BACKGROUND Aquatic insects are very abundant and divers groups of insects that are associated with an aquatic or semiaquatic environment in one or more of their life stages. These insects have been, in some cases, well studied because they are vectors of several diseases. This is the first comprehensive faunistic study of aquatic insects from Babol County. The results may provide basic data for...

As American entomologists, we are often unaware of how insects are integrated into other cultures. In Asia, insects first appeared on traditional Chinese and Japanese ornamental artwork dating before 600 A.D. (Crambfrot, 1994). During the Meiji period (1868-1912), mushiya, or insect shops, sold collecting equipment and singing insects in cages (Laurent, 2001). Although there are no longer insec...

G. VOGEL’S NEWS STORY “FOR MORE PROTEIN, FILET OF CRICKET” (12 FEBRUARY, SPECIAL section on Food Security, p. 811) draws attention to the potential role of insects in food security. Although insects such as mopane worms and termites are widely consumed by some societies, especially in Africa (1–7), globalization and creation of a food culture based largely on Western values has led to their mar...

It is well known that insects, as a class, feed on an immense variety of different substances, and that each food has its specific insects. But it has never been explained whether, or to what extent, this relationship of insects and food is due to differences in the basic food requirements of different insects. In studying the dietetics of insects it was hoped to find an answer to the question:...

The caterpillar fungus Ophiocordyceps sinensis is one of the most valuable medicinal fungi in the world, and it requires host insects in family Hepialidae (Lepidoptera) to complete its life cycle. However, the genetic diversity and phylogeographic structures of the host insects remain to be explored. We analyzed the genetic diversity and temporal and spatial distribution patterns of genetic var...

flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biologicalinsects and useful for a wide range of tasks, including exploration, environmental monitoring, searchand rescue, and surveillance. recently, robotic insects driven by piezoelectric actuators have achievedthe important goal of taking off with external power; however, fully autonomous operation requir...

S insects have evolved audition and evasive behaviors in response to selective pressure from bats, and other insects were preadapted to detecting ultrasonic signals. Some bats have evolved in turn, improving the range or resolution of sonar signals and serendipitously making them less detectable by insects. In other words, there is a kind of evolutionary escalation going on between bats and ins...

Abtract: Interests in the permittivities of insects include data for radar applications in studying insect migration and for use in studies of dielectric heating for control of insects infesting cereal grains, wood products, and other materials. Sources of such data in the literature are identified, measurement data are presented, and dielectric properties data on insects are summarized in tabu...

MFÔs are a large diverse superfamily of enzymes found in all insect tissues. They are involved in the metabolism of xenobiotics (e.g. drugs, pesticides and plant toxins) and endogenous compounds (e.g. ecdysteroids and juvenile hormones). They are also involved in bioactivation of phosphorothioate compounds such as organophosphorus insecticides. They have very diverse activities like hydroxyla...
