| dc.description.abstract | The population patterns
of eggs, larvae and puparia on bean plants and leaf punctures made by adults were investigated during cropping
(March-July; October-January) and noncropping (July-October) seasons
at two sites in Kenya. Bean grown in noncropping seasons had more
leaf punctures, eggs, larvae and puparia than
bean grown in cropping
seasons. Bean sown in noncropping seasons attracted unusually high
beanfly populations from surrounding weeds as well as previous crops.
Under field conditions, the Onhiomyi
beanfly species, sencerella
Greathead and 0. phasepli Tryon, bean
infested plants in all seasons. Both species normally oviposited in punctures on the leavesbut 0. spencerella also oviposited in the
stems of bean seedlings. | en |
