Sustainable management of fruit fly infestation in guava for quality fruit production:A review

Abstract

The guava is a tropical fruit that originated in Central and South America and has  since been grown in many tropical and subtropical areas worldwide. In these regions,  guava fruit fly, Bactrocera correcta, is a noteworthy pest of guava and other fruits.  This particular species of fruit fly lays its eggs in ripening or ripe fruits of guavas,  which may culminate in infestations which significantly damage crops. The female  guava fruit fly normally releases the eggs within the fruit as part of the life cycle.  After hatching, the larvae feed the fruit pulp, which makes it rot and unfit for human  eating. In cases of severe infestation, this not only diminishes the fruit’s yield and  quality but also makes it unmarketable. Controlling the guava fruit fly often involves  a combination of cultural, mechanical, biological, and chemical methods. These  can include techniques such as fruit bagging, sanitation, trapping, para-pheromone  lure, bait spray, biocontrol, bio-pesticide and the application of insecticides. Fruit  fly populations can be effectively managed by using fewer chemical pesticides and  implementing integrated pest management (IPM) techniques. Maintaining the  productivity and quality of guava crops, as well as other susceptible fruits in affected  areas requires efforts to control the guava fruit fly.
