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. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    TRITROPHIC INTERACTIONS OF CASTOR SEMILOOPER, Achaea janata L AND ITS ENDOLARVAL PARASITOID Snellenius maculipennis (Szepligate)
    (Acharya N.G. Ranga Agricultural University, 2017) ESWAR NAIK, M; HARIPRASAD, K.V.
    Laboratory studies on the “Tri-trophic interactions of castor semilooper, Achaea janata L and its endolarval parasitoid Snellenius maculipennis (Szepligate)” were carried out during 2016-17 at Insectary, Department of Entomology, S. V. Agricultural College, Tirupati. Six varieties of castor viz., DPC-9 (Green zero bloom), DCH-177 (Red single bloom), PCH-111 (Green double bloom), 48-1 (Red double bloom), DCH-519 (Green triple bloom) and GCH-4 (Red triple bloom) were grown in plastic pots during kharif 2016 from August onwards under net house conditions. Excised leaves of equal maturity castor varieties with different blooms were used for studying the biology of A. janata at 28 ± 2˚C temperature and 75-80 per cent RH. Longest larval duration, adult longevity, total life cycle with more larval weights and fecundity of A. janata were observed when reared on DPC-9 (14.42 ±0.87 days; 13.15±0.93 days; 40.77 ± 01.52 days and 1.253 ± 0.129 g; 316.5 ± 20.07 eggs, respectively), indicating DPC-9 as the most preferred variety for growth and multiplication of A. janata followed by DCH-177 (14.25 ±0.81 days; 13.00 ±0.72 days; 40.70 ±01.17 days and 1.202 ± 0.090 g; 276.5 ± 35.19 eggs, respectively). The Shortest larval duration, adult longevity, total life cycle with less larval weight and fecundity of A. janata were observed when reared on GCH-4 (12.42 ±0.81 days; 12.75 ±0.73 days; 36.47 ±03.21 days and 0.925 ± 0.218 g; 234.25 ± 20.27 eggs, respectively) followed by DCH-519 (12.50 ±0.58 days; 12.65 ±0.58 days; 37.15 ±01.25 days and 1.191 ± 0.095 g; 231.0 ± 13.16 eggs, respectively), recording as least preferred hosts for growth and multiplication of A. janata. The performance of A. janata on the remaining varieties were in between DPC-9 and GCH-4. Approximate digestibility (AD) of third instar was highest when reared on GCH-4 (0.953±0.003 mg) and lowest when reared on DCH-177 (0.469±0.191 mg). Efficiency of conversion of ingested food (ECI) of fourth instar was highest when reared on DPC-9 (0.840±0.190 mg) and lowest ECI were observed when reared on GCH-4 (0.521±0.152 mg). Efficiency of conversion of digested food (ECD) and consumption index (CI) of fifth instar was highest when reared on DPC-9 (0.675±0.132 mg; 0.914±0.009 mg) and lowest efficiency of conversion of digested food (ECD) and consumption index (CI) were observed when reared on GCH-4 (0.379±0.050 mg; 0.219±0.045 mg, respectively). Protein content, total free amino acids, total carbohydrates and reducing sugars were positively correlated with total larval duration, adult longevity, total life cycle and fecundity of A. janata (statistically not significant). Total phenols content was negatively correlated with total larval duration, adult longevity, total life cycle and fecundity of A. janata. (statistically significant). Per cent parasitization by S. maculipennis on A. janata larvae released on castor varieties with different blooms was higher on PCH-111 (67.5±7.73 %) followed by DCH-177 (63.3±31.97 %), 48-1 (61.2±10.38 %), DCH-519 (61.2±10.30 %), GCH-4 (60.4±12.50 %) and DPC-9 (50.7±15.32 %) (Not statistically significant). Biological parameters of parasitoid, S. maculipennis such as egg+larval duration, cocoon duration, adult longevity and total life cycle, when larvae released on different castor varieties at different blooms viz., DPC-9, DCH-177, PCH-111, 48-1, DCH-519 and GCH-4 were 5.25 to 5.75, 4.50 to 4.75, 3.50 to 3.75, 13.2 to 13.75 days, respectively.
