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.

    “STUDIES ON BIOLOGICAL CONTROL OF FALL ARMYWORM Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) IN MAIZE”

    The present research was carried out at NIPHM, Rajendranagar, Hyderabad during the period 2020-21 on “Studies on biological control of fall armyworm Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) in maize”. The laboratory work was conducted at Center for Biological Control, NIPHM, Hyderabad to evaluate parasitation efficiency of egg parasitoids on FAW egg masses. Telenomus remus, Trichogramma chilonis, Trichogramma pretiosum and Trichogramma japonicum were subjected to parasitization on FAW egg mass as no-choice test. The parasitoid-host ratio was adjusted accordingly to 1: 10 (parasitoid adult: host eggs) to get effective parasitism. Among all egg parasitoids used, the per cent parasitization and per cent adult emergence was recorded the highest in T. remus with 87.17% and 91.36%, respectively. Among the sex ratio of all parasitoids emerged from parasitized FAW eggs, T. remus was recorded with the highest female recovery of 64%. It was noticed that T. remus was potential to parasitize more than one-layer of eggs in FAW egg mass uniformly. Whereas, Trichogramma spp. able to parasitize eggs in the outer most layer of egg mass. The field experiment was conducted during kharif 2020-21 at NIPHM, Hyderabad on maize crop for management of S. frugiperda using EPF (Beauveria bassiana and Metarhizium anisopliae) and EPN (Heterorhabditis indica and Steinernema carpocapsae) formulations as individual treatments and scheduled treatments (sprayed with EPF as first spray followed by EPN as second spray). Cumulative data obtained from this field study revealed that H. indica was found to be effective with the highest per cent reduction in larval population (84.32%) followed by S. carpocapsae (75.16%), M. anisopliae fb H. indica xiv (72.73%) and M. anisopliae fb S. carpocapsae (62.27%) treatments which were on par with each other. Among all the treatments, cumulative per cent larval reduction over control for two sprays recorded the lowest in B. bassiana (36.51%) treatment followed by M. anisopliae (51.15%) treatment. Whereas, the treatments imposed with B. bassiana and M. anisopliae individually during the first spray and followed by EPN during second spray recorded per cent larval reduction of 60.71-64.88% and 67.27-72.73%, respectively. The descending order of biopesticides efficacy against FAW damage (in terms of leaf damage severity rating) indicated as H. indica (1.84) > S. carpocapsae (2.10) > M. anisopliae fb H. indica (2.87) > M. anisopliae fb S. carpocapsae (2.94) > B. bassiana fb H. indica (2.99) > B. bassiana fb S. carpocapsae (3.07) > M. anisopliae (3.30) > B. bassiana (3.45). The descending order of biopesticide efficacy against FAW damage (in terms of cob damage severity rating) indicated as H. indica (1.10) > S. carpocapsae (1.17) > M. anisopliae fb H. indica (1.20) > B. bassiana fb H. indica (1.23) > M. anisopliae fb S. carpocapsae (1.33) > B. bassiana fb S. carpocapsae (1.37) > M. anisopliae (2.03) > B. bassiana (2.17). The H. indica treatment was found to be the effective by recording the highest per cent reduction in leaf damage of 38.29% and with the lowest severity rating for leaf damage (1.84) and cob damage (1.10). Among all the treatments, the highest yield was recorded with H. indica (3560 kg ha-1) accounting 87.36 per cent increase in yield over control. The ICBR (Incremental Cost-Benefit Ratio) was recorded with the highest benefit in M. anisopliae fb H. indica (1: 5.90) and H. indica (1: 5.82) treatments. Over the all parameters considered, H. indica was found to be effective and the next best treatment was M. anisopliae fb H. indica for the management of S. frugiperda
