Effects or Economic Importance of Insect Pests in Crop Production.

Calomys musculinus There are more than 4000 species of mammals, of which about 1700 are rodents (Anderson and Knox Jones 1967). Rodents destroy at least one percent of the world's cereal crops on an annual basis. The economic importance of rodent pests.

They destroy other property, for example, by causing fires by gnawing the insulation from electrical wiring. Apart from the fixed costs associated with crop production, such as field preparation, seed, and, in some systems, variable costs such as fertilizer use, there is a cost The management problem is to specify the timing and application of (

However, the three imported, commensal rodents are far more destructive to man and

There are three major reasons why rats and mice are considered pests: They consume and damage human foods in the field and in stores. Introduction. © 2020 Ecological Society of America. Indeed, our analyses suggest that current governmental funding for rodent pest control should be devoted instead to research, especially in developing countries. We thank Charles Krebs for his comments on this manuscript. When the rodents eat their mushrooms, they distribute the fungal spores in their scat, facilitating another generation of healthy forest.Jennifer Mueller began writing and editing professionally in 1995, when she became sports editor of her university's newspaper while also writing a bi-monthly general interest column for an independent tourist publication. In the previous reports on the ectoparasites of rodents in different parts of Iran, various species of ectoparasites have been occurred, most of them with medically or veterinary importance. These groups of insect pests include:Rice weevil (Sitophilus oryzae), stem borers, army worms and leaf rollersMaize weevils (sitophilus zea), stem borers and army wormsStem borers, root mealy bug, aphids, black tea thrips, and scalesEffects or Economic Importance of Insect Pests in Crop ProductionInsect pests destroy crops in the field through their biting, chewing, boring, sucking and defoliation activitiesThey cause reduction in the viability of stored produceSite of injuries by insects may predispose crops to disease attackThey increase the cost of production during the course of controlling themThey render vegetables and fruits unattractive and unmarketableThey reduce the quality of produce either in the store or in the fieldPests of crops can be prevented or controlled through the following methods:A plant disease may be defined as a departure or deviation of the plant from the normal state of health, presenting marked symptoms or outward visible signs.

At least one African rodent, the Kivu giant pouched rat, has an equal responsibility in encouraging plant growth by dispersing seeds. The higher the abundance of voles in autumn, the greater the over‐winter density decline (Control of Brandt's voles currently depends on the use of non‐specific lethal baits. Habitat selection of the Black-shouldered Kite Some spend all their time high in trees, while others live underground and seldom venture above the surface.

These diverse creatures live on all major continents except Antarctica, as well as most islands.

Unfortunately, ecologists tend to ignore economics, economists typically have a simplistic understanding of ecology, and pest control managers commonly underrate both.
