Momordica charantia is therophyte vine plants. It is called natural insulin and contains carantine and vitamin C and so on. Momordica charantia is one of the representative subtropical crops as a functional crop, showing efficacy on improvement of diabetes, cancer, abdominal obesity and improvement of hypertension.
According to climate change, Momordica charantia is growing cultivation area, but there is still insufficient research for insect pest occurrence and insecticides. Due to the lack of proper control measures, the damage caused by insect pests is increasing as the year goes by.
This study was conducted to investigate the occurrence and damage of insect pests in Momordica charantia and utilize it as basic data for development of insect pest control technology. As a result, 5 orders of 13 species of insect pests were investicated. Among them, Aphis gossypii, Frankliniella intonsa, and Frankliniella occidentalis showed high density. In particular, Aphis gossypii showed the highest density in mid-May, also Frankliniella intonsa and Frankliniella occidentalis showed high density in the middle of June. The leaf damage caused by the larvae of Palpita indica was observed in late June. After mid July, the biginning of the high temperature period, the insect pest density decreased, but the damages caused by moths were severe.
