The role of ladybugs in plants
Ladybugs are also known as one of the most environmentally friendly pest repellents, in the 19th century, fruit plantations in Asia and the United States were attacked by insect pests known as cotton pillow scales or Icerya purchasi, and had caused great losses, the Hama was actually a kind aphids that live by sucking the plant juice and form a kind of scaly layer around it to protect itself. The animal was carried accidentally from Australia to reach the plantation area on another continent.
The experts then look for ways to eradicate the pest. They finally found that in their natural habitat in Australia, the cotton pillow scales had a natural predator of the vedalia cardinalis, the Ladybug was then taken to a fruit plantation that was attacked by a cotton pillow pest in the 1888s, and within two years it had succeeded in suppressing the population insect pests. This ladybird is then one of the successful examples of pest control by utilizing its behavior in the food chain or bionsektisida.
