VITELLOGENESIS IN A PRIMITIVE TERMITE,ZOOTERMOPSIS ANGUSTICOLLIS(HAGEN) (HODOTERMITIDAE)

Abstract

The sources and controls of egg storage proteins, the vitellins, have been subject to increasing attention in the past decade. Vitellogenesis offers an attractive model system in which large amounts of specific proteins are produced in a rela-PRIMITIVE TERMITE, ZOOTERMOPSIS ANGUSTICOLLIS (HAGEN) (HODOTERMITIDAE)."

Effect of Enhanced Dietary Nitrogen on Reproductive Maturation of the TermiteZootermopsis angusticollis(Isoptera: Termopsidae)

“…Colonies in two groups contained one pair of primary reproductives, whereas colonies in the remaining groups contained a pair of neotenic reproductives and three third-or fourth-instar larvae. Larvae were added to the latter colonies to ensure that reproductive maturation would occur, because isolated neotenics delay reproductive development (Greenberg et al 1978, Greenberg and Stuart 1979, Brent and Traniello 2001. Although the presence of three independent larvae is sufÞcient to promote the maturation of neotenics (Brent and Traniello 2001), the small number and size of the larvae limits their impact on the food supply, which could negatively inßuence female development (Lenz 1994).…”

Juvenile hormone binding proteins of termites detected by photoaffinity labeling: Comparison of Zootermopsis nevadensis with two rhinotermitids

“…angusticollis [30]. One of these proteins was shown to be the hemolymph JHBP, using the criterion of JH 111-cornpetable photoaffinity labeling by [3H]EFDA, which has been extensively exploited in characterization of insect JHBPs [31-331.…”

Influence of sex‐specific stimuli on ovarian maturation in primary and secondary reproductives of the dampwood termite Zootermopsis angusticollis

“…An increase in body mass may be due, in part, to increased water intake (Watson et al ., 1972), but should also be indicative of the increasing size and development of both the ovaries and the fat body. Assuming that the fat body is the primary source for egg vitellogenins for Z. angusticollis (Greenberg et al ., 1978), mass gain should be a correlate of a female's general nutritional state, and thus her ability to allocate energy toward rearing her first brood. The number of functional ovarioles comprising an ovary is indicative of a female's investment in her reproductive development and her potential capacity to produce eggs (Watson, 1972).…”

“…In several species of lower termites, the social stimuli that a female experiences following separation from her natal colony can affect both her reproductive behaviour and physiology. For example, primary females of Hodotermes mossambicus and Zootermopsis angusticollis Hagen will complete their reproductive maturation and exhibit reproductive behaviours only when isolated from their parent colony (Hewitt & Nel, 1969; Watson, 1972; Greenberg et al ., 1978; Greenberg & Stuart, 1979). After separation from the natal nest, additional social contact is usually necessary for primary females to complete their reproductive maturation, but the nature of the contact can vary between species.…”
