    Diversity and seasonal incidence of aquatic insects of ponds in South-West Punjab
    (Punjab Agricultural University, Ludhiana, 2019) Sukhpreet Kaur; Hundal, S.S.
    A comparative study was conducted dealing with diversity and seasonal incidence of aquatic insects of ponds in South-West Punjab. Aquatic insects are group of arthropods that spend some or almost full life in water. They act as bioindicators and help in determining water quality of different water bodies. The sample collection was done fortnightly from 3 villages of Faridkot district viz. Pakka, Chambeli and Bhana from June 2018 to May 2019. The insect specimens were got identified and confirmed from ZSI, Kolkata and analysis of water samples for physico-chemical parameters was done using standard methods. A total of 1103 individuals of aquatic insects belonging to 4 orders (Coleoptera, Odonata, Hemiptera, and Diptera) were collected from three village ponds. The maximum number of aquatic insects was recorded from village Pakka (373) while minimum number was recorded from village Bhana(311). Hemiptera was the most dominant order in all three village ponds. Various water quality parameters like temperature, pH, EC, DO, BOD, alkalinity etc. were analysed. It was observed that there were slight variations in water quality parameters in three ponds. The result of study indicated high diversity of aquatic entomofauna in pond of village Pakka and suggests the possibility of using aquatic insects efficiently for biomonitoring purposes.

    Bird composition in relation to management practices of orchards in Ludhiana district
    (Punjab Agricultural University, Ludhiana, 2016) Sukhpreet Kaur; Kler, Tejdeep Kaur
    The present study was carried out to observe bird composition in relation to management practices of orchards in Fruit Research Farm, Punjab Agricultural University campus, village Birmi and village Baranhara in Ludhiana District from March 2015 to February 2016. A total of 52, 44, 38, 49, 31and 30 bird species had been noted in the transects I, II, III and IV of Fruit Research Farm, PAU, transect V of orchard at village Birmi and transect VI of orchard at village Baranhara respectively. Order wise Passeriformes and feeding habits wise omnivorous were most dominant in all the said transects throughout the study period. In transect IV management practices (bird manual scaring) were performed and guava crop fruit damage was found to be estimated 5.5%. Data was taken on ber trees protected with manual scaring and netting. Bird damage was 11.08% in manual scaring area and nil on the netted trees. Guava fruit damage was estimated 42.50% and 23.50% at fruit ripening stage (without management practices) in transect V of village Birmi and transect VI of village Baranhara respectively. In the comparison of guava crop at different developmental stages, 22 species were in transect IV, 19 species in transect V and 25 bird species in transect VI were recorded. The implementation of management practices (netting, manual scaring) helped in reducing the bird damage in guava and ber crop. The present study suggested that mixed fruit orchard seemed to provide food to bird species of different tropic levels from frugivores to carnivores.
