To be efficient, food baits must attract pests so that contact is made with the active substance and/or that it is ingested. Food baits may be less efficient for ...

Many synanthropic species of insects occur in households and other domestic situations. Some of these pests are very well known to inhabitants, e.g. ants, silverfish or cockroaches. While small insects, such as psocids, are often overlooked. Synanthropic species of psocids (especially from the gener...

Insecticide resistance problems have been recognised as an increasing problem in Europe as a consequence of both the accumulation of resistance mechanisms by some species and the greater diversity of arthropods becoming a pest problem. Arthropods of particular concern include public health and lives...

Two Navy surplus barges (each 91 x 20 ft) were equipped with one street lamp at each corner of the barge and with fourteen 60 x 80 inches white cloth panels, each panel illuminated with one 100W spotlight.
