Biological pest control

Microbial insecticides Introduction Pest management approach, methods and discipline have undergone developments and advancements with the progress of time to reduce environmental impacts. Microbial insect control uses pathogenic microorganisms isolated from diseased insects during naturally occurring outbreaks. Usually, such epidemics only occur when pest population densities are high and usually after significant damage have been done to crops [1], [2], [3]. Over 400 species of fungi and more

Substantial Content I. Importance of natural method of pest control The problem with broad range conventional pesticides is that they not only kill the bad bugs, but they rub out the good bugs, too. A garden without natural predators means a world of insects gone wild. There's nothing left to keep pest levels in check. In fact, chemicals can mean double trouble because although you wipe out the first wave of pests, the second wave which is not the usual pest, but another insect moving into the area can cause

to come. The book set the stage for the first real and effectual environmental movement. In 17 chapters, many of which can stand alone as essays, Carson develops a deceptively simple premise: the use and overuse of synthetic chemicals to control insect pests introduces these chemicals into the air, water, and soil and into the food chain where they poison animals and humans, and disrupt the many intricate

without their chemical control. In Egypt, Khidr et al. (1996) tested the efficacy of the pyrethroids, cypermethrin, cis-cyfluthrin, S-fenvalerate, fenpropathrin and cyhalothrin against P. gossypiella and E. insulana. They stated that, all insecticides gave a high degree of control against cotton bollworms and the treatment increased the yield of cotton significantly over the control, with s-fenvalerate being the best treatment. Aref (1997) evaluated the efficiency of integrated pest management programs

ABSTRACT: Coccidoxenoides perminutus

Cauliflower is the most popular vegetable in the whole world.it is a great green vegetable which is very good for our health.it is a term of cultivated plant.it also belong with the brassica family. Firstly cauliflower is a Latin word. Which meaning a great flower because, in the beginning it is belong Italy because Italy produce a large number of cauliflower production on that time.it is very familiar with the cabbage because it also belong to the brassica family. Therefore, both have a lot of similarities

this landscape are no longer visible, the water that used to ripple continuously is perfectly still. The wetland is dead, except for this overpowering, hardy purple flower that has choked out all other vegetation and species. Purple loosestrife now controls this landscape. Purple loosestrife is an exotic species that was introduced to North America from Europe during the early 1800's. Europeans sailing

safe for my family, pets, and plant life. My plan is to use non-toxic pest controls to ward off insects that do damage and spread disease. My plan will also consist of incorporating plants that encourage good insects that help my homes ecofriendly environment. My plan will consist of the following points: Goals My goals are to educate myself, family, friends, neighbors, and classmates on how to utilize safe natural pest controls and to ensure a safe sustainable environment. There are a number of

throughout the world and its usage is very common. There are thousands of different Bt strains. The kurstaki strain being the most common kills only leaf- and needle-feeding caterpillars. In the last ten years, Bt strains have been mostly used to control the abundance of flies, mosquitoes, black flies, amongst others. When it comes to Bt strains, the target is very specific. The strains for mosquitoes will only target them and not affect other insects. Even though Bt is used in aerial spraying programs

phenomena of resistance to the causal pathogens (Brewer and Larkin, 2005). Therefore, to overcome these difficulties, it is urgent to apply alternative safe efficient methods against such disease or at least rationalization their application. Biological control is considered an important approach of agricultural biotechnology in recent years for controlling many fungal plant pathogens. Both Bacillus and Trichoderma spp. are the most promising and effective bioagents against various plant pathogenic
