Diamondback moths which were confined individually in petri dishes, laid few eggs on cabbage leaves, whereas they successfully laid eggs on the upper or lower surface of the leaves sprayed with spreader. In the choice experiment using polyester-gauze cages (40×40×40cm) containing the leaves sprayed with the spreader and untreated ones, diamondback moths laid much more eggs on the former than on the latter. These results indicate that the spreader weakens the function of the leaf surface wax bloom which suppresses oviposition of diamondback moths.
