Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014.

    BIOLOGY, PREDATORY POTENTIAL OF Cryptolaemus montrouzieri Mulsant ON PAPAYA MEALYBUG AND SAFETY EVALUATION OF CERTAIN INSECTICIDES ON PREDATOR
    (Acharya N.G. Ranga Agricultural University, 2017) MANEESHA, A; KOTESWARA RAO, S.R.
    The present studies on “Biology, Predatory potential of Cryptolaemus montrouzieri Mulsant on papaya mealybug and Safety evaluation of certain insecticides on predator’’ were carried out at Insectary, Department of Entomology, S.V. Agricultural College, Tirupati during 2016-17. Biology including morphometrics, predatory potential of C. montrouzieri on papaya mealybug, biology on different life stages of papaya mealybug and evaluation of toxicity of different insecticides on predator were studied. Studies on the biology of C. montrouzieri on Paracoccus marginatus revealed that the oviposition period, male longevity and female longevity was 43.60 ± 2.95, 70.70 ± 2.75 and 77.30 ± 5.03 days, respectively. The mean egg period, duration of I, II, III and IV instars, pre- pupa and pupa was 3.13 ± 1.12, 2.96 ± 0.65, 4.30 ± 0.57, 5.73 ± 0.75 and 6.40 ± 0.78, 2.30 ± 0.49 and 7.50 ± 0.96 days, respectively. The total grub period and developmental period i.e. from egg to adult was found to be 22.50 ± 1.33 and 32.30 ± 1.55 days, respectively. The mean fecundity of female was 272.60 and sex ratio was 1: 1. The morphometrics of the C. montrouzieri revealed that the average length and breadth of egg was 0.81 ± 0.05 mm and 0.41 ± 0.04 mm. Similarly, the average length and breadth of I, II, III and IV instar grubs was 1.26 ± 0.26 mm and 0.49 ± 0.05 mm; 4.60 ± 0.47 mm and 1.17 ± 0.08 mm; 6.06 ± 0.53 mm and 2.00 ± 0.30 mm; 8.44 ± 0.64 mm and 4.12 ± 0.15 mm, respectively. The xiv average length and breadth of pre- pupa and pupa was found to be 8.96 ± 0.36 mm and 4.30 ± 0.35 mm; 9.08 ± 0.46 and 4.32 ± 0.58 mm, respectively. The average length and breadth of adult male and adult female was 3.85 ± 0.24 mm and 2.89 ± 0.12 mm; 4.25 ± 0.28 mm and 3.20 ± 0.20 mm. The total developmental period of C. montrouzieri was significantly highest when reared on ovisacs of papaya mealybug, when compared to that of I, II and III instar nymphs of P. marginatus. Feeding potential of C. montrouzieri on different stages of papaya mealybug was studied. The mean predatory potential of I, II, III and IV instar grub on Ovisac, I, II and III instar nymphs of mealybug was 1.40 ± 0.12, 30.60 ± 0.51, 20.53 ± 0.98 and 13.46 ± 1.15; 1.68 ± 0.13, 43.52 ± 0.41, 30.40 ± 0.68 and 17.33 ± 0.88; 1.90 ± 0.14, 47.04 ± 0.84, 31.56 ± 0.51 and 20.45 ± 0.84 and 1.91 ± 0.15, 54.10 ± 0.45, 38.20 ± 0.58 and 26.32 ± 1.13. Average consumption capacity of male and female on ovisac, I, II and III instar nymphs was 2.98 ± 0.09, 57.81 ± 0.24, 41.39 ± 0.12 and 28.51 ± 0.02 and 3.05 ± 0.10, 58.19 ± 0.26, 43.00 ± 0.19 and 29.28 ± 0.08, respectively. Among safety evaluation of different insecticides on life stages of C. montrouzieri, dimethoate was found to be highly toxic whereas, flonicamid, buprofezin and neem oil were found to be non-toxic through food contamination method. In dry film method, acephate was highly toxic while, buprofezin and neem oil were least toxic to all the stages of the predator
