Cockroaches have been recognized for half a century as major triggers of respiratory disease, including allergies and asthma. The broad economic importance of fungi exists in the medical industry for curing diseases in humans and animals. Insects of economic importance A. Injurious insects a) Pests of cultivated plants ( crop pests) Each cultivated plant hatbours many insects pests which feed on them reduce the yield of the3 crop. Cockroach infestations can reach extremely high populations in homes and industrial/agricultural situations where they pose a risk from inhalant allergens. Economic importance of arthopoda. possibly including but not limited to the taxon's economic, ecological, or medical importance, striking appearance, abundance, or conservation status: . Female cockroach with ootheca. "Sanitation is the most important management tool for German cockroach control." Although German cockroaches can occur in individual homes, residents of these dwellings more often encounter one of the large cockroach species. The economic consequences of German cockroach infestations can be significant, especially in hotels, restaurants, supermarkets, and cruise ships. Protozoa includes acellular microscopic animals which have occupied almost all possible ecological habitats on the earth. Aggregation behavior and reduced locomotory activity in the German cockroach is known to be caused by chemical compounds in the feces. (eg) cotton bollworm, Rice stem bores. Also See: Hemiptera Family Key] GENERAL CHARACTERISTICS OF THE HEMIPTERA In the Hemiptera < Characteristics > only the Heteroptera are of medical importance. ADVERTISEMENTS: In this article we will discuss about various economic importance of protozoa. A recent study showed that the global mean infestation trend of B. germanica in human dwelling ranged from 40% to 70% [ 5 ]. Abstract. 1987. Six field-collected strains of B. germanica from Singapore were used to investigate resistance to fipronil and dieldrin. Cockroaches contaminated to 38 fungi species belonging to 19 families and 12 orders. Use of fire with oil (10g/m 3 ) as a physical control method was applied in 10 manholes and caused 99.7% and 76% reduction of P. americana after one and five months respectively.

They can be a direct cause of illness, pain, and suffering through bites and stings, infested wounds, or allergic reactions. Although agronomic and horticultural insects routinely disturb food production, their effects are relatively minor compared to the economic disruption, suffering, and death caused by medical pests. However, other countries have found the way to profit by not killing the insects, but by breeding them in special farms. Cockroaches damage food, dishes, packaging, clothing, and furniture and leave behind excrements and foul odors.

In most fishes, the flesh is white, contains about 13 to 20% of protein and has a food value of 300 to 1600 calories per pound. Field crops and horticultural crops are attacked by many insect species. Fortunately, of the 4,500 different species of cockroaches, 99.7 percent live in environments away from humans.Before you step on a cockroach, you might consider the benefits they provide to natural ecosystems as well as humans. Various ecosystem services provided by termites - their importance as a food resource for humans, wildlife and domestic animals - are discussed, along with the use of these insects in scientific research and in folk and traditional medicine.
