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.

    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.

    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.

    EFFECT OF METHOPRENE ON THE GROWTH OF CIGARETTE BEETLE, LASIODERMA SERRICORNE FABRICIUS (ANOBIIDAE : COLEOPTERA)
    (AAU, Anand, 1984) PATEL, VIRENDRA G.; Chari, M. S.
    The biological effect of methoprene (IGR) on the growth and development of cigarette beetle, Lasioderma serricorne, Fabricius was made during 1982-83 and 1983-84 at Bidi Tobacco Research Station of Gujarat Agricultural University, Anand Campus, Anand. Cigarette beetle is a serious pest of stored tobacco and its products. The average larval duration of cigarette beetle in methoprene treated food was 35.52, 36.33, 38.42, 46.52, 51.23 and 31.57 days at 8, 10, 12, 13 and 15 ppm including control. Pupal duration was not affected in treated and untreated food. At all the concentrations of methoprene the adults developed into deformed beetles and failed to reproduce further and generation came to an end.

    EFFICACY OF SOME SYSTEMIC GRANULAR INSECTICIDES IN CONTROLLING YELLOW RICE BORER, TRYPORYZA INCERTULAS (WLK.) AND RICE LEAF ROLLER, CNAPHALOCROCIS MEDINALIS (GN.) AND THEIR EFFECTS ON PADDY CROP
    (AAU, Anand, 1986) Jyani, D. B.; Patel, R. C.
    The experiments were conducted in three cropping seasons during 1982 and 1983 for testing the efficacy of some systematic granular insecticides in controlling yellow rice borer, Tryporyza incertulas (Wlk.) and rice leaf roller, Cnaphalocrocis medinalis (Cn.) and the effects of these insecticides on the paddy crop. The treatments tried in experiment were carbofuran (@0.5 kg a.I./ha), carbofuran (@ 1.0 kg a.I./ha), phorate (@ 0.5 kg a.I./ha), phorate (@ 1.0 kg a.I./ha), endosulfan (@ 0.5 kg a.1./ha) endosulfan (@1.0 kg a.1./ha), Sevidol(@ 0.5 kg a.I./ha), Sevidol (@1.0 kg a.I./ha), quinalphos (@ 1.0 kg a.I./ha) and control (no insecticide). Granules were applied in 1 to 3 cm deep standing water at 25 and 50 days after transplanting. Among the insecticidal treatments carbofuran 1.0 kg a.I./ha was the best and significantly superior to all other insecticidal treatments for the control of yellow rice borer. This treatment was also the most effective treatment against rice leaf roller.

    SOME STUDIES ON PREDATORY SPIDERS IN HYBRID COTTON-6 AT ANAND
    (AAU, Anand, 1988) DHULIA, F. K.; YADAV, D. N.
    Studies were made on various predatory spiders associated with insect pests of hybrid cotton-6 at Anand Campus of the Gujarat Agricultural University during 1986-87. In all thirteen species of predatory spiders belonging to nine different families were recorded. These included five species of hunting spiders viz., Oxyopes ratnae, Glubiona sp., Castianeira sp., Plexippus sp. and Hippasa sp., four species of web-building spiders viz., Neoscona theisl, Neoscona sp.,. Uloborus khasiensis and Argiope pulchella, three species of ambushing spiders viz., Thomisus sp., T. cherapunjeus and T. projectus and one species of Olios sp. Hunting spiders dominated over other species and accounted for 63.15 per cent of the total population. Amongst these O. ratnae was found to be most important and predominant. Seasonal activity of O.ratnae, Glubiona sp., A. pulchella, Castianeira sp.. Olios sp., N, theisi, Thomisus sp. and U. khasiensis was also studied and were found predatory on insect pests such as Heliothis armigera Hxibner,, Spodoptera litura Fab., Anomis flava F., Earias vittella F., Dysdercus cinqulatus Fb., Aphis qos sypii Glover,, Ainrasca biguttula biguttula Ishida, and Bemisia tabaci Gennadius, Observations on biology of O. ratnae show that, the spider laid on an average 2.8 egg-raasses during her life span. The incubation period was 9-11 days (the average being 10.1 days) and numbers of spiderlings emerged per egg-mass varied from 30-42, with an average of 35.6. Male and female pass through 10 and 11 instars respectively to reach maturity. Male spiderlings took 157-215 days (the average being 187.20 days) whereas the female took 221-295 days (the average being 259.50 days) to complete the development. Total life span from the emergence of the spiderlings to the death of the adult varied from 260-349 days in case of male (The average being 305.8 days) whereas it varied from 323-418 days in case of female (The average being 358.80 days). The male and female mated readily under laboratory conditions, the mating lasted for few seconds. Mortality during different instars varied from 4,00 to 17.64 per cent, it was more in the 12 instar spiderlings (17.64%), The female spins silken cocoon before laying eggs and then covers them with silken threads. It was also found to take care of the eggs by sitting over them. Just hatched spiderlings were able to survive for 9.6 days when starved. The residual toxicity of fenvalerate (0.015%), endosulfan (0.07%), phosphamidon (0.03%) and monocrotophos (0.04%) was found to be high to the second instar spiderlings of 0. ratnae. Amongst them endosulfan was found having greater residual toxicity. Thus, fairly rich fauna of predatory spiders occurred in hybrid cotton-6. In view of their abundance, longer activity, long longevity and predation on variety of insects, it is suggested that as far as possible the spiders should be conserved by minimizing the apolication of pesticides such as fenvalerate, endosulfan, phosphamidon and monocrotophos. It would also be worthwhile attempting mass rearing of species like Oxyopec ratnae and Clubiona and utilizing them against insect pests of cotton. It would be interesting to study their occurrence on other crops, to know wheather these species show some affinity for particular habitat.

    (AAU, Anand, 1986) PATHAK, SUNIL KUMAR; YADAV, D. N.
    Studies on biology seasonal occurrence and mass rearing technique of Eublemma scitula Ramb. (Lepidoptera: Noctuidae) an important predator of Saissetia coffeae Wlk. (Homptera : Coccidae) infesting parwal, Trichosanthes dioica Roxb. were carried out at Anand Campus of Gujarat Agricultural University during 1985 and 1986. Biological observations revealed the E. scitula Ramb. lays eggs singly which hatches out 4-6 days. The larvae are predatory on brown scales, Saissetia coffeae Wlk. and complete their development after passing through three larval instars. The duration of first, second and third instar at 26.67 + 1.11 °C and 63.45 percent relative humidity 4.1, 4.4 and 11.7 days respectively, whereas at room temperatures during winter (average minimum, maximum temperatures and relative humidity being 20.9°C, 23.94°C and 58.90 percent respectively) and summer (average minimum, maximum, temperatures and relative humidity being 26.37°C, 29.83°C and 64.06 percent respectively), the durations were 4.5, 4.7, 11.8 and 3.2, 3.3, 9.1 days respectively.
