The blueberry gall midge, Dasineura oxycoccana Johnson, is a serious pest of rabbiteye blueberries in Florida, Georgia, and Mississippi, and a potential pest of southern and northern highbush blueberries. Its damage has been observed with increasing frequency in highbush blueberry plantings in the Great Lakes region, including in Wisconsin and in Michigan. Unlike in rabbiteye blueberry plantin...

Myiasis is a condition in which fly maggots feed off, and develop in, the tissues of living organisms. True myiasis results from files deliberately laying eggs in or on the tissues. There are two forms of myiasis: obligate, in which it is necessary for the maggots to feed on living tissues, and facultative, where files opportunistically take advantage of wounds or degenerative necrotic conditio...

A patient is reported who, after leaving Venezuela, developed some boils on the left upper limb inhabited by Dermatobia hominis larvae. The curious life-cycle of this tropical fly is described with some considerations about the diagnostic problem. A simple unreported way of larvae extraction is suggested.

the objective was to study the population development of tuta absoluta (meyrick, 1917) on tomato in greenhouse conditions at droh. the trial assessed the occurrence of t. absoluta adults from the month of october to may in traps; a low numbers is noted. the high numbers recorded (170 adults/greenhouse) are caught at the end of crop cycle. the mean number of capture is 22 adults/ week/ trap. reg...

The response of broad bean (Vicia faba) plants to water stress alone and in combination with green stink bug (Nezara viridula) infestation was investigated through measurement of: (1) leaf gas exchange; (2) plant hormone titres of abscisic acid (ABA) and its metabolites, and of salicylic acid (SA); and (3) hydrogen peroxide (H2O2) content. Furthermore, we evaluated the effects of experimentally...

Over the past fifty years, annual honeybee (Apis mellifera) colony losses have been steadily increasing worldwide. These losses have occurred in parallel with the global spread of the honeybee parasite Varroa destructor. Indeed, Varroa mite infestations are considered to be a key explanatory factor for the widespread increase in annual honeybee colony mortality. The host-parasite relationship b...
