Summary 1.Reproductive behaviour is routinely studied with a view towards characterizing how an animal responds to variation in resource abundance and quality. This characterization is less commonly made with respect to reproductive physiology. 2. In the Walnut-infesting Fly, Rhagoletis juglandis , ovarian development is cued by the presence of the host fruit resource. In this study, I examined how ovarian development was affected by two host characteristics that relate to competition in the juvenile stages: fruit size and presence of conspecific larvae. 3. Large fruit promoted egg maturation more than small fruit, and uninfested fruit promoted maturation more than larval-infested fruit. Both effects were reproduced with artificial models of fruit. 4. The functional significance of these effects and ramifications for individual-level dynamics in oviposition behaviour are discussed.

“…The discovery of TMOF Antigonadotrophins, or factors that inhibit egg development (oostatic hormones and TMOF), have been demonstrated in the cockroach Blattella germanica (Iwanov and Mescherskaya, 1935), decapod crustaceans (Carlisle and Knowles, 1959) and the housefly Musca domestica (Adams et al, 1968;Kelly et al, 1984). In mosquitoes, Meola and Lea (1972) and Else and Judson (1972) similarly demonstrated an ovary-produced humoral factor secreted during oogenesis that inhibited yolk deposition in less-developed follicles.…”

Trypsin-modulating oostatic factor: a potential new larvicide for mosquito control

Trypsin-modulating oostatic factor (TMOF), a mosquito decapeptide, terminates trypsin biosynthesis in the mosquito gut. The hormone is secreted from the ovary, starting 18·h after the blood meal, circulates in the hemolymph, binds to a gut receptor and stops trypsin biosynthesis by exerting a translational control on trypsin mRNA. Because of the unique primary amino acid sequence of the hormone (YDPAPPPPPP) and its stable three-dimensional conformation, TMOF is not degraded by gut proteolytic enzymes and can traverse the gut epithelial cells into the hemolymph of adults and larvae. Using this unique property, hormone fed to different species of mosquito larvae stops food digestion and causes larval mortality. To determine the shortest amino acid sequence that can bind to the gut receptor and still cause high larval mortality, 25 analogues of TMOF were synthesized and tested. The tetrapeptide (YDPA) was as effective as the decapeptide, indicating that the binding to the gut receptor is at the N-terminus of the molecule. Cloning and expressing the hormone on the coat protein of tobacco mosaic virus (TMV) in Chlorella sp. and Saccharomyces cerevisiae cells and feeding the recombinant cells to mosquito larvae caused larval mortality. These results indicate that TMOF can be used as a new biorational insecticide against mosquito larvae.

“…The observed relationships between the sizes of the last and penultimate oocytes demonstrated an apparent inhibition of the growth of the latter. This type of inhibition has been observed with Musca domestica [23], Aedes aegypti [24, 2 5], and with Phormia regina and Sarcophaga bullata [ 26]. Pappas and Fraenkel showed that the application of juvenile hormone to Phormia regina females stimulated the deposition of vitellus in the penultimate oocyte [ 26].…”
