Analysis of Host Plant Resistance in Some Genotypes of Maize against Chilo Partellus (swinhoe) (pyralidae: Lepidoptera)
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...
متن کاملNitrogen Fertilizer Application in Maize and Its Impact on the Development of Chilo partellus (Lepidoptera: Pyralidae)
The current experiment was conducted to check the efficacy of different nitrogen doses on the bionomics of maize stem borer Chilo partellus (Lepidoptera: Pyrlidae) under laboratory and field conditions applied on three maize hybrids i.e., KK-8711, KWS-55 and KS-85. The results revealed that the body weight (mg) and frass weight (mg) of larvae positively correlated with nitrogen levels. There wa...
متن کاملCombining Ability among Twenty Insect Resistant Maize inbred lines Resistant to Chilo partellus and Busseola fusca Stem borers
A partial diallel design was used among 20 maize inbred lines to form 110 F1 hybrids to generate information on the values of these lines for developing insect resistant maize varieties during the short rains season of 2006. The hybrids were evaluated for resistance to the C. partellus and B. fusca, and for agronomic performance over two seasons during long and short rains of 2007 at a mid-alti...
متن کاملFactors Influencing the Adoption of Biological Control of Rice stem borer (Chilo Suppressalis) in Talesh Region, Iran
Among the agricultural crops, rice has had the largest share in pesticide use. Most of the croplosses are caused by the attack of Chilo suppressalis. The purpose of this study was toexamine effective factors on adoption of biological control by farmers in Talesh region ofIran. A survey study was conducted using a stratified random sampling to collect data fromfarmers in the selected rural areas...
متن کاملEffect of learning on the oviposition preference of field-collected and laboratory-reared Chilo partellus (Lepidoptera: Crambidae) populations.
Recent studies show that Vetiver grass, (Vetiveria zizanioides (L.) Nash), may have potential as a dead-end trap crop in an overall habitat management strategy for the spotted stem borer, Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). Vetiver grass is highly preferred for oviposition, in spite of the fact that larval survival is extremely low on this grass. The oviposition behaviour of fem...
