Potato tuber moth (PTM), Phthorimaea operculella, is a serious pest of stored potato in most countries where potatoes are grown. Entomopathogens offer promise as alternatives to broad spectrum insecticides for management of this pest. The fungus Muscodor albus, which produces a mixture of antimicrobial volatile organic chemicals, was tested for its insecticidal activity against PTM. Adults and ...

Two new species of Didicrum from Argentina are described and illustrated: Didicrum naimae and Didicrum letitiae, based on male and female specimens. Specimens were collected with Malaise traps located in Nahuel Huapi National Park, Patagonian region. Including the two new species of Didicrum, twelve are described from South America. 

Widespread and prolonged defoliation by the European winter moth, Operophtera brumata L., has occurred in forests of eastern Massachusetts for more than a decade and populations of winter moth continue to invade new areas of New England. This study characterized the forests of eastern Massachusetts invaded by winter moth and related the duration of winter moth defoliation estimated using dendro...

With moth declines reported across Europe, and parallel changes in the amount and spectra of street lighting, it is important to understand exactly how artificial lights affect moth populations. We therefore compared the relative attractiveness of shorter wavelength (SW) and longer wavelength (LW) lighting to macromoths. SW light attracted significantly more individuals and species of moth, eit...

Winter moth, Operophtera brumata L. (Lepidoptera: Geometridae), has been defoliating hardwood trees in eastern Massachusetts since the 1990s. Native to Europe, winter moth has also been detected in Rhode Island, Connecticut, eastern Long Island (NY), New Hampshire, and Maine. Individual tree impacts of winter moth defoliation in New England are currently unknown. Using dendroecological techniqu...

Codling moth (Cydia pomonella L.) is an internal feeding pest of apples and can cause substantial economic losses to fruit growers due to larval feeding which in turn degrades fruit quality and can result in complete crop loss if left uncontrolled. Although this pest originally developed in central Asia, it was not known to occur in China until 1953. For the first three decades the spread of co...

A life-history in which an organism depends on ants is called myrmecophily. Among Lepidoptera (moths and butterflies), many species of lycaenid butterflies are known to show myrmecophily at the larval stage. Descriptions of myrmecophily among moth species, however, are very few and fragmentary. Here, we report the ant-associated behaviour of the tiny Japanese arctiid moth, Nudina artaxidia. Fie...

A preliminary conclusion of the research is that there does not appear to be significant genetic differences in developmental times between the codling moth populations in walnuts and apples. Codling moths were collected from walnuts and placed onto artificial diet as a rearing medium. Data obtained from these individuals were consistent with the data obtained from colonies of codling moth coll...
