Opornosc stawonogow hematofagicznych - narastajacy problem. 1.Mechanizmy opornosci na insektycydy

Resistance in the hematophagous arthropods - problem on the rise. I. Resistance mechanisms to insecticides. Hematophagous arthropods are pesky but can also be very dangerous to human health due to their ability to act as vectors to many viral, bacterial or parasite-related diseases. The common application of chemicals to control pests leaded to the increasing resistance to pesticides among both insects and ticks. The causes underlying the appearance of the resistance and the mechanisms involved are presented in this article. The description of mechanisms is presented starting from decreased penetration of the pesticide, to an increase in metabolism of pesticide, to the reduced sensitivity of the pesticide's target.

Zbadano oporność na permetrynę, deltametrynę, cypermetrynę, etofenproks, bendiokarb i propoksur prusaków odłowionych w szpitalach w różnych miejscowościach na terenie Polski.

The resistance to four pyrethroid insecticides: permethrin, deltamethrin, Cypermethrin, etofenprox, and to two carbamate insecticides - bendiocarb, propoxur was investigated on field strains of German cockroaches (Blatella germanica L.) caught in hospitals from various parts of Poland. The tests were carried out only on males by the contact method recommended by the WHO. The resistance was evaluated on the basis of LT50s and resistance ratios (RRs). The tested fields strains showed high or moderate resistance to permethrin, deltamethrin, Cypermethrin and bendiocarb: moderate resistance or tolerance to etofenproks (this compound has been never used in Poland before), and tolerance or susceptibility to propoxur.
