Wasps Control in Hyderabad
The nests are preferably made in the ground, in caves abandoned by rodents, along canals, between tree roots, but can also form aerial nests between tree branches, roofs, facades of buildings and abandoned apiaries. In the nest is the queen, eggs that will give origin to workers, the larvae of workers and the adult workers who are in charge of feeding the progeny. It is the queen who during winter fertilize winter, which is in charge of the beginning of spring to build the nest, digging and forming the first blade of the honeycomb that covers it with vegetable fiber from the bark of the trees. The queen places the eggs, from where the larvae originate; These first larvae are fed by the queen until they become workers, After the first workers emerge, which takes about a month. The queen then laid only eggs and the workers worked to build the nest during the rest of spring and summer, producing up to 14 combs joined by a kind of lace and covered with vegetable fiber with 8,000 workers. The workers are responsible for feeding the progeny using protein and sugary foods, which is why they feed mainly on fruits (peaches, pears, figs, grapes) and dried fruits. They can also eat outdoor meat, charqui and dog and cat food. In the last season, has also been determined in the Metropolitan Region and Region VI, The damage that the workers do in bee hives producing in many cases the death of the hive. It is at the end of summer that adult males appear that are fed by the workers so that at this time they become more harmful by increasing their search for sugary food to satisfy their own demand, that of larvae and that of males. In autumn, the cells of new queens are built. When they ripen, which happens late in the fall, copulation takes place and so the fertilized queens spend the winter hibernating in dry and protected places, whether under the bark of trees, in cracks, among sacks, etc. In Chile in the central zone, nests have been found with up to 277 queens. When winter arrives with the low temperatures the old hive dies, Wasps Control At present there are three methods to control their population in the countries where this pest occurs:
- A) Biological control, through the use of parasitoids and pathogens.
- B) Control of nests by applying insecticides or manually destroying nests.
- C) Chemical control through the use of toxic baits.
- D) Control of nests either manually or with insecticide application directly on the nest should be done first by placing the nests, either on the ground or on the ceilings. It has the disadvantage that if done when the nest has the maximum development, it is not possible to control the new queens.
- For good control of wasps should take into consideration the following: The control, should be started in late fall before the new queens fly outside the nest.
- For this it is necessary to arrive with the insecticide that is decided to apply deep in the nest, because from the third floor down, the queens are located. Be sure to apply seven days of application that is actually controlled.
- Control with pesticides, queens flying in spring, close to marked sectors Control with homemade traps, based on soapy water and meat or use of traps with protein baits and attraction pheromones, these two types of traps allow to catch queens and the first workers who fly in the month of November. Control with toxic baits of the nests that are maintained in spring - summer, using insecticides in sublethal doses, that allow total control of the nest, killing larvae, queens and workers.
