Özet

The poultry red mite, Dermanyssus gallinae (Arachnida: Dermanyssidae) is a pest that causes significant economic

loss in laying hens for which control methods are limited. In this study, the effects of 20 indigenous fungal strains

on poultry red mites in chicken farms were investigated. All experiments were conducted under laboratory

condition at 28 ± 1 ◦C and 80 ± 5% humidity. A screening test showed that Metharizium flavoviride strain As-2

and Beauveria bassiana strain Pa4 had the greatest measured effect on D. gallinae at 1 × 107 conidia/ml 7 days

after application. In a subsequent does-response experiment, these strains also caused 92.7% mortality at 1 × 109

conidia/ml within the same period. The LC50 of these strains was 5.5 × 104 (95% CI: 0.8–37.5) conidia/ml for As-

2 and 3.2 × 104 (95% CI: 0.4–26.0) conidia/ml for Pa4, and their LT50 were 1.94 and 1.57 days, respectively. The

commercial Metarhizium anisopliae bioinsecticide Bio-Storm 1.15% WP, used as a comparator, had LC50 and LT50

1 × 105 (95% CI: 0.1–7.9) conidia/ml and 3.03 (95% CI: 2.4–3.8) days, respectively. It is suggested that

mycoacaricides could be developed using the best two fungal strains found in this study (As-2 and Pa4),

providing potential for biological control of poultry red mites.
