| Channel 1 |
| Source name |
Testes collected from yellow body red-eye stage males
|
| Organism |
Nasonia vitripennis |
| Characteristics |
Sex: male
developmental stage: pupa
tissue: testes
strain: AsymCX
|
| Treatment protocol |
Samples were prepared at 25º C as follows: Approximately 200 N. vitrirpennis (AsymCX) virgins were collected as black pupa. When eclosed, half of them were provided with males and were allowed to mate overnight, and the other half were kept as virgins. Virgin setting result in all-male progeny whereas mated females produced ~89.5% female progeny under the design used here. Females were provided 15- 20 Sarchophaga bullata hosts in groups of 20 females for 24 hrs to induce production of eggs. The hosts were then removed and females were left overnight (~18 hrs). To collect embryos, individual females were given access to a host at one end (to restrict the oviposition site) and allowed to lay eggs for 6-10 hrs before being removed. Embryos were then harvested immediately (early embryos), 18 hrs later (late embryos), or 51 hrs later (1st instar larvae). All embryos and larvae were collected in an RNase-free environment. The host was cracked open and the "cap" removed to expose embryos. Dissecting needles were used to gently scrape embryos from the surface of the host and transfer them into a 1.5 ml tube pre-chilled on dry ice. Samples were stored at -80º C. If at anytime the host was punctured or embryos were exposed to host hemolymph, they were discarded. Estimates of the number of embryos per replicate (three per life stage/sex) were recorded; early embryos ranged from 300-900, late embryo 140-500, 1st instar larvae 245-520. Since sex cannot be determined at larval stage, some of the mated female hostings were allowed to mature to adulthood then males and females were counted to determine the sex ratio. Early larvae showed an average of 82.9% females and late larvae had an average of 84.2%. Pupae collections were made among the progeny of mated females provided with hosts for 48 hrs. They were sorted by sex and stage (early yellow, red-eye, half black, and black pupae). Equal numbers (S20) of pupae from each stage were then pooled prior to RNA extraction. Males and females were extracted separately. Male reproductive tracts (testes, seminal vesicles, and accessory glands) were dissected in phosphate buffered saline (PBS) from and transferred with a small amount of PBS into a tube on dry ice. A total of 60 testes per replicate were dissected (10 each yellow/red, salt & pepper, and black pupal stages). Female reproductive tracts (30 per replicate) were removed from 1-3 days post eclosion virgin females and transferred to a tube on dry ice.

| Growth protocol |
Ovaries collected from females 24 hours after eclosion; testes collected from male pupa.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Tissue was homogenized using Trizol reagent (Invitrogen) and extracted RNA was purified using the Qiagen RNeasy protocol with on-column DNase treatment from specific tissues. Total RNA amplified using MessageAmp II aRNA Kit (Ambion). aRNA converted to ds cDNA using SuperScript cDNA Synthesis Kit (Invitrogen).
