Toxicity of potato extract on Tetranychus urticae (Acari : Tetranychidae)‎ and its effect on biology and life table parameters

Abstract EN

The present study aimed to evaluate the unless and harmful part of the potato plant, which is the green part of tubers contains solanine, as a botanical pesticide.

The red spider mite Tetranychus urticae Koch (Acari: Tetranychidae) is one of the most dangerous pests all over the world.

It has been reported to attack about 1200 species of plants.

It causes damage to vegetables, sweet corn, beans, peas, hops, grapes, deciduous fruit trees, strawberries and many other fruit, flowers and ornamental plants.

Due to the problems of chemical acaricides to all organisms and environment, natural control replaced pesticides.

The green potato extract contains solanine which is toxic and effective material in control.

Different little concentrations of green potato extract were applied in control of red spider mite and caused high mortality proportion.

In this study, the used concentrations were 1000, 3000, 5000 and 10000 ppm and the mortality increased when the concentrations increased.

LC50 of the extract was 3503.69 ppm and LC90 was 62667.81.

Then, LC50 was applied on adult female for recording its effect on biology and life table.
