Ecological environment protection: the natural factor of agriculture, strengthen the ecological environment protection with the natural enemies of insect pests

Human beings need food and society needs agriculture, so what can we do to better develop agriculture? is agriculture bound to destroy the ecology? In order to reduce the use of pesticides and protect the ecology, the upcoming special exhibition "sharing Nature" to be held by the Zhi Nong Museum of Huabo Waipu Park in Taichung will showcase the agricultural technology of Taiwan's "friendly agriculture" and see what we can do to reduce the burden and damage to the environment. Towards a sustainable vision.

Predatory Chrysopus, the natural enemy of pests and aphids, can naturally achieve ecological balance through the food chain. Army of natural enemies of mantis, lacewings and parasitoids to control insects. "if our natural enemies in nature are not killed, such as the wide-eating mantis and the lacewings that deal with small pests, we can achieve the effect of controlling insects with insects. Lu Meijun, director of the biological control branch of the Miaoli Agricultural Reform Farm, said that this "shared nature" exhibition advocates the practice of "taking nature and giving back nature."

In nature, it has its own law of balance, including vegetable-loving pests and meat-loving beneficial insects. Predatory beneficial insects, such as lacewings, mantis, and parasitic wasps, are the natural enemies of pests, and they naturally achieve ecological balance through the food chain. For example, aphids, such as those commonly found in farms where single crops are heavily planted, cruciferous cabbage and pakchoi, rely mostly on spraying pesticides for prevention and control. On the other hand, in a natural environment with a wide variety of crops, or farmers engaged in organic or friendly farming methods, they can achieve the effect of "controlling insects with insects" by raising their natural enemies, "lacewings."

The creation of a wild flower blanket can increase the number of beneficial insects, the more diverse the biological species, and the more stable the ecosystem. Once upon a time, native wild flowers could be seen in Taiwan's rural areas, be they ridges, vegetable gardens, and wild fields. around the 1960s, herbicides began to prevail, and the ridges gradually cemented, and many native wildflowers gradually disappeared. In this exhibition, an area of wild flower blankets has been created to let the public understand its importance. For example, planting Compositae plants on the ridges can increase the number of beneficial insects and control common planthopper and borer pests in rice fields because of the "large number of flowers and long flowering period" of Compositae. The more diverse the biological species, the more stable the ecosystem will be.

Pheromone attractant can be used on sweet potato ant elephant that can eat sweet potato. Synthetic sex pheromone can trap a large number of adults of male ant elephant. Like humans, there are pheromones in the insect community. Insects release pheromones to attract mates. As long as you understand the habits of insects and make pheromone attractants, you can help farmers strike a balance between ecology and crop harvest. For example, like the sweet potato ant elephant, it is a kind of murderer who makes sweet potato eaten in a mess and causes sweet potato smell. A large number of male ant elephants can be trapped by synthetic sex pheromone. So that the female ant elephant can not find a partner, insect pests can be reduced and the harvest of farmers can be saved. "it's not just love. In addition to seducing, pheromone has a warning effect! "the director of Lu Fen said with a smile. For example, with the release of "Alert pheromone," Palutian can make Palenong's most nerve-racking thrips feel uncomfortable and fly away as soon as they fly into the field.

There are also many environment-friendly agricultural technologies, such as bee pollination, forest economy, and so on, which will be presented at the "sharing Nature" special exhibition at the Zhi Nong Museum in Huabo Waipu Park, Taichung. Let's work together for a sustainable future.
