Abstract

A study was made to measure the differences among the progeny of 12 Teak clones of Madhya Pradesh, viz. C-5, 6, 8, 11, 60, 72, BBC-23, 28, 44, BSC-28, CSC-9 and KEKC-7, for damage impact and feeding potentiality of the larvae of Eutectona machaeralis (Walker), in nursery and laboratory respectively. Based on the level of larval defoliation impact and leaf consumption, response of this pest exhibited that progeny of clone CSC-9 of Chhindwada Sillewani was least preferred followed by C-11 and C-8 of Seoni Kurai, whereas most preferred clonal progeny was KEKC-7 of Khandwa East Kalibheet followed by BSC-28 of Betul Sarni. The weight gained by larvae fed on leaves of least and most preferred clonal progenies were significantly (P<0.05) reduced and greater than those of others respectively. The leaf water content of clonal progeny showed a gradual increase in relation to leaf consumption. All the parameters included in the study showed positive and significant (P<0.05-P<0.01) correlation. The findings suggest that the variation in progeny of Teak clones may play a decisive role for differential reaction of this insect pest.

Abstract

Temperature and humidity are the two main factors that influence the rate of survival, oviposition, growth and development and the fecundity of an insect. Experiments were carried out during 1996-97 to determine the effect of temperature and relative humidity on the egg, larval, pre-pupal and pupal period of Albizia foliage feeder, Spirama retorta Cram. (Lepidoptera:Noctuidae), a devastating pest of forest nurseries and young plantations in Central India. The recorded field temperature during study/survey period was 5 to 45°C and relative humidity 20 to 80% in Central India covering the state of Madhya Pradesh, Maharashtra and Orissa. Study of the effect of temperature and humidity revealed that the best suited optimum temperature and relative humidity was between 30-35°C and 60-80% which enhanced the viability of eggs and shortened the egg, larval, pre-pupal and pupal duration. Low temperature (5 - 25°C) and humidity (20 - 60%) lessened the viability of eggs and increased the mortality and the duration of various life stages. The maximum mean viability of eggs (99.00 ± 1.00) was recorded at 30°C and 80% where as the shortest egg period was 3- 4 days observed at 35°C and 40-80% relative humidity. The shortest mean period in days was also observed for larval (11.12 ± 0.3750), prepupal (1.62 ± 0.1250) and pupal (9.67 ± 0.2870) between 30 - 35¤C and 60-80%. These finding were correlated with the field temperature and humidity and found that temperature, humidity and species of food plants (quantitative and qualitative) favored this insect to occur in an epidemic condition, in forest nurseries and young plantations during monsoon season.

Abstract

For evolving an eco-friendy, non-toxic and practically feasible method of minimizing the populataion of the most serious Teak leaf skeletonizer E. machaeralis, four egg parasitoids viz. Trichogramma brsiliensis, T. chilonis, T. pretiosum and T. japonicum were tested in laboratory conditions. T. brasiliensis proved a better potential species to parasitise maximum number of eggs in labortory i.e. 58 to 61 per cent. Further evaluation of T. brasiliensis in field conditions for their least effective dose, proved that the optimum dose of the egg parasitoid T. brasiliensis is 1.25 lakhs wasps/ha to minimize the attack of teak leaf skeletnizer, E. machaeralis.

Abstract

An experiment was laid out in Sal forest at Jagatpur under Karangia Range of Mandla division during the recent epidemic of Sal heartwood borer, Hoplocerambyx spinicornis Newman, in Madhya Pradesh, with a view to find out the girth class preference of the insect in Sal trees and subsequent mortality. Results based on four years observations revealed that total per cent mortality of Sal trees due to borer attack was recorded to be 5.17% in experimental plot. The results reflect the post effect of Sal borer epidemics. The borer attack was noticed from the girth class more than 61-90cm (4.24%),91-120 cm (5.08%) and finally peak in 121-150 cm (6.78%) and then declined in girth class above 151 cm (3.12%). Further, the frequency distribution of girth class of Sal trees and tree mortality due to borer attack exhibited maximum mortality in 102-116 and 117-131cm ranges. These findings clearly advocate the girth class preference by borer beetles in Sal forests.

