Plant Lice Natural Remedies

There are natural remedies for plant lice, luckily for gardeners. One of the remedies consists in trying to strengthen the presence of ladybugs in the garden, trying to limit the use of pesticides which, with their poor selectivity, free the plants from aggressors, but also exterminate useful insects, including ladybugs. Yes, because ladybugs, scientific name Adalia bipunctata, are one of the greatest enemies of aphids, an adult specimen can eat up to a hundred aphids a day and when it is in the larval state even 150! Not bad, as a start. The larvae of hoverflies and chrysopids (or chrysopes) are also relentless enemies of aphids. The Chrysoperla carnea, a small wasp, lays its eggs inside the aphid larvae and adults, which they will feed on.


Plant lice how to get rid of them

If you have problems with plant lice, how to eliminate them is not a problem: there is no shortage of remedies: in addition to ladybugs, hoverflies, chrysopids and Chrysoperla carnea, birds can also give a valid help against lice: tits, for example, they are large predators of aphids. Plants also enter the battlefield, first of all macerated with nettle (among other things, it also serves against mites and molds). Following chilli macerate, another effective remedy. The infusion of mint is a remedy that we could define by reflex: it is not effective against aphids, but against the ants that practically raise aphids, because they are greedy for the honey that these little animals secrete; counteracting them helps keep the plant lice population under control as well.


Plant lice - 1

Plant lice are several thousand species, divided into three families, belonging to the Rhynchota Order. They are very small: between 1 and 3 millimeters long and stocky, with short legs, the ovoid shape, a little more tapered in the front. There are both species with wings and without them, those that have them are able to cover even distances of the order of tens of kilometers. On their head are three simple eyes. With their mouthparts which are of the stinging-sucking type, they pierce the leaves, the young parts of the branches, the new shoots and the semi-woody trunks to suck the sap. With this action they cause leaf deformations, weaken the plant and often transmit virosis to plants.

They have thin, elongated antennae pointing upwards and bent backwards which in some cases measure as much as the whole animal. Aphids are present in many colors, there are yellow, brown, red, black and even green. Generally they die in winter and only the eggs survive until the following spring, but if the winter is not cold the adults can survive too. Their "highlight", in which the greatest presence occurs, is spring, followed by summer; because in spring the eggs laid in autumn hatch, in addition to those that the females lay in the spring and which develop by parthenogenesis (the ability of the egg to evolve even without having been fertilized). Winged shapes that also manifest themselves in summer, therefore very mobile, complete the rest.
