Abstract

The infectivity of Beauveria bassiana (Balsamo) Vuillemin isolates from Hypera postica (Gyllenhal) (Coleoptera, Curculionidae) and Gonioctena fornicata (Brüggemann) (Coleoptera, Chrysomelidae) collected from alfalfa fields in Tokat Province, Turkey for G. fornicata larvae were evaluated under laboratory conditions. Ten B. bassiana isolates were used in single screening test to determine their efficacy against G. fornicata larvae at a concentration of 1 x 107 conidia/ml. In addition, dose-mortality tests were carried out with the isolates GN-8-2, GN-4, GN-8-1(2) and GN-12-3. They caused more than 90% mortality at 7 days post-treatment at doses of 1x105, 1x108 and 1x109 conidia/ml. In the dose-mortality tests, almost all isolates caused 100% mortality at 1x109 conidia/ml at 7 days. The LT50 and LT90 rates at 1×108 conidia/ml were also determined. In summary, the Gonioctena fornicata larvae were susceptible to all the B. bassiana isolates used in the dose-mortality studies.

Özet

Tokat ili yonca alanlarından toplanan Hypera postica (Gyllenhal) (Coleoptera: Curculionidae) ve Gonioctena fornicata (Brüggemann) (Coleoptera, Chrysomelidae) erginlerinden elde edilen Beauveria bassiana (Balsamo) Vuillemin izolatlarının G. fornicata’nın larvasına karşı laboratuvar şartlarında etkinliği araştırılmıştır. On B. bassiana izolatı tek dozda (1x107 konidia/ml) G. fornicata larvalarına karşı test edilmiştir. 7.günde %90’nın üzerinde etkiye sahip olduğu belirtlenen 4 izolat ile [GN-8-2, GN-4, GN-8-1(2) GN-12-3] 1x105, 1x108 ve 1x109 konidia/ml dozları kulanarak doz ölüm çalışmaları yürütülmüştür. Doz ölüm çalışmalarında, 1×109 konidi/ml dozunda 7. günde hemen hemen tüm izolatlar %100 etki göştermiştir. 1×108 konidi/ml dozunda LT50 ve LT90 değerleri belirlenmiştir. Elde edilen sonuçlara göre G. fornicata larvalarının doz-ölüm çalışmalarında kullanılan tüm B. bassiana izolatlarına karşı hassas olduğu belirlenmiştir.
