We provided a list of eleven taxa endo and ecto parasites associated with nine species anoles Ecuador. The identified in laboratory are: nematodes the family Ascarididae Anolis dracula, A. trachyderma scypheus; larvae genus Cochliomyia spp. (Calliphoridae) parvauritus; mites Trombiculidae nemonteae gracilipes.

Behavioural responses of an animal are variable even when the animal experiences the same sensory input several times. This variability can arise from stochastic processes inherent to the nervous system. Also, the internal state of an animal may influence a particular behavioural response. In the present study, we analyse the variability of visually induced head pitch responses of tethered blow...

The significance of brushtail possum, Trichosurus vulpecula Kerr (Diprotodontia: Phalangeridae) carcasses to the succession and production of Diptera species and its relevance to fly strike management in Tasmania, Australia was examined. Calliphora stygia (Fabricius), Lucilia sericata (Meigen) and Calliphora vicina Robineau-Desvoidy (Diptera: Calliphoridae) were found to be the most abundant an...

Seasonal rhythms have been found in practically all groups of insects, but Diptera they studied to a lesser extent. In deciduous forests the European part Russia (Republic Mordovia, Temnikov district) seasonal dynamics abundance was 9 families (Tipulidae, Lonchaeidae, Aulacigastridae, Milichiidae, Heleomyzidae, Anthomyiidae, Muscidae, Fanniidae, Calliphoridae). Two peaks were characteristic Tip...

Necrophagous insects, mainly Diptera and Coleoptera, are attracted to specific stages of carcass decomposition, in a process of faunistic succession. They are very important in estimating the postmortem interval, the time interval between the death and the discovery of the body. In studies done with pig carcasses exposed to natural conditions in an urban forest (Santa Genebra Reservation), loca...

A survey of the carrion fauna was made at two sites in Curitiba, State of Paraná, with the objective of describing the insects associated with carrion and setting up a preliminary data-base for medico-legal purposes in south Brazil. Vertebrate exclusion experiments were carried out in each season between 1994 and 1995 with a 250 g laboratory-bred rat (Rattus norvegicus). Five stages of decompos...

We combined two models to investigate the theoretical dynamics of five exotic and native blowfly species in response to the Allee effect by using demographic parameters estimated from experimental populations. Most of the results suggest stabilization of dynamic behavior in response to the Allee effect. However, the results depended on the magnitude of the demographic parameters of each species...

Calliphorin, Insect Cuticle, Immunofluorescence, Calliphora vicina Injections of radioactively labelled calliphorin into Illrd instar larvae of Calliphora indicate that the protein is incorporated into the integument. Immunofluorescence techniques show that the endocuticle is the Final site of deposition of calliphorin. It is concluded that calliphorin is an essen­ tial protein of the tanned cu...

This paper is concerned with a class of Nicholson’s blowflies models with a nonlinear density-dependent mortality term. We use coincidence degree theory and give several sufficient conditions which guarantee the existence of positive periodic solutions of the model. Moreover, we give an example to illustrate our main results.

A preliminary, systematic field study on the process of decomposition and associated insects was conducted, for the first time, in New Zealand. Using pig carcasses as an animal model for human decomposition, insect colonisation and succession was monitored in three different habitats in the Auckland region where remains are likely to be found. A significant difference in the rates of decomposit...
