Hakomori T, Tanaka S (1992) Genetic control of diapause and other developmental traits in Japanese strains of the migratory locust, Locusta migratoria L.:
univoltine vs.
An obligatory characteristic of
univoltine species is a long diapause period during certain development phases.
A response of five pea varieties (Pisum sativum L.) to damage degree of Bruchus pisorum L., a
univoltine bruchid similar to B.
fluminea exhibited a
univoltine spawn cued by increases in temperature.
calidus appears to be employing a
univoltine Type I breeding strategy (22) with incubgtion and larval development completed in a matter of weeks.
After a period of oviposition, the adult weevils disappear, suggesting the species is
univoltine. The larvae within pods consume seeds for nutrition, often devouring all within a pod.
Currently, a
univoltine life cycle is assumed for D.
All other species examined are essentially
univoltine and this time period would have covered the entire life-cycle from emergence; for this P.
This species has a
univoltine life cycle and produces a total of 11 instars.
The life cycle is
univoltine and the adults overwinter in the litter (Hight et al.
Theoretical P/B values of 5 and 10 were used for several taxa considered to be
univoltine and bivoltine, respectively (Waters 1977, Lugthart and Wallace 1992).
