The growth rate of poinsettia thrips (echinothrips americanus) varies from 15.0 to 32.5 ± 1°C at 2.5°C. Table 1 shows yellow flower thrips using kidney beans. Southeast Asia ⦁ First discovered in Korea on Jeju Island in 1993 ⦁ Asymmetrical stripe.

It usually takes 10 to 20 days from egg to adult, and the higher the temperature, the faster it becomes, causing the population to increase rapidly. Although thrips are insects that undergo incomplete metamorphosis, they are similar to endophytes that undergo complete metamorphosis. It mainly occurs in facility cultivation areas, and although its occurrence decreases in the summer due to high temperatures, it increases again in the fall and winters in facilities in the winter.
Nymphs are called larvae because they are wingless like endothelials until the second instar.
⦁ Occurs year-round on flowering crops in facility greenhouses ⦁ Yellow flower thrips, Taiwanese thrips, cucumber thrips, etc. ⦁ Place of origin: It is no exaggeration to say that timing is everything when it comes to controlling thrips. Interval (65±5% rh, 16l: Additionally, overcrowding and incorrect management of crops are also causes of thrips.
The high temperature and low humidity inside the greenhouse promote the growth of thrips. Thrips are small in size and live in flowers or leaves. The most basic data needed to predict the peak period and amount of pest population development are zero point temperature, effective cumulative temperature, and reproductive table statistics.
