Biological control is an environmentally sound and effective means of reducing or mitigating pests and pest effects through the use of natural enemies. The aim of Biological Control is to promote this science and technology through publication of original research articles and reviews of research and theory. The journal devotes a section to reports on biotechnologies dealing with . Studies on fungi in Egypt started at the beginning of the 19 th century on lichens (e.g. Delile a, b, Nylander , , Müller a–c, , Stizenberger , ).In the early 20 th century, Sickenberger and Steiner (, ) provided information for collections of lichens from Egypt in the 19 th and early 20 th Century.

The first of these publications on aphids that attack the roots of plants in Egypt [cf. R.A.E., A 53] deals with the morphology and taxonomy of 16 species.
It includes a list of the aphids concerned, showing their food-plants, distribution and seasonal occurrence, and another in which they appear under their food-plants.

Parasitism is a kind of symbiosis, a close and persistent long-term biological interaction between a parasite and its saprotrophs, parasites feed on living hosts, though some parasitic fungi, for instance, may continue to feed on hosts they have commensalism and mutualism, the parasitic relationship harms the host, either feeding on it or, as in the case of.
Biological control or biocontrol is a method of controlling pests such as insects, mites, weeds and plant diseases using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management can be an important component of integrated pest management (IPM) programs.

They probably fed on plants like Cordaitales or their soft bodies, aphids do not fossilize well, and the oldest known fossil is of the species Triassoaphis cubitus from the : Insecta.

Biological diversity (biodiversity) encompasses the variety of life forms occurring in nature, from the ecosystem to the genetic level, as a result of evolutionary history (Wilson ).The idea that fungi form a kingdom distinct from plants and animals gradually became accepted only after Whittaker ().Presently, the “fungi” as a mega Cited by: Aphids-wise things are of course also slow.
Perhaps more than some years the slow spring has highlighted which aphids are really early-season opportunists, and which might be less worried about an early start. I have collected some shoots of important woody host plants and attempted to root cuttings in the greenhouse.
Introduction. Aphids, as a group, represent some of the most damaging insects to agriculture in the world. They were the subject of numerous research studies, and the topic of many books, including Dixon,Dixon,Harris and Maramorosh,Minks and Harrewijn,Blackman and Eastop,and van Emden and Harrington ().While it is difficult to Cited by: 1.
Description: The male's chunky white body (about 5 cm long), combined with the brownish-black bands on its otherwise translucent wings, give it a checkered look. Females have a brown body, and are less noticeable, though they have a similar wing pattern.
The Common Whitetail can be seen hawking for mosquitoes and other small flying insects over ponds, marshes, and slow. Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP -i- DOP -tər-ə, from Ancient Greek lepís “scale” + pterón “wing”) is an order of insects that includes butterflies and moths (both are called lepidopterans).

This was based on the principle that if a proportion of the population was marked in some way, returned to the original population and then, after complete mixing, a second sample was taken, the number of marked individuals in the second sample would have the same ratio to the total numbers in the second sample as the total of marked Cited by: 5.
