Out of 373 buffaloes examined in different localities of Dehradun, 60.58% have been found infested with Haematopinus tuberculatus. Incidence of infestation was higher on adults than on youngs. The lice index was highest in January and lowest in June. The adults and nymphs preferred neck, back, ribs, shoulder, belly, thigh, hind, flank, head, hind legs,(More)
The distribution of three amblyceran (Menacanthus stramineus, Menacanthus cornutus, Menopon gallinae) and five ischnoceran species (Lipeurus lawrensis tropicalis, Lipeurus caponis. Goniocotes gallinae, Goniodes gigas, Goniodes dissimilis) on poultry was determined. The preferred sites of these species on the host body were recorded.
The order of abundance of different mallophagan species on poultry birds in Dehradun (India) has been found to be Menopon gallinae greater than Menacanthus cornutus greater than Menacanthus stramineus greater than Goniocotes gallinae greater than Goniodes dissimilis greater than Lipeurus caponis greater than Lipeurus lawrensis tropicalis greater than(More)
A study was conducted to evaluate the effect of GA3, moist-chilling and temperature on seed germination of Abies pindrow and Picea smithiana from five different provenances. Seeds were soaked in GA3 (10 mg·L−1) for 24 h, then chilled at 3–5°C for 15 days. Four temperature regimes viz. 10°C, 15°C, 20°C and 25°C were used for stimulating seed germination.(More)
We investigated the effect of provenance variation on cone and seed morphology and germination behaviour under different pretreatments in Picea smithiana. Three categories of cones were recognized: large (13.18 cm × 3.30 cm−15.42 cm × 4.35 cm), medium (10.85 cm × 3.93 cm−12.18 cm × 3.98 cm) and small (7.69 cm × 3.06−10.98 cm× 3.39 cm). Significant variation(More)
The prevalence of two phthirapteran species, Bovicola caprae and Linognathus africanus, on 1048 goats from Dehradun (India) was 79.2% and 38% respectively. Prevalence of both species was higher on visibly weaker and less hairy goats. Sex related differences in prevalence were not found. The prevalence of L. africanus was slightly higher on young goats but(More)
The population structure of Bovicola caprae on goats has been recorded by examining 57 goatskins (45 by brushing cum searching and 12 by dissolving method). Population composition, sex ratio, adult nymph ratio has been recorded at different levels of infestation. The female dominated over the male population and male: female has been found to be 1:2 by(More)
