Insects have an important role in human life, When hearing the name of insects, it is always identified with pests in agriculture that are harmful, such as puppeteer, planthopper, grayak caterpillar and lain.Serangga can damage the plant as a pest and the source of vector disease diamanusia.Namun, not all insects are as pests or vectors of disease. The insects are also needed for human life. The bees' bee, grasshopper, crickets, silkworms, beetles, ants help humans in the process of pollination of plants and produce health food products. The insect vulnerabilities in ecosystems are among others pollinators, decomposers, predators (biological controllers), parasitoids to as bioindicators for aekosistem so that the use of insects that will be very influential in agriculture.
Insects as pollinators for example are bees and butterflies. Bees are also the only insects in charge of accelerating the pollination of flowers. But he is the only insect that when pollination does not cause adverse side effects for plants. In contrast to butterflies, for example, there is a deny that kupukupu that sucking honey itumampu help attach the pollen to the pistil of a flower, and it will facilitate the process of forming fruit.But the butterflies demanded repayment jasayang sometimes too expensive.Hundreds of eggs attached to the leaves, will hatch into a greedy caterpillar chewing plant leaves. Plants are not a profit but a loss.
Bees themselves are important plant pollinators in nature compared to wind, water and other insects. Many researchers have suggested that there is an increase in production if a number of bee colonies are located around the locality. The bees have special organs to take nectar, called proboscis that looks like a trunk on an elephant. Proboscis has the ability to suck nectar fluid on the flowers. The effectiveness of the bees fly collects nectar and polyds from early morning to late afternoon. Poles are required by maduterutama bees as a source of protein and fat, and little carbohydrates and minerals. The bee's activity is done accidentally during a nectar search and pollen as a feed ingredient for the colonies.In addition as pollinators, insects are also decomposers or decomposers.The insects will eat the plants h old so as to restore the nutrients in the soil and make the soil fertile.
