科學圖說 Scientific introduction

近年來有機農業日漸盛行，生物防治法就是採取非農藥自然防治法的一環，即利用害蟲的天敵來達到防治的目的。施放平腹小蜂被視為防治荔枝椿象的終極武器，其體長約3~4毫米，屬於寄生性天敵昆蟲。藉由平腹小蜂會寄生卵的特性，來抑制荔枝椿象的繁殖。圖為平腹小蜂正準備在黃斑椿象卵中產卵。

Organic farming has become increasingly popular in the past decades. Farmers use eco-friendly methods including biological control instead of chemicals to control pests. A common way is to raise and release natural predators to reduce pests in the field. Parasitoid wasp Anastatus japonicus is an ultimate weapon against lychee stink bug Tessaratoma papillosa. This tiny wasp is about 3-4mm long. They are parasitic on the eggs which can help control the pest population.The picture shows the wasp is preparing to lay eggs in the egg of yellow spotted stink bug Erthesina fullo.
