What determines body size?
How does a growing organism determine what its final body size will be? In the moth Manduca sexta, also known as the tobacco hornworm and recognisable by its distinctive blue-green caterpillar, adult body size is largely determined at the end of larval life, when the caterpillar has reached it final weight and is about to metamorphose into a moth. view more (2006-08-02)
Multivariate coupling mechanism of superhydrophobicity on NOCTUIDAE moth wing surface
Research carried out by Key Laboratory for Terrain Machine Bionics Engineering of Ministry of Education, Jilin University in Changchun, China, has shown that the co-coupling effect of scale biomaterial, micron-class shape and nanometer-class structure of vertical gibbosities of scale can induce surface hydrophobicity and self-cleaning function of... view more...

Biologist discovers pink-winged moth in Chiracahua Mountains
University of Arizona biologist Bruce Walsh has identified a new species of moth in southern Arizona. Normally, this is not a big deal. view more (2009-06-10)
University invention enlisted in battle against the brown-tailed moth
An environmentally friendly insect trap devised by researchers at the University of Southampton is the latest weapon in Portsmouth City Council's long-running battle to control infestations of the caterpillars of the brown-tailed moth. view more (1998-09-04)
Edge density key to controlling gypsy moth spread
Controlling population peaks on the edges of the gypsy moth range may help to slow their invasion into virgin territory, according to a team of researchers. view more (2006-11-16)
Which came first, the moth or the cactus?
It's not a good idea to put all your eggs in one basket- unless you're a senita moth. view more (2007-08-15)
New moth variety disarms plants guarded by selenium
In new work, researchers report that the ability of plants to defend themselves by accumulating high levels of a toxic element can be overcome by some insects, and that such adaptation potentially echoes in the food web as other predators and parasites may in turn evolve to deal with high levels of the toxic element. view more (2006-11-21)
Is rubber band ligation an effective method to treat symptomatic hemorrhoids?
Haemorrhoids are considered one of the most frequent diseases of the anal region with high prevalence (nearly 50% of proctological visits in a colorectal unit), involving any age and affecting both sexes. view more (2008-12-01)
Unlocking genome of world's worst insect pest
Scientists from CSIRO and the University of Melbourne in Australia, and the Baylor College of Medicine in Houston, Texas, are on the brink of a discovery which will facilitate the development of new, safe, more sustainable ways of controlling the world's worst agricultural insect pest - the moth, Helicoverpa armigera. view more (2008-06-18)
Parasites trigger healthy eating in caterpillars
Some parasites trigger their own destruction by altering their hosts' behavior, researchers at The University of Arizona and Wesleyan University report in Nature. view more (2005-07-29)
Insurgental Biological Warfare Against Gipsy Moth
Specialists of the Institute of Taxonomy and Ecology of Animals (Siberian Branch, Russian Academy of Sciences) investigate peculiarities of struggle against Asian populations of Gipsy moth - one of the most widespread and economically significant forest pests. The methods applied in the North America and Europe do not work with Asian populations... view more... (2005-04-29)
How moths key into the scent of a flower
Moths need just the essence of a flower's scent to identify it, according to new research from The University of Arizona in Tucson. view more (2009-03-05)
Insect pest of potatoes Tecia solanivora is devastating crops in Latin America and has reached the Canary Islands
Lepidopteran Tecia solanivora, an insect pest, is currently devastating potato crops in Latin and Central America. Equador is particularly badly hit. Known as the "Guatemala moth", it spreads quickly. Indeed in 2000 the moth was found to have reached the Canary Islands. Since then it has been on the red list of the European and... view more...

Straighten up and fly right: Moths benefit more from flexible wings than rigid
Most scientists who create models trying to understand the mechanics and aerodynamics of insect flight have assumed that insect wings are relatively rigid as they flap. view more (2009-06-30)
Can moths or butterflies remember what they learned as caterpillars?
Butterflies and moths are well known for their striking metamorphosis from crawling caterpillars to winged adults. In light of this radical change, not just in body form, but also in lifestyle, diet and dependence on particular sensory cues, it would seem unlikely that learned associations or memories formed at the larval or caterpillar stage... view more...

WFU study finds that moths mimic sounds to survive
In a night sky filled with hungry bats, good-tasting moths increase their chances of survival by mimicking the sounds of their bad-tasting cousins, according to a new Wake Forest University study. view more (2007-05-31)
The Guatemalan moth Tecia solanivora devastating potato crops in Equador
Colorado beetles, cyst nematodes, noctuid moths and green-spotted aphids all have something in common. They are pests that attack potato crops. They are by no means the only ones. The moth Tecia solanivora from Guatemala could be added to the list. At present, this ravaging insect is one of the major concerns of farmers in Equador where a harvest... view more... (2000-11-07)
Could Bt transgenic crops have nutritionally favourable effects on insects?
Researchers from Imperial College, England have just shown in a forthcoming article in the journal Ecology Letters, that insect larvae can use an engineered toxin (Cry1Ac) as a supplementary food source. They found that toxin-resistant larvae of the Diamondback Moth developed faster and had a greater pupal weight in the presence of the toxin.... view more... (2003-03-12)
Accessory protein determines whether pheromones are detected
Pheromones are like the molecules you taste as you chomp on a greasy french fry: big and fatty. view more (2007-10-18)
Obesity Crisis in Insects? Not a Problem, Says Expert
Ever seen a fat insect? Probably not. Dr. Spencer Behmer may have the answer why, and that could have implications for what is billed as the current human obesity epidemic. view more (2006-09-22)
