Previtellogenic ovaries of Athalia rosae (Hymenoptera, Symphyta, Tenthredinidae) were transplanted into the adult female abdominal hemocoel of Athalia infumata (Symphyta, Tenthredinidae), Arge nigrinodosa (Symphyta, Argidae), and Pimpla nipponica (Ap

We describe a simple and rapid method for cloning insect vitellogenin (Vg) cDNAs. The method relies on the facts that insect Vg amino acid sequences can be aligned confidently along their entire lengths and that a short, highly conserved GL/ICG motif

Fertilization by intracytoplasmic injection of mature sperm into mature eggs has previously been achieved in the sawfly, Athalia rosae (Insecta, Hymenoptera). In the present study, we examined the potential of spermatids, premature male gametes, for

A cDNA expression library constructed from poly (A)+ RNA prepared from vitellogenic female fat body cells of the American cockroach, Periplaneta americana (Dictyoptera) was screened using a polyclonal antiserum against the 100-kD polypeptide(s) from

The egg deposition behavior of the turnip sawfly, Athalia rosae (Hymenoptera: Symphyta), is described. Both unmated and mated females lay eggs individually inside of fresh young leaves of cruciferous plants. During an oviposition event, females exhib

The cDNA for vitellogenin (Vg) of the parasitoid wasp Pimpla nipponica (Hymenoptera: Apocrita) was cloned and sequenced. 1 The deduced amino acid sequence with 1807 residues was obtained. The N-terminal 20 amino acids chemically determined for vitell

Mature eggs of the sawfly, Athalia rosae (Hymenoptera: Symphyta: Tenthredinidae), contain two major yolk polypeptides, vitellins (Vn), derived from the corresponding haemolymph precursors, vitellogenins (Vg), (L-Vn and -Vg=180 kDa, and S-Vn and -Vg=5

Previtellogenic immature ovaries of Athalia rosae (Hymenoptera) were transplanted into the abdomens of adult male Athalia infumata hosts, which were then treated with juvenile hormone III topically to induce vitellogenin synthesis. The A. rosae oocyt

Sperm of the turnip sawfly Athalia rosae (Hymenoptera) were frozen in liquid nitrogen without cryoprotectant, and were stored for weeks at −80°C. The sperm, upon thawing, were non-motile and had abnormal morphology. They were, nevertheless, able t
Production of haploid-haploid chimeras by sperm injection in the sawfly, Athalia rosae (Hymenoptera)

Mature unfertilized eggs (oocytes) dissected from the ovary of the sawfly Athalia rosae (Hymenoptera) begin parthenogenetic development if exposed to distilled water and produce haploid males. Injection of sperm into mature oocytes through the anteri
