Project description:Background: The horn fly, Haematobia irritans (L.), is an obligate blood-feeding parasite of cattle and control of this pest is a continuing problem in the United States and other parts of the world. Worldwide annual economic losses attributable to this pest surpass $1 billion. The fly is becoming resistant to pesticides and new control technologies are needed by cattle producers. Results: Dominant conditional lethal gene systems are being investigated as population control technologies against agricultural insect pests. One of the critical components of these systems is a highly expressed female-specific gene promoter which can be used to drive expression of a lethality-inducing gene. To identify candidate genes to supply this gene promoter, microarrays were designed from a recently developed horn fly EST database and probed to identify female-specific and larval-specific differential gene expression. Analysis of dyeswap experiments found 432 and 417 transcripts which were over- and under-expressed in adult female flies, respectively, compared to adult male flies. Additionally, 419 and 871 transcripts were over- and under-expressed in first instar larvae compared to adult flies. Three transcripts were identified which were over-expressed in adult females flies compared to adult males and which also were over-expressed in the first instar larval lifestage compared to adult flies. Conclusion: We have identified 3 strong candidates for further evaluation as a gene promoter source for the development of a female-specific conditional lethality system in the horn fly. One of these candidates, the putative nanos orthologue, has a high female-to-male expression ratio, has a moderate expression level in first instar larvae, and has been well characterized in D. melanogaster. Further investigations leading from this microarray analysis will include transformation of the horn fly and evaluation of the female conditional lethal system components for applicability to the specific biological parameters of natural populations of the horn fly.

Project description:A key feature of Nasonia are their form of sex determination, called haplodiploidy. Females are diploid and develop from fertilized eggs, whereas males are haploid and develop parthenogenetically from unfertilized eggs. This form of sex determination is exploited by this experiment, by knowing the sex of the organisms from the earliest stages of development, so to trace the transcriptomes of sexual development of an insect. We conducted three replicates each using RNA from independent biological extractions of male and female early embryo (0-10 hrs), late embryo (18-30 hrs), 1st instar larvae, and pupae. Additional experiments were performed comparing transcription in adult males, adult females, testis and the female reproductive tract.
