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...

Sugarcane, Saccharum officinarum L., is one of the most economically important crop of Thailand. It is the main source of sucrose, and is used in sugar and alcohol production. Insect pest complex is the most important limiting factor in sugarcane production. Among the sugarcane insect pest complexes, the sugarcane moth borers complex is considered most important. Chilo infuscatellus Snellen, Ch...

The development of host races, genetically distinct populations of the same species with different hosts, is considered to be the initial stage of ecological speciation. Ecological and biological differences consistent with host race formation have been reported between water-oat and rice-associated populations of Chilo suppressalis. In order to confirm whether these differences have a genetic ...

Three new species of Chilo Zincken, 1817 are described and illustrated: agassizi Bassi, sp. n. from Tanzania, barpak Nepal gumaensis n Botswana.

Twenty available genotypes of maize were screened for resistance to Chilo partellus in the field. The genotype Sahiwal 2002 was found to be most susceptible while DK-6525 was most resistant. Maximum infestation was observed at the end of April while the minimum in the last week of March. Significant variations were observed in all the plant characters viz., number of nodes per plant, plant heig...

Online education has provided good opportunities for educationally disadvantaged people. However, some traditional learning management systems (LMSs), the base systems of online education, had the limitations in offering standardized education for diversified learners with different skills, objectives, abilities, preferences, and backgrounds. In addition, the traditional LMSs, which required a ...

DNA analysis of small insect iridovirus 6 was performed. Combined exonuclease-restriction endonuclease digestions revealed that all resulting fragments were degraded without preference for any one DNA fragment. Upon denaturation and reannealing of native linear Chilo iridescent virus DNA (158 x 10(6) daltons), duplex DNA circles of a smaller size (140 x 10(6) daltons) with protruding tails were...

The Chilo infuscatellus (Snellen; Lepidoptera: Pyralidae) is the main pest of sugarcane in China. The shortage of easily distinguishable morphological characters especially in early stage make it challenging to diagnosed and promptly take steps for pest management. In the present study, we described a PCR method for the molecular identification of based on barcode region of COI sequences betwee...

Asiatic rice borer, Chilo suppressalis (Walker), larvae cause extensive crop losses worldwide. Because chemical control is problematic, and sex pheromone applications are a valuable management tactic in China, judicious timing of a minimal density of pheromone dispensers is important in developing a cost-effective C. suppressalis IPM program. During June-October in 2011, 20, 30, 40, and 50 disp...
