Fruit flies are a type of insect that is a pest of various types of fruit such as mango, guava, star fruit, and others. This type of insect is a pest that is difficult to control with insecticides. Because the fruit fly caterpillars eat the inside of the fruit not the outside of the fruit, the use of insecticides is ineffective because they are unable to reach the inside of the fruit. The existence of fruit caterpillars is a scourge for fruit farmers, so that many farmers experience considerable losses. And I took the picture using my cellphone camera.
