Red mites of the species Tetranychus merganser are little arthropods and close relatives to spiders which spin silk webs for their colonies. In China, the U. But now, a group of scientists has found a potential natural insecticide from a plant native to India and Pakistan: Moringa oleifera. The use of moringa as what causes little white bugs on plants bioinsectide what causes little white bugs on plants not only effective against mites; it also offers a less polluting and safer alternative for human health than chemical insecticides, explain researchers from several Mexican institutions who published their work in the journal Plantas last May.

In bean plants, for example, damage from these mites appears as white spots near the veins of the affected plant. Despite living only about eight days, these small arachnids how to stay cool in the beginning of a relationship fast causing great problems in crops.

If plants are left unattended, they eventually die. Methods to control mite pests include chemical insecticides, but such compounds have an increasingly bad reputation not only because they are highly polluting and leave residues in the place of application, but because they are harmful to people who handle them. What causes little white bugs on plants also lose effectiveness over time when mites become immune to this type of products, as it happens in other species of the genus Tetranychus.

Moringa oleifera is a fast-growing tree living in tropical and subtropical environments which has has been reported to be drought tolerant, making it ideal for growing in areas where water is scarce. Researchers from five universities in northern Mexico found that the extract of moringa leaves causes sterility in female mites, meaning fewer eggs. Researchers collected clean, mature leaves from a two-year-old moringa tree, from which they obtained an ethanolic extract that they later analysed to determine its chemical composition.

They sprayed different concentrations of the extract on female mites feeding of bean leaves placed in Petri dishes. Additionally, the application of the bioinsecticide also decreased the number of hatched eggs by preventing gas exchange of the embryos. Secondary metabolites, like alkaloids, present in the leaves of Moringa oleifera are responsible for this mortality. These chemical compounds also act on the nervous system, affecting behavior and slowing growth.

Another advantage of using moringa as a bioinsecticide is that the trees constantly produce leaves and that collecting them does not put the tree at risk, according to the researchers. Although the road to the commercial use of a moringa-based bioinsecticide is long, the group of researchers is not ruling it out. We do what are the effects of online teaching seek to eliminate pests or insects, [but] rather reduce their populations so that they do not cause economic damage.

It will also be necessary to take the experiment from the lab and into the field to determine its effectiveness in natural conditions, which include interactions with abiotic and biotic factors.
