    It was indicative from the studies that aphid, Lipaphis erysimi Kalt. was commenced from second week of January and persisted till first week of March and attained its peak (79.08 aphids/3 leaves) during 3rd week of February (7th SMW). The population of diamondback moth, Plutella xylostella L. was initiated from third week of January and persisted till first week of March and attained its peak (8.34 larvae/3 leaves) during 3rd week of February (7th SMW). Head borer, Helicoverpa armigera Hub. was noticed from first week of January and persisted till fourth week of February. It reached its peak (2.23 larvae/3 leaves) during 1st week of February (5th SMW). The population of leaf eating caterpillar, Spodoptera litura Fab. was noticed from first week of January and persisted till fifth week of February and its peak (2.09 larvae/3 leaves) was observed during 1st week of February (5th SMW). The occurrence of coccinellid beetle was started from third week of January to first week of March reached its peak (0.87 beetle/3 leaves) during 3rd week of February (7th SMW). The syrphid fly population was noticed from fourth week of January to first week of March and present throughout the season. It was at its peak (0.73 maggot/3 leaves) during 4th week of February (8th SMW).

    (DEPARTMENT OF AGRICULTURAL ENTOMOLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2021) Prabakaran V; Dr. R. K. Thumar
    Investigations on “population dynamics of sucking pests and management of red spider mite, Tetranychus urticae Koch infesting Dodi, Leptadenia reticulata (Retzius) Wight and Aruott” were carried out at Medicinal & Aromatic Plant Research Station, Anand Agricultural University, Anand (Gujarat) during 2020. Eight biopesticides viz., neem seed kernal extract (NSKE) 5 per cent, neem oil 0.3 per cent, ashwagandha 7.5 per cent, desi cow urine 5 per cent, azadirachtin 0.15 EC, Beauveria bassiana 5% WP, Metarhizium anisopliae 1.15% WP, Neemastra 100 per cent and eight acaricides viz., chlorfenapyr 10 EC, propargite 57 EC, ethion 50 SC, sulphur 80 WDG, spiromesifen 22.9 SC, etoxazole 10 SC, dimethoate 30 EC, and abamectin 1.9 EC were assessed.

    FITNESS COSTS OF Bt RESISTANCE IN Helicoverpa armigera (Hübner): IMPLICATION FOR REFUGEE STRATEGY IN Bt COTTON
    (DEPARTMENT OF AGRICULTURAL ENTOMOLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2021) S. Thangavel; Dr. C. K. Borad
    The present investigations on fitness costs of Bt resistance in Helicoverpa armigera (Hübner) in Bt cotton was carried out at the laboratory of AINPVPM: Agricultural Ornithology, Anand Agricultural University, Anand, Gujarat during 2018-2020. The Bt cotton fields of the Karjan region of the Vadodara district of Gujarat were visited frequently to collect the H. armigera larva. The survey was conducted to collect the population of Bt resistance H. armigera larvae from 105 cotton fields at weekly intervals during the year 2019-2020. During the survey total of 71 Bt resistance, H. armigera larvae were collected along with different plant parts (tender leaves, older leaves, squares, flowers, and bolls) on which they feeding and the maximum population of H. armigera larvae were collected from bolls (60.56%) and followed by tender leaves (16.90%), squares (14.08%), flowers (5.63%), and older leaves (2.82%) and other insect fauna includes five species of Lepidoptera, four species of Hemiptera and one species of Thysanoptera, Coleoptera and Orthoptera and insects predators were also recorded, which includes two species of Coleoptera and one species of Neuroptera, Hemiptera, Mantodea and Arenae (non-insect predator) were also recorded.

    (DEPARTMENT OF AGRICULTURAL ENTOMOLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2021) Patel Khushbuben Nareshbhai; Dr. R. K. Thumar
    Studies on “Evaluation of insecticides on aphids infesting coriander” was carried out at Agronomy Farm, BACA, Anand Agricultural University, Anand (Gujarat) during 2019-20. Nine different biopesticides viz., neem seed kernel extract (NSKE) 5 per cent, neem oil 1 per cent, kalmegh extract 10 per cent, garlic bulb extract (GBE) 5 per cent, ginger rhizome extract (GRE) 5 per cent, tobacco decoction 2 per cent, indranama fruit extract 5 per cent, cow urine 2 per cent, asfoetida + ajawain + turmeric 2 per cent and nine insecticides viz., , tolphennpyrad 15 EC, afidopyropen 5 DC, thiamethoxam 25 WG, pymetrozine 50 WG, dinetofuran 20 SG, flonicamid 50 WG, dimethoate 30 EC, flupyradifurone 200 SL and sulfoxaflor 21.8 SC were evaluated.

    ORIENTATION RESPONSE OF Helicoverpa armigera (Hübner) TO DIFFERENT HOST PLANT VOLATILES
    (DEPARTMENT OF AGRICULTURAL ENTOMOLOGY B. A. COLLEGE OF AGRICULTURE ANAND AGRICULTURAL UNIVERSITY ANAND, 2021) Shivam R. Padaliya; Dr. C. K. Borad
    Investigations on “Orientation response of Helicoverpa armigera (Hübner) to different host plant volatiles” were carried out at Anand Agricultural University, Anand (Gujarat) during 2020-21. The orientation response of H. armigera adults to volatiles of different host plants (marigold, tomato, chickpea and pigeonpea) was carried out using four-choice olfactometer. The highest attraction of both female and male moth of H. armigera was recorded towards marigold plant volatiles; it was 35.01 per cent for uncut twig and 42.32 per cent for cut twig in case of female moth as well as 36.72 per cent for uncut twig and 39.18 per cent for cut twig in case of male moth. The next higher response was observed to tomato plant volatiles. The GC-MS analysis was done to identification of host plant volatiles. Total eleven, ten, seventeen and ten plant volatiles were identified from marigold, tomato, pigeonpea and chickpea plant, respectively.
