Anand Agricultural University, Anand

Anand Agricultural University (AAU) was established in 2004 at Anand with the support of the Government of Gujarat, Act No.(Guj 5 of 2004) dated April 29, 2004. Caved out of the erstwhile Gujarat Agricultural University (GAU), the dream institution of Sardar Vallabhbhai Patel and Dr. K. M. Munshi, the AAU was set up to provide support to the farming community in three facets namely education, research and extension activities in Agriculture, Horticulture Engineering, product Processing and Home Science. At present there seven Colleges, seventeen Research Centers and six Extension Education Institute working in nine districts of Gujarat namely Ahmedabad, Anand, Dahod, Kheda, Panchmahal, Vadodara, Mahisagar, Botad and Chhotaudepur AAU's activities have expanded to span newer commodity sectors such as soil health card, bio-diesel, medicinal plants apart from the mandatory ones like rice, maize, tobacco, vegetable crops, fruit crops, forage crops, animal breeding, nutrition and dairy products etc. the core of AAU's operating philosophy however, continues to create the partnership between the rural people and committed academic as the basic for sustainable rural development. In pursuing its various programmes AAU's overall mission is to promote sustainable growth and economic independence in rural society. AAU aims to do this through education, research and extension education. Thus, AAU works towards the empowerment of the farmers.

    STUDIES ON CATOPSILIA PYRANTHE LINN. (LEPIDOPTERA: PIERIDAE) A PEST OF SENNA, CASSIA ANGUSTIFOLIA VAHL. IN ANAND (GUJARAT)
    (AAU, Anand, 1987) PATEL, H. M.; Yadav, D. N.
    Captopsilia pyranthe Linn. (Lepidoptera : Pieridae) has been reported as a serious defoliator of a medicinal crop, Senna, Cassia angustifolia Vahl. Studies on its biology, seasonal abundance, natural enemies and chemical control were carried out at Anand Campus of Gujarat Agricultural University during 1983-84 and 1984-85. Biological observations revealed that, the pest lays eggs singly on the foliage which hatch out in two days. It passed through five distinct larval instars to complete its development and duration of each instar was on an average 1.20, 1.12, 1.32, 1.68 and 2.83 days during June (when average minimum and maximum temperatures were 30.49 °C and 38.00 °C and relative humidity was 68.3 per cent and 1.73, 1.33, 1.60, 1.93 and 3.13 days during September and October (when average minimum amd maximum temperatures were 27.71 °C and 34.75 °C respectively and relative humidity was 59.09 per cent) respectively.

    EVALUATION OF GRAIN PROTECTANTS AGAINST Callosobruchus analis F. INFESTING GREEN GRAM Vigna radiata (L) Wilozek.
    (AAU, Anand, 1990) GEORGE, V.; Patel, J. R.
    The relative bio-efficacy of some botanical, and other materials in comparison to synthetic insect- cides against pulse beetle Callosobruchus analis F. infesting green gram Vigna radiata (L.) W, was evaluated in laboratory during 1989-90. The synthetic insecticides, malathion and fenvalerate were used @ 0.05 and 0.02 per cent respectively, while the rest of the treatments were @ 10 per cent (w/w) except corn-care, which was at 1 per cent. The seeds under control treatment was sprayed with double distilled water (10 per cent-v/w) only. Five adults of C. analis i.e. three females and two males were released to the treated green gram. The green gram stored with various botanical materials, synthetic insecticides and other grain protectants had comparatively low oviposition by pulse beetle C.analis as compared to untreated grains on the 10th day of releasing the insects.

    BIOLOGICAL STUDIES ON Euplectrus xanthocephalus Girault A NEW ECTO-LARVAL PARASITE OF Spodoptera litura ( Fab.)
    (AAU, Anand, 1983) VIRANI, VALLABH R.; YADAV, D. N.
    Biological studies on the Eulophid parasite, Euplectrus xanthocephalus Girault parasitising Spodoptera litura Fab. were made in the laboratory during 1981-82 at the Anand Campus of Gujarat Agricultural University. The studies revealed that the Euplectrus females laid their eggs in groups of 6 to 8 on the 2nd to 5th stage larvas. The eggs hatch out in 1.2 to 1.9 days and the parasite larvas start feeding the host externally, The larvae pass through 5 instars to complete their development in 4.95 to 5 days. They undergo a short prepupal stage which lasts for 2.03 days. The pupation occurs underneath the dead host larvas. The pupal stage varied from 5.06 to 6.06 days. The entire development of the parasite from egg deposition to adult emergence varied from 9.0 to 11.60 days.

