The soursop should be being attacked by mealybugs, sucking insect that produces a sweet substance that attracts ants. After hatching from eggs deposited by colchonilhas in fruits, succeeds larval stage or nymph. Despite the protection, it is possible that there was already the presence of eggs or nymphs in some fruits when they were bagged. To prevent this from happening again, before bagging use a toothbrush to clean the entire surface of the fruit and eliminate foci of plague. The control cochineal can be made by applying mineral oil or vegetable product that causes the death by suffocation of the insects on them to form a film that prevents breathing. It is recommended to use a volume of 10 milliliters of oil per liter of water. It can also be adopted a combination of syrup smoke. Mix 100 grams tobacco string with half a liter of alcohol and then add half a pint of water. Keep the solution at rest for 15 days. Cut 100 grams of neutral soap stone into small pieces and dissolve them in 10 liters of hot water. Let cool and add to the mixture tanned and strained. Sprays should be applied at the end of the day.
