Resistance of the German cockroach Blattella germanica (L.) to dioxacarb in Bulgaria.
The level of susceptibility of 15 wild populations Blattella germanica (L.) from 9 various regions in Bulgaria to dioxacarb was studied. The compound was applied by jar impregnation. The method recommended by WHO was used. LT50s and LT90s were calculated. These values were compared with those observed for the laboratory strain. A total of 4,080 males, females and nymphs were tested. Low to high resistance with Ri = 1.54X ... 25.38X at LT50 was established.
