Background Enterobacter cloacae bacterium is a known symbiont of the most Anopheles gut microflora and nominated as a good candidate for paratransgenic control of malaria. However, the population dynamics of this bacterium within An. stephensi and its introduction methods to the mosquitoes have not yet been explored. Methods Enterobacter cloacae subsp. dissolvens expressing green fluorescent ...

BACKGROUND The potential role of oral vaccination of dogs against rabies in the Philippines was investigated in terms of safety and efficacy. METHODS Prior to the vaccination campaign, a house-to-house survey was carried out to collect data on the dog population in the study area, the coastal village of Mindoro. During the vaccination campaign all households were visited again, and all dogs e...

The use of toxic bait to kill adult Aedes albopictus is a safe and potentially effective alternative to the use of synthetic chemical insecticides. This study was carried out to determine effective concentrations of boric acid needed in sugar bait solutions applied to plant surfaces, and to determine its residual effect in reducing adult mosquito densities. In outdoor tests in 1,100-m3 screened...

In these simulations, there were no rules restricting the number of ants at baits; thus, no structuring mechanism is implied. Individuals were assigned to species using all three (even, skewed, and realistic) abundance frequency distributions. In model Null 1, for a species to be classified as dominant, it had to meet both the abundance and monopolization dominance descriptors. In Null 2a and N...

Insect carrion communities vary among habitats and over time. Concerning the dipteran early colonizers of carrion, the use of small bait traps should be accurate because the odors emitted from meat baits should contain many of the volatile organic compounds emitted from the freshly dead mammals. In addition, this kind of trap is easy to replicate and set in position in a given habitat. In the p...

Effective control of terrestrial wildlife rabies seemed almost impossible in Europe until the development of oral vaccination. Nowadays, oral vaccination of foxes (Vulpes vulpes) by distributing vaccine baits is the method of choice in rabies control in most European countries. Consequently, large areas are now rabies-free and here baits are no longer distributed or the distribution of baits is...

We developed a fast and simple method to detect presence or absence of DRC-1339 (CPTH: 3-Chloro-p-toluidine Hydrochloride) in birds that fed on DRC-1339 bait sites. We compared the effectiveness of the colorimetric method to the previously published analytical method using birds collected from DRC-1339 bait sites in Louisiana and Texas. We also conducted tests with caged red-winged blackbirds (...

Conditioned food or flavor aversion has been proposed as a method to stop coyote predation on sheep. The method entails treating sheep carcasses or meat baits with an emetic, lithium chloride (LiCl), and scattering them on sheep ranges. Theoretically, coyotes eat the baits, become ill, and subsequently desist from killing and eating sheep because they associate sheep flavor with sickness. In re...

Fascioliasis, a snail-borne parasitic zoonosis, has been recognized for a long time because of its major veterinary and human impact. Different Bait formulations were fed to the snail Lymnaea acuminata in clear glass aquaria having diameter of 30 cm. Snail attractant containing bait formulations was prepared from different binary combination (1 : 1 ratio) of carbohydrates (glucose, starch 10 mM...

Elasmobranchs can detect minute electromagnetic fields, <1 nV cm(-1), using their ampullae of Lorenzini. Behavioural responses to electric fields have been investigated in various species, sometimes with the aim to develop shark deterrents to improve human safety. The present study tested the effects of the Shark Shield Freedom7™ electric deterrent on (1) the behaviour of 18 white sharks (Carch...
