The species diversity of parasitoids of the serpentine leaf miner, Liriomyza trifolii (Burgess) in tomato ecosystem was conducted under mid hill conditions of Himachal Pradesh during 2008–2010. The tomato leaves were collected periodically from June to September from three strata i.e. bottom, middle and top portion of the plants at random. During the course of study four species of larval parasitoids viz., Neochrysocharis formosa (Westwood), Diglyphus sp., Asecodes sp. and Chrysocharis sp. belonging to the family Eulophidae and one species of larval-pupal parasitoid, Opius sp. belonging to the family Braconidae were identified. These parasitoids were active throughout the cropping season and the parasitization ranged from 6.0 - 21.1, 19.4 - 28.6 and 13.6 - 23.1 per cent during 2008, 2009 and 2010, respectively. It was maximum (20.1 - 28.6%) during the month of August. Marginally higher parasitization (14.3 - 26.7%) was observed in the middle stratum of the foliage than in top (11.1 - 24.0%) or bottom (6.7 - 20.0%) stratum during all the three years of study. Among the larval parasitoids, N. formosa was the predominant species (81.5%), whereas, other parasitoids such as Diglyphus sp., Chrysocharis sp. and Asecodes sp. comprised of 7.4, 7.4 and 3.7 per cent of the total population of the larval parasitoids.Keywords

Apple stem borer, Aeolesthes sp. is a serious pest in apple orchards in Himachal Pradesh. For its suppression, microbial biopesticides viz., Beauveria bassiana, Beauveria brongniarti, Metarhizium anisopliae (5 x 107 conidia/gallery), Steinernema feltiae, Heterorhabditis bacteriophora (5000 infective juveniles (IJ)/ live gallery) and econeem plus (having 1% azadirachtin @ 0.5%) were evaluated. The experiment was conducted for two years during 2007-08 and 2008-09 at Temperate Horticulture Research station, Kotkhai, District Shimla. These biopesticides were compared with the recommended insecticides,dichlorvos (0.1%) and chlorpyriphos (0.04%) and control (emulsified water, 0.02%). Before applying the treatments, all the holes except one present in each branch were plugged with mud paste.The leftover hole was then cleared with the help of flexible aluminium wire and the treatment was given with the help of syringe. Thereafter, the leftover hole was also plugged with mud paste.To calculate percent mortality, the larvae which opened any of the holes in the branch or made new hole to push out the excreta were considered as live and those which remained closed throughout as dead. In this experiment, B. bassiana, B. brongniartii, M. anisopliae, H. bacteriophora, S. feltiae, econeem, chlorpyriphos, dichlorvos and control resulted in 33.3, 66.7, 37.5, 80, 20, 100, 100, 100 and 40 percent mortality during 2007-08 and 33.3, 33.3, 66.7, 33.3, 33.3, 66.7, 100, 100 and 0.00 per cent mortality during 2008-09 respectively. Among different biopesticides, M. anisopliae, B. brongniartii and cconeem plus were the best treatments resulting in 66.7 and 100 per cent mortality of stem borer larvae.Keywords

Life table studies on Eupeodes corollae (Fabricius), an important syrphid predator of the cabbage aphid, Brevicoryne brassicae (Linnaeus) in the mid-hill region of Himachal Pradesh revealed that the net reproductive rate (Ro) of the species was 187.52 female eggs/female. The true intrinsic rate of natural increase (rm) was 0.134. The population multiplied 1.14 times per day during the generation and was able to multiply 2.55 times every week. On reaching a stable age-distribution, the population comprised approximately 97 per cent of immature stages.Keywords

Studies conducted on the natural enemies of Pieris brassicae (Linnaeus) in the mid-hill region of Himachal Pradesh, revealed that mortality caused by hymenopteran parasitoids, Cotesia glomeratus (Linnaeus) and Hypersota ebeninus Gravenhorst ranged between 3.9-23.6% with its peak during mid April, while the mortality due to bacterial pathogens viz., Bacillus sp. and Serratia marcescens Bizio varied between 1.2-23.7%. Predators like Episyrphus balteatus (de Geer), Coccinella septempunctata Linnaeus and Polistes hebreus (Fabricius) though active, their role in suppressing the population of P. brassicac was negligible. The role of meteorological factors in the dynamics of natural enemies is also discussed.Keywords

Syrphids have been recognised as important predators of aphids (Ghorpade, 1981; Agarwala et al., 1984). In the mid-hill regions of Himachal Pradesh Eupeodes frequens Matsmura has been found to predate upon Brevicoryne brassicae (L.) (Aphididae, Homoptera) infesting cauliflower. The present study was undertaken to study the life-table and intrinsic rate of increase of E.frequens under laboratory conditions to understand the dynamics of this predator as biological agent of the aphid.Full Text

Mechanism of host plant resistance in tomato varieties was evaluated and compared against tomato fruit borer, Helicoverpa armigera (Hubner) attack in the Solan district known to be 'Tomato bowl of Himachal Pradesh'. Eight varieties utilized for the experiment included three self pollinating indeterminate varieties developed by selection (Solan Lalima, Solan Vajar, Palam Pink) and four hybrids (Naveen 2000+, Heem Sohna, Red Gold, Rakshita Yash Tomato). In order to locate the sources for resistance in tomato foliage various macro and micro- nutrients were extracted from these varieties and chemical composition of tomato fruits viz., content of total phenols, titrable acidity, reducing sugars and total sugars were also estimated to compare for varying levels of resistance to Helicoverpa armigera. The content of phenol and sugars in tomato fruits was found to be negatively correlated with fruit infestation with values of correlation coefficient (r = - 0.895) and (r = - 0.650), respectively, indicating that susceptible varieties were low in phenols as well as in sugars. Nitrogen (r = 0.660), potassium (r = 0.679), magnesium (r = 0.698), iron (r = 0.547) and manganese (r = 0.546) content were found to be optimistically correlated with per cent fruit infestation while, phosphorous (r = - 0.857) and zinc (r = - 0.801) content did not favor the fruit borer attack. This observed resistance can be exploited for developing crop cultivars, which readily produce the inducible response upon mild infestation, and can act as important components of integrated pest management compatible with other approaches like biological control, cultural control as well as chemical control.Keywords
