The persistence of Heterorhabditis megidis in soil was studied over a 4-week period. On days 0, 2, 14, and 28, infective juveniles (IJ) were extracted by centrifugal flotation, Baermann funnel, and baiting of soil with Tenebrio molitor larvae, which were then dissected. Extraction efficiencies on day 0 were 82% by centrifugal flotation, 56% by Baermann funnel, and 19.8% by bait insect. The rela...

Although Talon® baits containing brodifacoum have been used successfully in eradicating rats from some of New Zealand's offshore islands, little is known about any environmental effects of this toxin. Invertebrates, blackbirds, soil, and water at intervals of two days to nine months were sampled to determine whether brodifacoum residues were present after aerial distribution of Talon® 20P cerea...

Soils with specific suppressiveness to plant-parasitic nematodes are of interest to define the mechanisms that regulate population density. Suppressive soils prevent nematodes from establishing and from causing disease, and they diminish disease severity after initial nematode damage in continuous culturing of a host. A range of non-specific and specific soil treatments, followed by infestation...

conglomeration of an array of well established fields, such as microbial genomics, phylogenetics, forensic informatics and classical microbiology. Unlike public health investigations, microbial forensic investigation goes further to associate the source of the causative agent with a specific individual or group. Microbial forensics will be most effective if there is sufficient basic scientific ...

Four rodent control techniques-sustained baiting (SB) with cournachlor. pulsed baiting (PB) with brodifacoum. a lethal electrified barrier (LEB), and a nonlethal electrified barrier (NLEB)-were evaluated on the experimental fann of the International Rice Research Institute (IRRI) in the Philippines. A fifth treatment (no experimental rodent control) was established for reference. Mean tiller da...

Hematophagous arthropods transmit the etiological agents of numerous diseases and as a result are frequently the targets of sampling to characterize vector and pathogen populations. Arguably, the most commonly used sampling approach involves traps baited with carbon dioxide. We report results of a laboratory study in which the performance of carbon dioxide-baited traps was evaluated using measu...

This paper discusses the development of site-specific baiting technology for controlling the house mouse (Mus musculus) in confined swine facilities utilizing specific rodenticide formulations, bait stations, and baiting strategies. Behavioral research was also conducted to identify primary nesting and travel activities of mice within grower-finishing units. The rodenticide bromadiolone in a bl...

Forty eight soil samples were collected from 12 garbage waste soils of Ranchi, Jharkhand and screened for presence of keratinophilic fungi using hair baiting techniques for isolation. Fungal growths appearing on the baits after two to four weeks of incubation at room temperature were microscopically examined and cultured on mycological media. Cultures were then identified on the basis of coloni...

Abstract Background Trichoderma asperellum (Ascomycota: Hypocreaceae) is a globally recognized soil fungus due to its broad-spectrum antimicrobial and plant growth-promoting properties. To increase the availability of local strains, samples from dragon fruit farm in Villanueva (Misamis Oriental, Philippines) were collected baited using insect-baiting technique. Results Using baiting technique, ...
