This paper discusses the success of an unintended area-wide integrated pest management (IPM) for Chilo suppressalis in Japan. Chilo was considered as one of the country’s major rice insect pests causing significant yield loss during the pre-war period, along with Scirpophaga incertulas . Chilo population density declined through the years, which was considered to be induced by modern farming te...
Surveys were completed in Eritrea, Ethiopia, Kenya, Madagascar, Mozambique, Tanzania, Uganda and Zanzibar to assess the lepidopteran stem borer species diversity on wild host plants. A total of 24,674 larvae belonging to 135 species were collected from 75 species of wild host plants belonging to the Poaceae, Cyperaceae and Typhaceae. Amongst them were 44 noctuid species belonging to at least ni...
The sound-detection method of trunk borer is a very promising in the field forestry prevention and control borers. However, detection accuracy commonly used algorithms often decreases sharply case noise reverberation interference. In practical applications, sound monitoring borers takes place harsh acoustic environment. To solve this problem, we intend to introduce methods which are effective o...
This review reevaluates the importance of interspecific competition in the population biology of phytophagous insects and assesses factors that mediate competition. An examination of 193 pair-wise species interactions, repre senting all major feeding guilds, provided information on the occurrence, frequency, symmetry, consequences, and mechanisms of competition. Inter specific competition occ...
Decomposition of wood is an important part of the carbon cycle of nature. Decomposition is caused by fungi, insects, and marine borers that use the wood as food or shelter, or both. Lignin in wood provides a physical barrier to enzymatic decomposition of cellulose and hemicelluloses. This barrier is breached mechanically by insects and marine borers, biochemically by whiteand soft-rot fungi, an...
