Choice Tests

Both sexes of rodent pests such as Bandicota bengalensis, Millardia meltada, Mus booduga, and Rattus rattus were subjected to toxicity tests (acute rodenticide: 1.5% and 2% zinc phosphide and chronic rodenticide: bromadiolone (0.005%), under no-choice and choice tests) by using their preferred germinated cereals, namely, paddy, pearl millet, and finger millet, as bait base, individually. The results indicated that the poison baits in the germinated cereals induced all the chosen four species of rodent pests to consume greater quantities of bait perhaps due to the bait carrier’s palatability and texture. Besides these, the chosen three germinated cereals proved themselves that they are also capable of acting as suitable bait base for both selected rodenticides in bringing maximum mortality among the tested rodent pests under both no-choice and choice tests. Therefore, these germinated cereals may be recommended as a bait carrier for both zinc phosphide (2%) and bromadiolone (0.005%) poisons for the control of all these four species of rodent pests under field conditions. However, this requires field based trials with rodenticides for making a final recommendation.

SummaryThe properties of pyriminyl (N-3-pyridylmethyl-N′-p-nitrophenyl urea) as a rodenticide against the lesser bandicoot rat (Bandicota bengalensis) in Rangoon, Burma, were investigated in the laboratory. The acute LD 50 and LD 95 dose of orally administered pyriminyl for B. bengalensis were found to be 6·7 mg/kg and 23·0, mg/kg of body weight respectively. When caged bandicoots were given a choice between plain and poisoned baits, the optimum rodenticidal concentration in the bait was found to be 0·25–0·5%. Symptoms of pyriminyl poisoning appear from 1 to 4 h after feeding starts, giving individual animals time to consume from 2 to over 30 LD 50 doses of 0·5% pyriminyl before feeding stops. Deaths occurred from 4 to 96 h after either oral dosing or free-choice feeding. There appeared to be no significant aversion to the poison at 0·25% or 0·5% concentration in foods. The potential hazards and use of pyriminyl as a field bait against populations of B. bengalensis are discussed.

A study has been made of seasonal changes in the body weights of males and females, and of ovarian and uterine weights, in the Indian mole rat, Bandicota bengalensis, between July 1976 and June 1978, from areas surrounding Ludhiana (30�56'N.,75�52'E.). An attempt has been made to correlate them and peaks in reproductive activity with environmental factors such as daylength, temperature, rainfall and availability of food. During both years of study, the percentage of males was 45.2. The body, ovary and uterus were lighter during winter, and then gained weight, with peaks during April and August-September. Males were generally heavier than females. On the whole, 34.7% of females were either pregnant or lactating. The breeding season extended from mid-February to mid-October. Two peaks in breeding activity (April and August-September), with a decline during June, were separated by a period of reproductive inactivity from November to mid-February. The average litter size was 8.88 (range 5-13). Embryos occurred with almost the same frequency in the left and right uterine horns. The pre-implantation mortality was 9.6% and post-implantation mortality 4.8%; thus the total prenatal mortality was 13.7%. The percentage of embryos found resorbing was 4.1. The results have been discussed in the light of the literature on the reproductive biology of rodents in this region.

SUMMARYThe toxicity and efficacy of the acute rodenticide scilliroside was evaluated in the laboratory against the lesser bandicoot rat, Bandicota bengalensis. The acute oral LD50 and LD 95 doses for males were 0·8 mg/kg and 2·5 mg/kg respectively, and for females were 0·5 mg/kg and 1·6 mg/kg, respectively. When caged bandicoots were given a choice between plain and poison baits, the optimum concentration of scilliroside was found to be 0·05%. Symptoms of poisoning appear from 22 to 34 min after feeding starts and the latency pattern indicated an abrupt ceasing to feed at these points. Death occurred from 2 h to as long as 6 days after poisoning, following prolonged convulsive seizures. There appears to be aversion to scilliroside at all concentrations in food baits. Maximum mortality attained on free-choice feeding on scilliroside was 90%. Despite these disadvantages, the material may have merit as an alternative rodenticide to zinc phosphide where acute toxicants are to be used.
