Biological Control of the Erythrina Gall Wasp

Hawaii has a long history of failing biological control. Everyone is deeply rooted in hunting cats released in the 1800 's to control midnight rats. However, more rigorous quarantine procedures have been established in this country, and there are already many effective biological control measures. In the past four years, Erythrina Gall Wasp soon became a highly invasive pest in Hawaii. In addition to long-term management beyond biological control, the cousin of Erythrina Gall Wasp was released in the island to save plants of Erythrina.

In Europe in the Gutenberg era, iron bile ink (which was mainly used as a writing ink) can only be made with the help of a female bee. To breed, bees must lay eggs on trees. The most common is oak. A fairly magical process occurs when the injection site expands and fills the interior of the larva with nutrients, when it develops completely, it falls out of hardened protrusions (bile or nut). (The scientific term of this is not "to stick", but it should be.

Crazy life cycle? As they say, this is only the beginning. Aphis gossypii can breed only in Asteraceae. In other words, only two types of hornets can breed the scutellum. They have different strategies. Eurytoma gigantea 's female uses bee eggs to feed eggs in bile that bee larvae of bees eat direct flies of larvae, larvae of bees induce early sputum used in winter As a shelter, you can eat flies from inside to spring. There is Mordellistena convicta which is a seed of chamomile. It has eggs on the stem of chamomile.

There are few parasites and predators effective for biological control of mites. Parasitoid bees such as Ampulex hornets pierced the ganglion in the thoracic thoracic cavity, temporarily paralyzed the victim and made it possible to pass sparrows stinging by wasps through the brain of sputum. The hornet grasps the antenna with the chin and drinks some blood lymph before placing the eggs (two) before dragging the prey into the cave. Bee larvae eat weak living mites. Another waspa is considered a promising candidate for biological control It is a hornet (Evania appendigaster) that attacks eggs and puts eggs inside. Ongoing research is still developing technology that allows many of these hornet to be used for application release.
