Parasites are closely related to other creatures and their hosts and do damage. The parasite depends on the host's life function. For example, a virus is a common parasite. The parasites must survive, grow and breed within their host. Parasites rarely kill hosts. A well-known type of parasite is hookworm. Humans and their pets can get them. Hookworms adhere to the inner layer of the small intestine and cause disease and malnutrition as they eat nutrients and prevent them from entering the host.
Regardless of their reputation, Tarantula itself is the target of predation. The most special of these predators is a large member of the genus Pompilidae, such as a hornet, Hemipepsis ustulata. These bees are known as "wolf spiders". The largest tarantula like the genus Pepsis tracks, attacks and kills the large tarantula. They used the sense of smell to find a Tarantula's retreat. The wasp must be stabbed with the film between the base legs, under the chest of the spider's head. This will cause the spider to lick, then the bee draws it back into the cave, then places the egg on the abdomen of the prey. Later the hornet locks the spider in the cave, fly away and finds more hosts. Hornets larvae hatching unwanted parts of spiders and eat, the rest consumes as they approach sputum. Other arthropods such as gigantic crickets are also known as predatory tarantulas.
When the eggs in the egg are ready for placement, the mother's bees kill the tarantula. Afternoon on a sunny day flying low on the ground, the bees looked for the victim, a circular hole made from the edge of a small silk, the mouth of the Tarantula cave. There is no difference in spider sex, but mother has a high opinion about that species. Each Pepsi requires a specific species of tarantula, and the hornets do not attack the wrong species. There are spiders in the cage that are not ordinary prey, but hornets kill at night by avoiding spiders.
Insects such as moths, flies, bees, beetles are important pollinators. Some ants, wasps and flies / beetle larvae play an important role in reducing pests. In addition, insects help to reduce harmful weeds on the farm. The economic value of pollination services provided by insects is estimated to exceed EUR 150 billion (1). There is an attractive mechanism behind the services insects provide to us. For example, certain bees called "parasitoid bees" lay eggs on serious insect pests such as aphids. Eggs hatch on larvae, then larvae eat aphids from the inside and then look like adult bees. In addition, some Ali ingest certain pearl / shiny food compounds from certain plants and protect plants from pests.
