility in the females—and higher cost-effectiveness for the operation.
