“…This suggests that wing-forms are determined by a pair of allelo-morphic genes. Thus far, only a few crossing experiments suggest genetic regulation of wing-form density response in this species (Nagata & Masuda, 1980;Saxena et al, 1981). Our results of reciprocal crossings and back cross tests partly support the view that the brachypterous form is homozygous dominant and the macropterous form is homozygous recessive.…”

“…comm.). Significant increases in macroptery in the Philippine populations are caused by rearing on senescent rice plants (Saxena et al, 1981). The two strains, H and I, which were caught as macropters in the field, exhibited predominantly brachypterous characters at the next generation.…”

“…N. lugens shows wing-form dimorphism, having brachypterous and macropterous adults, mostly depending on densities during nymphal stages (Kisimoto, 1956(Kisimoto, , 1965Watanabe, 1967;Iwanaga et al, 1985). The responses to densities have been suggested to be under genetic control (Mochida, 1975;Nagata & Masuda, 1980;Kisimoto, 1981;Saxena et al, 1981). This was confirmed by Iwanaga et ai.…”

“…9 9 produced in field populations are reported to vary according to the degree of nymphal crowding during the early instars (Johno, 1963;Mori & Kiritani, 197I;Ohkubo, 1967;Takagi, 1972;Watanabe, 1967), the age and nutritional status of the host plant (Saxena et al, 1981) or a combination of both (Kisimoto, 1956;1965). Genetic factors are also involved in the wingmorph determination of L. striatellus (Mahmud, 1980).…”
