Abstract
Susceptibility of the egg stage of potato tuber mothPhthorimaeaoperculella to native isolates of Beauveriabassiana
Highlights
Potato tuber moth (Gelechiidae: Lepidoptera) Phthorimaea operculella is one of worldwide spread pests on potato and Solanaceae [1, 2]
Isolate B realized that has more germination ratio (67%) with significant difference from the isolate C which reached 48%, while isolate D reached to 55%
The pathogenicity of three local isolates of the entomopathogenic fungus Beauveria bassiana (Bals.) Vuill was evaluated on eggs of potato tuber moth P. operculella (Zeller)
Summary
Potato tuber moth (Gelechiidae: Lepidoptera) Phthorimaea operculella is one of worldwide spread pests on potato and Solanaceae [1, 2]. The female lay her eggs on the leaves and noncovered tubers near to eyes (buds), larvae dig tunnels during their nutrition causes damages that reach approximately 100% on cultivated and stored potato [3, 4]. Biological origin insecticides like entomopathogenic viruses from group baculovirus [11] are used, as well as entomopathogenic fungi like Beauveria bassiana (Hypocreales: clavicipitaceae) [12, 13]
