Abstract Gypsy is an endogenous retrovirus of Drosophila melanogaster. Phylogenetic studies suggest that occasional horizontal transfer events of gypsy occur between Drosophila species. gypsy possesses infective properties associated with the products of the envelope gene that might be at the origin of these interspecies transfers. We report here the existence of DNA sequences putatively encoding full-length Env proteins in the genomes of Drosophila species other than D. melanogaster, suggesting that potentially infective gypsy copies able to spread between sexually isolated species can occur.

The introduction of the Asian gypsy moth into novel environments continues with frequent interceptions in North America. There is a concern that these subspecies will pose a greater threat to the forests and urban environments of North America than the established gypsy moths (Lymantria dispardispar L.), due to their greater capacity for female flight. Asian gypsy moth populations vary in many key traits, including female flight capabilities. The potential impacts of female flight, in combination with the other key traits, on the ecology and spread of this insect are first discussed in this co

Previously we have shown that yellow enhancers can overcome inhibition by a downstream insulator in the yrh1 allele, when a second gypsy element is located upstream of the enhancers.

Abstract:

We studied the effect of mutations at the suppressor of forked [su(f)] locus in Drosophila melanogaster on the accumulation of transcripts encoded by the gypsy transposable element. Mutations at this locus do not affect the pattern of developmental expression of gypsy, but they cause an increase in the total amount of gypsy RNA present at different stages of development as compared with wild-type or su(f)/+ flies. These results suggest that the su(f)-encoded products acts as a negative regulator of gypsy expression.

Abstract We collected data on mortality of late-instar gypsy moth, Lymantria dispar (L.), from outbreak populations over 4 wk in June 2017 at 10 sites in the New England region of the United States, along with estimated rainfall at these sites. Deposition of airborne conidia of the fungal pathogen, Entomophaga maimaiga Humber, Shimazu & R.S. Soper, was measured at these same sites as well as at seven other locations in New England. We also quantified the geographical distribution of gypsy moth-caused defoliation in New England in 2017 and 2018 from Landsat imagery. Weekly mortality of gyps

Abstract:

For many centuries, Roma/Gypsy people have been an oppressed and stateless minority. Until 1989 most Roma/Gypsy people resided in the former Central and Eastern European communist countries. After the fall of the Berlin Wall, the Roma/Gypsy became one of the communities that were regarded as a scapegoat for post-Communist society's ills. Despite much rhetoric to the contrary, Roma/Gypsy communities were not welcomed in the West and much of the persecution they endured in the East they saw repeated in the West.

Abstract:

Abstract The gypsy retrovirus invades the germ line of Drosophila females, inserting with a high frequency into the ovo locus. Gypsy insertion sites in ovo are clustered within a region in the promoter of the ovo gene that contains multiple binding sites for the OvoA and OvoB proteins. We found that a 1.3-kb DNA fragment containing this region is able to confer gypsy insertional specificity independent of its genomic location. The frequency of gypsy insertions into the ovo gene is significantly lower in wild-type females than in ovoD1 females. In addition, gypsy insertions in ovoD1 females occ

Abstract:

ABSTRACT The Suppressor of the Hairy wing [Su(Hw)] binding region within the gypsy retrotransposon is the best known chromatin insulator in Drosophila melanogaster. According to previous data, two copies of the gypsy insulator inserted between an enhancer and a promoter neutralize each other's actions, which is indicative of an interaction between the protein complexes bound to the insulators. We have investigated the role of pairing between the gypsy insulators located on homologous chromosomes in trans interaction between yellow enhancers and a promoter. It has been shown that trans activati

Abstract We investigated the effect of gypsy moth (Lymantria dispar L.) larval abundance on annual radial growth of preferred, intermediate, and avoided host trees: northern red oak (Quercus rubra L.), sugar maple (Acer saccharum Marsh.), and white ash (Fraxinus americana L.), respectively. Individual trees were surveyed for gypsy moth larvae from 1979 to 1992 in a chronically infested forest on a drought-prone site in southwestern Québec. Increment cores were collected from 156 oaks, 39 maples, and 39 ash, and annual radial growth indices from 1950 to 1992 were calculated for each species. Gr

In this study, manufactured a gypsy composite ceiling of a Sumbawa sisal fiber with a faction composition of the volume of 65% of a gypsy, cement 29% and sisal fiber 6%. The direction of fiber is variated with four conditions namely continuous fibre (SC) fiber woven (SW), discontinuous fibre (SDC) and hybrid fiber (SH).

Abstract:

Mutations in the suppressor of Hairy-wing [su(Hw)] gene of Drosophila melanogaster can cause female sterility and suppress mutations that are insertions of the gypsy retrotransposon. Gypsy binds the protein (SUHW) encoded by su(Hw), and SUHW prevents enhancers promoter-distal to gypsy from activating gene transcription. SUHW contains 12 zinc fingers flanked by acidic N- and C-terminal domains. We examined the roles of each of the 12 zinc fingers in binding gypsy DNA and classified them into four groups: essential (fingers 6 through 10); beneficial but nonessential (fingers 1, 2, 3, and 11); un