    (AAU, Anand, 1982) KABARIA, BABU B.; Chari, M. S.
    To evaluate the bio-efficacy of some insecticides against insect pests of Hybrid-4 cotton, an experiment was conducted for two years during 1980-81 and 1981-82. The first trial was conducted during 1980-81 with the following treatments viz. Phenthoate-EC (Elsan, 50 EC, 1.625 l/ha), endosulfan (Thiodan, 35 EC, 1.5 l/ha), chlorpyriphos (Damisban, 20 EC, 1.25 l/ha), carbaryl (Sevin, 50 wp, 2 kg/ha), phenthoate-D (Elsan, 2% dust, 31 kg/ha), diazinon (Bazanon, 20 EC, 1 l/ha), monocrotophos (Nuvacron, 40 EC, 1.5 l/ha) and control (water spray only). Seven spraying were given at an interval of 15 days. The results on sucking insect pest complex showed that monocrotophos gave excellent protection to the crop from aphids, jassids and thrips.

    POPULATION STUDIES OF HELIOTHIS ARMIGERA (HUBNER) AND ITS INSECTICIDAL CONTROL ON BIDI TOBACCO
    (AAU, Anand, 1983) Rao, B. Sreenivasa; Chari, M. S.
    Heliothis armigera (Hb.) is a serious polyphagous pest on various crops. In bidi tobacco it is a pest on capsules and hinders the production of tobacco seeds. It is one of the limiting factors in the production of improved varieties of tobacco seeds. The population of Heliothis moth was studied during the year 1982 using pheromone and light trap of ICRISAT model. The daily observations on the moth catches were recorded everyday throughout the year. The data on the population of H. armigera were correlated with the weather parameters and moon phases. The Heliothis armigera was active through out the year except in September. The maximum catches were obtained during February-March. The activity was gradually reduced in April and reached to zero level in the month of September.

    (AAU, Anand, 1980) SORTHIA, B. K.; Chari, M. S.
    Tobacco stem borer, Scrobipalpa heliopa Low. Is an important pest of rustica, bidi and virginia tobacco grown in India. The studies on the life history of stem borer indicated that a single female moth lays on an average 78 eggs. The eggs hatch in about 5-10 days with an average of 7.21 days. The temperature of 30°C was the best for the lowest incubation period and highest percent age of hatching. The relative humidity between 60 to 70 per cent at a constant temperature of 25°, 27° and 30°C was most congenial. The average duration of the first, second, third, fourth and fifth instar was 4.23, 4.72, 5.18, 4.31 and 4.94 days respectively. The total larval duration varied from 18 to 30 days with an average of 23.33 days.

    BIONOMICS AND PROPHYLACTIC CONTROL MEASURES OF POWDER - POST BEETLE DINODERUS MINUTUS, FABRICIUS (BOSTRICHIDAE : COLEOPTERA)
    (AAU, Anand, 1980) DODIA, DILIPKUMAR A.; Patel, N. G.
    Power-post beetle (Dinoderus minutus, Fabr.) has become a serious pest of rice. The egg period in this pest species was 4.0 to 7.0 days with an average of 5.27 days. The hatching percentage was 67.33% at 32.43 ± 0.29°C. The larval period varied from 52 to 78 days with an average of 61.16 days at 27.71 ± 0.34°C. Most of the larvae moulted seven times, but some moulted eight times. The pre-pupal period was invariably only one day. The pupal period varied from 3 to 5 days with an average of 4.16 days. The egg laying capacity of the beetle varied from 3 to 13 with an average of 9.6 eggs within 24 hr. Both the larvae and the adults caused damage to the rice grain near its germ portion and rendered it useless for human consumption. Rice flour along with the frass was found to be collected at the bottom of the container in the laboratory. At times few grains were found to be adhered each other in the salivary secretion of the insect.
