The results showed that the females of O. furnacalis began to lay eggs at 23:00, and the maximum number of eggs was laid during 2:00-3:00 a.m. in mono- and intercropping systems. The numbers of egg masses and eggs on abaxial leaf blade of maize monoculture, sugarcane monoculture and intercropped sugarcane were significantly higher than those on leaf blades, but no significant difference was found in the number of egg masses on the abaxial leaf blades and the leaf blades of intercropped maize. The numbers of egg masses on leaf veins were significantly higher than that on the leaf rims of monocultured maize and intercropped sugarcane, but no significant difference was found on intercropped maize and monocultured sugarcane, respectively. The number of eggs on leaf veins was significantly higher than that on the leaf rims of monocultured maize, monocultured sugarcane and intercropped maize. The leaf rims in intercropped sugarcane had more eggs than leaf veins. Most egg masses on abaxial leaf blades of monocultured sugarcane were on the sites with a distance of 69.14 cm from the leaf sheath base, and 21.09 cm from the leaf sheath base on leaf blade, and the egg masses were 35.17 cm and 12.34 cm from the leaf sheath on the abaxial leaf blade and leaf blade on intercropped sugarcane, respectively. The egg mass on the abaxial leaf blade of maize leaf from monocultured maize plants was far away from the leaf sheath base, but egg masses on abaxial and abaxial leaf blades of sugarcane leaves from the intercropped sugarcane were near the leaf sheath base. This study indicated that maize intercropped with sugarcane significantly affected the oviposition selectivity of O. furnacali. %K 亚洲玉米螟 玉米 甘蔗 间作 产卵行为< %K br> %K Ostrinia furnacalis (Guené e) maize sugarcane intercropping oviposition behavior %U http://www.zwbhxb.cn/ch/reader/view_abstract.aspx?file_no=20150102&flag=1
