Hormone triggers moth mating

Studies have shown that most female moths looking for mates release a self-manufactured perfume, or sex pheromone, as soon as they emerge from the cocoon. Now scientists have found a moth, the true armyworm, that waits to mate until weather permits, thereby controlling the release of the sexy substance with a chemical system.

Canadian biologists Michel Cusson and Jeremy N. McNeil of Universite Laval in Sainte-Foy, Quebec, wanted to ...

Safer control of pests.(new pesticide)(Brief Article)
Chemistry and Industry ; A pesticide that works by preventing insects maturing looks like a potential candidate in the search for safer ways of controlling pests. The pesticide has been designed to attack insect juvenile hormone, which is essential in controlling the process of metamorphosis in insects' development. 'In
Beetle brains show how sex shortens life. (Tough Tradeoff).(Brief Article)
Science News ; Neurosurgery in beetles uncovers yet another way that having sex can make life shorter. Many insects and some other animals tend to die younger if they mate than if they don't, says Michael Siva-Jothy of the University of Sheffield in England. After 200 or so organ transplants in mealworm beetles,
The virtues of starvation. (insect pests) (Science and Technology)
The Economist (US) ; IF YOU want to dispose of an insect pest but do not want to spray noxious chemicals all over the place, you could try persuading the bug to starve itself to death. If the persuasion is genetic, it may even work. With such an idea in mind, a team at the Oxford Institute of Virology has developed a
Plant Sterilizes Female Grasshoppers
The Washington Post ; Sedge plants from Malaysia produce an insect hormone that sterilizes female grasshoppers that dare to feed on the plants, a team of Malaysian and U.S. scientists has discovered. The plant's defense mechanism, which evolved long ago, is identical to a strategy developed by biochemists a few years
ACTION OF MAJOR INSECTICIDE GROUPS ON INSECT CELL LINES OF THE BEET ARMYWORM, SPODOPTERA EXIGUA, COMPARED WITH LARVICIDAL TOXICITY
In Vitro Cellular & Developmental Biology ; SUMMARY In a first series of experiments, the biological response of a continuous cell line of the beet army worm, Spodoptera exigua, was tested with different groups of insecticides with different modes of actions: acetylcholinesterase inhibitors, acetycholine receptor agonists, inhibitors and
