  On-going main research programmes

1.Ecology and management of plant and strored mites of agricultural importance.

2.Ecology and management of field rodents of agricultural importance.

3.Effective utilization of some exotic species of earthworms for the production of vermicompost and its further utilization in agricultural crops.

  Major contributions in Research
  • Pollination biology and pollination requirements of alfalfa, carrot, coriander, cauliflower and many oil seed crops.
  • Foraging behaviour and Management of Apis mellifera L. in semi arid conditions.
  • Pesticidal toxicity to honeybees and identification of safe insecticides.
  • Pesticidal residues in honey and pollen.
  • Technology for keeping solitary bees for pollination of forage crops.
  • Taxonomy of stored, plant and parasitic mites associated with honeybees and vertebrates. Several new species were recorded.
  • Bio ecological and management studies on plant, stored product and honeybee mites.
  • Earthworm species Eisenia foetida is the best species for the bio-degradation of bio-waste. The vermicompost produced by this species has minimum C:N ratio and can be effectively used in agricutlrue and fish culture.
  • Methodology for the control of field rodents.
  Salient research achievements of the department

1. Foraging behaviour of honeybees

  • The following habits of three varieties of plum were studied and found twelve insect species visited the crop out of which Apis dorsataA. mellifera, A. florae, A. cerana and dipterans were main pollinators.
  • Three varieties of Aonla (Amla) viz. Chakaiya, NA-7 and NA-10 were selected to study floral biology and pollination ecology of the plant and found A. dorsata has the highest foraging rate followed by A. mellifera.

2. Pollination requirements of honeybees in crops

  • In bitter gourd, maximum fruit set ( 74.0%) was obtained in open+ hand pollination followed by open pollination (72.5%) and hand pollination (58.4%). No fruit set was observed in those plants in which insects were excluded.
  • In onion, average seedling length was highest in Bee pollination (2 frames strength) (11.99 cm). For 10 m x10 m area, nucleus hive of two frame strength of A. mellifera population is sufficient for seed setting in onion seed crop.

3. Pesticide toxicity to honeybee species..

  • Fipronil @ 300, 400g a.i/ acre in cotton caused 100 per cent mortality of all the three Apis species within one hour of application. Residual toxicity of Emamectin against A. mellifera reduced drastically after 24h of spray and reached to safer level on the second day except for the highest dose.

Acarology

1. Quantitative and qualitative losses due to stored mites

  • In pulses, S nesbitti caused significant reduction in grain weight and germination. Percent loss in germination was 22 to 23.6% in red, green, black and Bengal gram in six months. The weight loss was 2.24,3.53,1.87 and 2.75 percent in oat grains, flakes and green gram grains, flakes, respectively after 45 days observation periods.

2. Management of stored mites

  • The hatching period and life history of Tyrophagus putrescentiae duration was prolonged with the increasing light exposure .
  • Euclyptus, Mentha leaves, curcuma and garlic oil, powder and oleoresin, Ocimum and Glycyrrhiza extract significantly reduced the T.putrescentiae poplation in wheat grains.

3. Quantitative and qualitative losses due to plant mites

  • Total chlorophyll, chlorophyll-a chlorophyII-b and carotenoids decreased significantly in mite infestated leaves as compared to non infested leaves.
  • The significant per cent reductions in number of furits and average fruit weight at different inoculums of T. urticae were recorded over unifested plants..

4. Mangement of plant mites

  • Aqueous extact of Withania somnifera (2.5%) and G. glabra (7.5%) was effective in causing significant reduction in T.urticae population.
  • Beauveria bassiana caused significant reduction in T. urticae population in cucumber plants and increased yield over control.

5. Management of honeybee mites

  • Use of screen floor, powdered sugur (3g/frame), Formic acid 85% (5ml) provided 90.8, 97.7 and 85.3% reduction in V.destructor population over other methods.

Vermiculture

1. Breeding effecacy of earthworms

  • The effect of seasonal variation on growth & reduction was observed on different species of earthworms viz. Eisenia fetida. Perionyx excavates and Eudrilus eugeniae. It was found that in rainy season was better for cocoon production.

2. Antioxidant activities against microbes

  • The antioxidant activities were found to be in following order in earthworm species i.e. E. fetida shows maximum followed by Eudrilus eugeniae, Peionyx excavatus and Pheretima posthuma.

3. Heavy metal toxicology 

  • The earthworms (Eisenia fetida) exposed to the heavy metals, leads (Pb) and cadmium (Cd), showed toxic effects. Pb in combination with Cd, enhanced the toxic effect significantly, hereby producing a synergistic effect, the toxicity of Cd in combination with Pb (0.06 ppm) depicted a maximum reduction in carbohydrate, lipid and protein content of earth worm..
  •  

4. Relative effect of Vermicompost and Urea

  • Vermicompost (50%) + Urea (50% of the recommended dose) gave the best results in chilli, brinjal and tomato in terms of total fruit yield & other growth parameters of vegetable crops.

Rodentology

1. Field rodents identification

  • Tatera indica was found to be predominant species in bottle gourd, potato fields.

2. Field rodents management throgh rodenticides

  • For rodent management, the combination of rodenticide treatments like Bormodialone (Br) - Bromodialone (0.005%) was best over Bromodialone - Zinc Phosphide (Zn3P2) (2%) followed by Zinc phosphide - Bromodialone.
  Extension Activities

i)  Department participate every year in"Kisan Mela" and shows the latest technologies in vermiculture; vertebrate and invertebrate pest management practices, to the farmers as well as scientists/extension workers and the women farmers at the kisan mela..

ii)  Department organized the training on vermicimposting different villages in the State.

iii) Guiding number of farmers on phones on various aspects of vermiculture at Farmer's Helpline Centre (Agriculture Technology Information Centre), Directorate of Extension Education, CCSHAU, Hisar.

iv) DeliveriNg no. of extension lectures on vermicompost and rodent pest management at various Insititute/departments/University.
