Insect - Insect - Damage to growing crops: Insects are responsible for two major kinds of damage to growing crops. First is direct injury done to the plant by the feeding insect, which eats leaves or burrows in stems, fruit, or roots. There are hundreds of pest species of this type, both in larvae and adults, among orthopterans, homopterans, heteropterans, coleopterans, . Plant pests and diseases Australia is lucky to be free from many of the world’s most damaging plant pests. Exotic plant pests are capable of damaging our natural environment, destroying our food production and agriculture industries, and some could change our way of life.
certain crops has resulted in the development of pest resistance to pesticides (see ), pest resurgence, the development of secondary pests into major pests, an increase in pesticide use, an increase in production costs, and uneconomic crop production. These effects have resulted in production of those crops being abandoned, as well as the.

Recent studies suggest that the production of major commodities has declined since due to global warming (Lobell et al. ). It is estimated that, given current warming trends in sub-Saharan Africa, the production of major cereals could decline by as large as 20% by mid--century (Schlenker and Lobell ).

Crop losses due to weeds, animal pests (arthropods, nematodes, mammals, slugs and snails and birds), fungal and bacterial pathogens, and viruses were estimated from literature data.
Oerke et al. () was used as source of primary data on the crop loss situation as well as loss estimates by pest group. Literature searches in and were Cited by: Crop losses caused by pests, including rodents and birds, and by diseases and weeds, are defined, and previous studies reviewed.
Information about losses is needed to monitor the effects of pests and diseases on crop production, in individual countries and worldwide, important for food policy and economic reasons; to make decisions and allocate resources on the study, Cited by: Virus and viroid diseases are one of several factors accounting for loss in crop yields.
Crop loss assumptions and loss estimates are necessary before the economic impact of a disease is established and the economic advantages of Author: K. Subramanya Sastry. Crop loss assessment due to armyworm is also measured by assigning the score of pest infestation on the leaves with the help of standardized score charts.
The number of grades of such score charts may vary from pest to pest for different crops; usually it indicates the percentage damaged area of the leaves (Dent, ). vention and control of crop losses due to pests in the field (pre-harvest losses) and during storage (post-har-vest losses).
This paper concentrates on pre-harvest los-ses, i.e. the effect of pests on crop production in the field and the effect of control measures applied by farmers in order to minimise losses to an acceptable level (Oerke ).Cited by: Yield losses of wheat, maize, cotton and rice crops due to biotic factors (pests, diseases, and weeds) in  are depicted in Figure 1.

The term yield loss should be restricted to describe the reduction in yield caused by a single pest. Direct. A global review of issues in crop production and crop protection is presented, providing estimates of losses in the major food and cash crops. An overview is provided of world agricultural resources and their use, and the implications of rapid population growth are analysed.

Crop losses, or more specifically yield losses, occur because the physiology of the growing crop is negatively affected by pests in a dynamic way over time as crop both grows (i.e., increases in biomass) and develops (i.e., passes through the different stages of its physiological development).
