WASP LIFE CYCLE
It is important to understand the life cycle of the wasp in order to successfully get rid of them. For convenience, the wasp life cycle can be divided into four stages.
The first stage of the life cycle is hibernation. During the winter month the wasp colonies die of because of starvation not due to cold temperature due to lack of food. Only sexually mated queens over winter by hibernating. When the temperature climbs up about 10°C Overwintering queen wasps emerge from hibernation .The queen builds a basic wood fibre nest about the size of walnut . she starts laying egg in each chamber.
After awaking from hibernation queen looks for food to feed herself , at the same time she has to find a suitable place to build up the nest.In order to start up her nest she will scrap wood from tress ,decking ,garden furniture and flowers with her powerful jaws. She mixes it with her saliva to form sticky cellulose . First of all she makes the petiole or stalk for the attachment of hexagonal cell .she repeats the same pattern and construct the familiar hexagonal shape. She lays egg in each one hexagonal section and uses the stored sperm of winter to fertilize the eggs. She normaly has enough sperm to fertilize the eggs without the need of repeated mating with a male wasp.
when the sufficient number of wasp hatch our the Colony growth really speeds up.The wasp then take over the duties of queen. The worker wasps undertake a complex series of following tasks.
- Younger worker wasps keep the nest clean by carrying away the garbage( detritus).
- Find water which they deposit on the outside of the nest to keep the nest cool.
- Fan the water to help evaporate it to aid cooling.Find wood for nest building.
- Hunt for insects to feed the grubs in the nest.
- The grubs in return feed the worker wasps with sweet sugary liquid.
- Work in the nursery helping newly hatched adults to emerge.
- Guard the nest.
- spread the orders of the queen to each other and tend to her needs.
AT the end of Summer season the queens is not having enough sperm to fertilize all the eggs. So she decides what eggs she will go fertilize and which one she will leave unfertilize .The size of the wasp hive has expanded considerably.The fertilize eggs will be the future queens or worker and the unfertilized eggs will turn in to drones or male wasps.Once the new queens have mated, they fly off to find shelter in a bid to survive until the next spring. The mated queens do not return to their old nest.
