外来害虫每年可造成 1.4 万亿美元的经济损失并威胁粮食安全。生物防治是利用天敌来调节动植物数量的自然现象。使用无人机（UAV）作为生物防治的支持平台是有前景的，因为它可以降低运营成本并减少河流和有毒动物等自然屏障的转移。然而，带有天敌的胶囊是由遥控无人机和自主无人机以锯齿形方式传播，覆盖效率低，无法覆盖任何形状的区域。本文提出了一种计算任何形状区域的胶囊沉积位点的算法。在最复杂的情况下，该算法的有效覆盖面积增加了1.54%，覆盖效率提高了9.54%，低效率降低了104.88%，保证了7.16%的边缘区域保护，并需要13.56%的释放胶囊。因此，无人机可用于在任何形状的区域有效地分配用于生物控制的胶囊。它们的主要影响是通过释放更少的胶囊和更好地覆盖农田边界来节省潜在的成本。
Exotic pests can cause US$1.4 trillion financial damage per year and threaten food security. Biological control is a natural phenomenon that regulates the number of plants and animals by means of natural enemies. The use of unmanned aerial vehicles (UAV) as a support platform for biological control is promising, since it can reduce operating costs and transposition of natural barriers, such as rivers and venomous animals. However, capsules with natural enemies are spread by a remotely piloted UAV and autonomous UAVs in a zigzag pattern, which incur low coverage efficiency and cannot cover areas of any shape. This article proposes an algorithm that calculates capsule deposition sites of areas of any shape. In the most complex situation, the algorithm showed 1.54% more of effectively covered area, 9.54% higher coverage efficiency, and 104.88% lower inefficiency, guaranteed 7.16% protection of the edge region, and required 13.56% of released capsules. Therefore, UAVs can be used for an efficient distribution of capsules for biological control in areas of any shape. Their main impacts are potential cost savings by the release of fewer capsules and better coverage of the border of the crop field.
