The Logroño City Council has announced a biological control plan for its parks and gardens. This spring, it will release ladybugs and predatory bugs (Anthocoris nemoralis) in Paseo del Espolón and Parque Gallarza. The goal is to reduce the use of chemical pesticides, which harm pollinators, contaminate soil and water, and generate resistance in pests.
Insects as bio-tools for more precise control 🐞
The strategy is based on natural predation. Ladybugs feed on aphids, while Anthocoris nemoralis attacks psyllids and mites. By introducing these natural enemies into the urban ecosystem, pest populations are regulated without resorting to synthetic phytosanitary products. This method aims to maintain the biological balance of trees and green areas, avoiding chemical contamination and protecting auxiliary species such as bees.
Goodbye to poison, hello to hungry bugs 🐛
Residents of Logroño will have to get used to seeing more bugs in the parks. But beware, these are not coming to bite, but to gobble up other bugs. If they see a ladybug strolling on a rose bush, don't squash it: it's working. The measure may not please those who hate insects, but it is better than drenching plants in chemicals. After all, it's the garden version of Star Wars: the good guys versus the bad guys.
