Abstract


The fruit fly Bactrocera spp. is an important pest of fruits, especially mango. The adult female lays eggs in maturing fruits. The maggots develop in the fruit and cause fruit drop and rotting. The best way to prevent fruit fly  infestation is to follow an integrated approach of traps (at least 30 days prior to harvest) + sanitation (removal and destruction of all fallen fruits, 40 days prior to harvest) and soil raking below the tree (once or twice starting a month prior to harvest, if possible). The trap consists of methyl eugenol (ME), a para-pheromone (mixed with a toxicant), which attracts only the males of certain species ·of Bactrocera, and therefore is called male annihilation technique (MAT). In the absence of males, females fail to
procreate, and hence fruits will be free of infestation.
