Effect of some plant chemical compounds on the behaviour and reproduction of spider mites (acarina: tetranychidae)
1978
DABROWSKI, Z.T. | BIELAK, B.
A comparison is made between testing techniques for examination of spider mites on their host plants. The female fecundity is related to chemical composition of different rose and strawberry cultivars using Tetranychus urticae and Panonychus ulmi. From stepwise regression analysis it is shown that a number of amino acids and minerals are correlated with mite fecundity, but the effects vary with the host plant species and cultivar. Mineral nutrition of the plant increases fecundity, while certain phenolic compounds apparently decrease it. An attempt was made to correlate female fecundity with the amounts of feeding, using plants which were radio-labelled.
