Polyscelis Modestus Gahan, a Minor Parasite of the Hessian Fly
The hymenopterous parasite which is the subject of this paper was first reared from the Hessian fly (Phytophaga destructor Sav) in the summer of 1915 by the late W. R. McConnell and the author at the Hagerstown, Md., Laboratory of the Cereal and Forage Insect Investigations of the Bureau of Entomology, United States Department of Agriculture,, when a heavy infestation of that insect pest of whe...
متن کاملFly Genes That Help Devour a Fungal Parasite
Background: Uterine fibroids or leiomyoma are a common benign smooth muscle tumor. The tumor growth is well known to be estrogen-dependent. However, the molecular mechanisms of its estrogen-dependency is not well understood. Methods: Differentially expressed genes in human uterine fibroids were either retrieved from published papers or from our own statistical analysis of downloaded array data....
متن کاملA neo-sex chromosome that drives postzygotic sex determination in the hessian fly (Mayetiola destructor).
Two nonoverlapping autosomal inversions defined unusual neo-sex chromosomes in the Hessian fly (Mayetiola destructor). Like other neo-sex chromosomes, these were normally heterozygous, present only in one sex, and suppressed recombination around a sex-determining master switch. Their unusual properties originated from the anomalous Hessian fly sex determination system in which postzygotic chrom...
متن کاملNematode Parasite of Face Fly
New informat ion is reported on the parasit ism of Heterotylenchus autumnalis upon its principal known host, Musca autumnalis. Black to b rown spots are produced on the cuticle of all infected host larvae where the nematode penetrated. The principal damage to the host is castration of the female. In laboratory tests nematode larvae were not infective and did not leave the hosts before the femal...
متن کاملHessian Fly-Associated Bacteria: Transmission, Essentiality, and Composition
Plant-feeding insects have been recently found to use microbes to manipulate host plant physiology and morphology. Gall midges are one of the largest groups of insects that manipulate host plants extensively. Hessian fly (HF, Mayetiola destructor) is an important pest of wheat and a model system for studying gall midges. To examine the role of bacteria in parasitism, a systematic analysis of ba...
