The tephritid fly Zonosemata vittigera (Coquillett) has a leg-like pattern on its wings and a wing-waving display that together mimic the agonistic territorial displays of jumping spiders (Salticidae). Zonosemata flies initiate this display when stalked by jumping spiders, causing the spiders to display back and retreat. Wing transplant experiments showed that both the wing pattern and wing-wav...

As you may recall, the house fly (Musca domestica) white paper was submitted to NHGRI twice before. The last version was enthusiastically supported by the working group, but did not receive approval from the Coordinating Committee. I discussed this matter with Dr. Felsenfeld who suggested that we revise the proposal where we felt it was necessary, but that we focus our efforts on a letter to yo...

background: combination of cyromazine as an insect growth regulator (igr) and nasonia vitripennis (hymenop tera: pteromalidae) a parasitic wasp may be an effective tool for reducing the house-fly populations in poultry houses and livestock farms. this study was conducted to assess the side effects of the igr cyromazine on the level of parasit ism and numbers and the longevity of emerged n. vitr...

Mechanical barriers consisting of bands of polyethylene terepthalate resin attached to wooden posts by latex caulk adhesive and staples were 100% effective in preventing passage of dispersing lesser mealworm, Alphitobius diaperinus (Panzer), larvae in the laboratory. Barriers continued to be 100% effective after beinig held in a caged layer poultry house for 3 mo. Polyethylene terepthalate barr...

Bacterial distribution in different developmental stages of house fly Muscadomesticavicina revealed that in the majority of maggots and prepupae, the hemolymph is sterile. Fat cells and trachea are like-wise sterile. Bacteria was distributed through the digestive tract of immature stages of the fly. In larvae/ the largest bacterial count was found in the fore gut then the hind gut and lastly th...

A bacterial formulation containing spores of a Brevibacillus laterosporus strain from Sardinia, known to be toxic by ingestion to the house fly (Musca domestica), was assayed in laboratory, outdoor, and field conditions for the control of immature stages of this pest. In all laboratory assays, the bacterial formulation exhibited toxicity against house fly larvae. A concentration of 1 x 10(8) sp...
