Outline of Final Research Achievements

Five phytophagous insect species grew completely when fed on detached Sicyos angulatus leaves, while they did not grow when fed on S. angulatus leaves on intact plants. Cucurbitaceae specialist beetle species make a trench when fed on their host plant leaves. Cucumber beetle species fed on the leaves on intact plants after making a trench. While cucurbit-feeding phytophagous lady beetle species scarcely fed on the leaves on intact plants in spite of making a trench. These results indicate that the ability of making an effective trench make phytophagous insects feeding on S. angulatus leaves on the intact plants.
