<p>There are described traps for the capture of insects, of the type comprising a capturing chamber with a funnel-shaped closure, the efficiency of which is increased by a polytetrafluoroethylene coating of the inner walls of the funnel. Said traps, which may be baited either by pherohormone dispensers or by a phagoattracting agent, may be used both for the assessment of the insect population density in a determined area, and for the capture of insects in bulk.</p> |
