        <dc:description>Diapause is an endocrine controlled arrested metabolic state to delay development or reproduction&#13;
under unfavorable conditions. To gain an understanding of importance of diapause for ecological&#13;
adaptation, it is important to study regulation of diapause in insects. We examined genetics of&#13;
diapause in Chilo partellus by crossing the hibernating (HD), aestivating (AD), post-hibernating (PHD),&#13;
post-aestivating (PAD), and nondiapause (ND) strains. Reciprocal crosses were also made to gain&#13;
full understanding of diapause regulation and the maternal effects, if any. Data were recorded on&#13;
fecundity, egg hatching, larval survival, diapause induction and termination, adult emergence, and&#13;
morphometrics of larvae, pupae and adults in the parents (P1, P2), F1 hybrids, and the reciprocal crosses.&#13;
Genetic analysis showed that AD strain is general combiner, which also improved egg hatching, larval&#13;
survival, diapause termination, adult emergence and proportion of females in the progenies. Incidence&#13;
of diapause was highest in HD × AD, whereas termination was greatest in PHD × AD. However, ND&#13;
strain and its reciprocal crosses with other strains did not exhibit any noticeable developmental&#13;
response associated with diapause. Specific combining ability analysis suggested that where PHD and&#13;
AD strains exist together there will be likely reduction in diapause incidence, increased survival with&#13;
greater fitness and faster multiplication of their progenies resulting in outbreak of C. partellus. Degree&#13;
of dominance estimates revealed that diapause, developmental and morphometric traits in C. partellus&#13;
are governed by over dominance gene effects, and mainly depend on parental diapause history.</dc:description>
