Download Rice Planthoppers: Ecology, Management, Socio Economics and by Kong Luen Heong, Jiaan Cheng, Monina M. Escalada PDF

By Kong Luen Heong, Jiaan Cheng, Monina M. Escalada

The e-book discusses planthopper pests of rice. those bugs are probably the most harmful pests, threatening nutrition safeguard all over the world. The old improvement of the rice planthopper challenge indicates that they're secondary pests and single-discipline keep watch over strategies or options weren't in a position to deal with them, and in its place triggered common resurgences. This booklet not just provides new ways to this power challenge, but additionally new ecological tools, new views at the influence of pesticide advertising, insights into constructing resistant forms and structural reforms in pest administration. Integrating organic, ecological, financial and sociological points, it truly offers the most recent info on newly built techniques for coping with this pest.

Dr. ok. L. Heong is the crucial scientist and bug ecologist on the foreign Rice examine Institute, Philippines. He has been discovering rice planthoppers for greater than 30 years. Dr. Heong is a fellow of the 3rd global Academy of technology and the Academy of Sciences, Malaysia.

Professor Jia-an Cheng is an insect ecologist who has been learning rice planthoppers for approximately 50 years. he's a professor at Zhejiang collage, China.

Professor M.M. Escalada works at Visayas kingdom University.

Less than continuous assault from either microbial pathogens and multicellular parasites, bugs needs to take care of immune demanding situations each day in their lives. even if, this has now not avoided them from changing into the main profitable crew of animals on the earth. bugs own highly-developed innate immune platforms which were fine-tuned via an palms race with pathogens spanning 1000s of thousands of years of evolutionary heritage.

The publication discusses planthopper pests of rice. those bugs are essentially the most damaging pests, threatening foodstuff defense worldwide. The historic improvement of the rice planthopper challenge exhibits that they're secondary pests and single-discipline regulate strategies or suggestions weren't capable of deal with them, and as a substitute prompted widespread resurgences.

As the operating scales are increasing, farmers pay more attention to cost/benefit analysis and would like to learn more about new technologies that could provide higher economic returns. The results from experiments using ecological engineering to manage rice planthoppers and other pests in Jinhua, Zhejiang Province have demonstrated that new techniques were more easily accepted and implemented in the larger production system. The long-term impacts of ecological engineering in restoring ecosystem resistance were easier to demonstrate in large farming systems.

However, unusual meteorological conditions often result in unusual immigration patterns, which could affect population development and increase variations in population size among years. For example, an outbreak of BPH and WBPH at the coastal area of the Bohai Sea in 1991, which was 1,500 km from the planthopper source area, resulted from a large scale and sustained Northward LLJ during 22 J. Cheng mid-July to early August, which transported the migrant population from Southern China (Jiangxi Province) to Northern China (Tianjing) (Feng et al.

Although parasitoids are usually selected over predators in classical biological programs and significant levels of parasitism of BPH eggs have been observed, predation primarily by spiders and the insects Microvelia douglasi atrolineata Bergroth and Cyrtorhinus lividipennis can effectively prevent BPH outbreaks in tropical rice ecosystems (Kenmore 1980; Kenmore et al. 1984). These predators are mainly generalists, which may show some advantages as well as disadvantages for controlling rice planthoppers since they could easily find alternative prey to maintain their persistence in the field when rice planthopper populations are low.
