“…In addition, methods of obtaining data may influence findings. Reports from poison information centres (Haliburton and Buck 1983;Jackson 1983) may include unconfirmed poisonings and inquiries about toxins, with or without associated incidents. Data compiled from the records of diagnostic laboratories (Quick 1982;Blakley 1984) are based on cases investigated by chemical analysis, thereby excluding poisonings confirmed by other means or for which chemical analysis is unsuccessful or not available.…”

“…The economic magnitude and health problems associated with this rodent species emphasize the need to develop techniques for their management. Presently, the main approach used to tackle rodent problems all over the world is to reduce their population by killing them with rodenticides (Jackson 1979;Buckle 1994;Parshad 1999;Jain & Tripathi 2000). Poisons are useful for reducing high-density rodent populations (Singla & Parshad 2000), thereby immediately reducing damage.…”

Mature and healthy male house rats, Rattus rattus (n= 160) were fed on bait (cracked wheat: powdered sugar, 98:2) containing different concentrations of triptolide (0.1, 0.05, 0.025 and 0%) for 7 and 14 days in no-choice and bi-choice feeding tests in the laboratory. The objective of the study was to record the antifertility affects of triptolide after 30 and 60 days of termination of treatment. Results revealed no significant effect of triptolide treatment on weights of testis, epididymis, seminal vesicles and prostate gland of rats. Overall, sperm motility, live sperm count, sperm density and sperm morphology in the cauda epididymal fluid were found to differ significantly (P≤ 0.05) between untreated and treated groups of rats. The major effect of triptolide on sperm morphology was in the form of sperm head tail separation, which was up to 56.0% in rats treated for 14 days in no-choice and autopsied after 30 days. A significant effect (P≤ 0.05) of triptolide treatment was observed on the histomorphology of the testis, which included a dose-dependent decrease in diameter of seminiferous tubules, thickness of germinal epithelium and numbers of various spermatogenic cells. Cell associations in the seminiferous epithelial cycle were poorly developed in rats ingesting medium (4.7-5.1 mg/100 g bw) and high doses (6.9-7.2 mg/100 g bw) of triptolide than rats ingesting low doses (1.8-2.3 mg/100 g bw) and untreated rats. The cell stages affected had not recovered fully within the 60 day period following triptolide withdrawal. The present study suggests the potential of triptolide in reproductive management of Rattus rattus.

“…If not, a new method for the species should be applied concurrently with another proven (but perhaps more difficult) method, or otherwise validated on the target species before being used exclusively for making management or research inferences.

Monitoring populations of problem species is an essential component for integrated damage reduction programs. Tracking population size through time and space helps define the potential magnitude and geographical extent of damage. Population size at an early stage of a crop cycle can serve as a predictor of damage levels later on, indicating whether control is necessary or what fonns would be economically optimal. The ability to monitor for population change also permits assessment of the efficacy of the control methods for reducing numbers of a pest species. Methods for quantifying population levels can be as diverse as the number of subject species, the objectives of an IPM program, and whether direct estimates or indices of population parameters are required. Often, indirect methods involving counts of tracks, burrows, droppings, or food removal are used. We review methods used for a variety of wildlife species, examine the desirable characteristics for useful monitoring methods, and describe some of our current research on indexing methods.