Abstract

Toxicity of Ivermectin (Ivecop-12)-was evaluated against the larvae of a major defoliator of Teak, Hyblaea puera Cramer, during the outbreak period (July-August) in teak (Tectona grandis L.f.) forests of central India. The study was conducted once with eight treatments of higher (lethal) concentrations and then thrice with eight treatments of lower (lethal and sub-lethal) concentrations. Results revealed that ivermectin is highly toxic which could induce larval mortality when applied on host plant leaves and larvae together of the insect pest. Toxicity of ivermectin was found to be effective at ppm level and knock-down toxicity was noticed to be very rapid. Among the concentrations of ivermectin tested, cent per cent mortality was recorded by the higher concentrations up to 1172 ppm (0.001172%) and significantly different (P<0.01) from other treatments of lower concentrations including control. Further, there was a gradual decline of larval mortality with respect of lowering concentrations of the ivermectin. The LC₅₀ value of the tested biological product was worked out to be 282 ppm (0.000282%) against the target insect pest.

Abstract

The inheritance pattern of infestation and loss in seed yield due to a potential seed borer, Bruchus bilineatopygus Pic. (Coleoptera : Bruchidae), was quantified among open pollinated seeds of ten phenotypically superior trees (plus trees) of Albizia procera (Roxb.) Benth., collected from Bilaspur District of Chhattisgarh, India. Among the seeds of superior trees, entomological screening based on the level of borer infestation and loss in seed biomass revealed seeds of 2 trees namely PT-5 and PT-7 as highly resistant (< 5%), 4 trees namely PT-1, PT-2, PT-4 and Pt-6 as resistant (> 5 - < 10%), 3 trees namely PT-3, PT-8 and PT-10 as susceptible (> 10 - <20%) and only one tree namely PT-9 as highly susceptible (> 20%). Significant variations were noticed for the parameters included in the study. Small difference between phenotypic and genotypic coefficients of variation was observed for per cent infestation and loss in seed biomass. Heritability (broad sense) and genetic gain estimates were also high for these parameters suggesting that additive gene action is more important for these traits.

Abstract

Shorea robusta, which is one of the most important timber species of India, yields about 2.5lakh m³ of timber and 3lakh m³ of firewood. A heartwood borer, Hoplocerambyx spinicornis, often damages it. Its beetles emerge soon after a few showers of monsoon rains from the third week of June to the end of August. They attract to the odour of freshly cut bast and sapwood of sal. Soon after mating, the beetle oviposit white, cream coloured eggs in cracks on the bark. After 3-7 days of egg period, the hatching takes place. The freshly hatched grubs bore the bark and reach to the sapwood, where they form tunnels. After feeding the sapwood, the grub move to heartwood where they form a wider pupal chamber, the grubs start pupation from December onwards, develop to immature beetles between April to May and emerge out from middle June onwards during monsoon. The male has long antennae than their body while the female has short antennae. The incidence of attacked sal trees due to heartwood borer lasts upto 24.33 per cent during epidemics. Continuous favourable climatic conditions, vicinity of human and herbivore population, physiological properties of sal trees to insect borer, quantitative and qualitative changes in host trees, natural enemies of sal borer and weaken of defensive system of sal trees are recorded as probable factors responsible for sal borer epidemics. Borer killed more than 26lakhs of sal trees during recent sal borer epidemics between 1996-02. Felling of these attacked sal trees in dense sal forests opened the canopy and resulted an average regeneration upto 4.18 saplings per square meter of sal and other miscellaneous species as compared to 1.95 saplings per square meter in unfilled sal areas. In human inhabitant areas however, it is reported to be comparatively low. Besides existing preventive and remedial control measures, the authors have advocated spraying of 0.05% endosulfan 3.5 ml insecticide per litre of water of 0.05 per cent chlorpyriphos (10 ml insecticide/litre) on stored borer attacked sal stacks and then covering them with polythene sheets before monsoon in June to kill the beetles emerging from sal logs. Further research need on sal heartwood borer, its out break and management are also mentioned.

Abstract

There was an epidemic of Khasi pine shoot borer,Dioryctria castanea in 1982 in Yachuli Khasi pine plantations in Arunachal Pradesh. All age groups were attacked. Two field trials were conducted at Yachuli to find out the efficacy of phosphamidon, dimethoate,monocrotophos, methyl-demeton, formothion and thiometon against the shoot borer. Spraying of 0.03% phosphamidon/0.03% dimethoate/0.04% monocrotophos/0.03% formothion/O.03% thiometon in the last week of February was highly effective in reducing the incidence of the shoot borer.

Abstract

Seismic microzonation studies in Delhi have been carried out solely on the strength of the geotechnical data available with the Geological Survey of India. The main derivative products of the exercise include the shear wave velocity and predominant frequency maps on 1,50,000 scale. These maps are based on the N value data of subsurface soil columns, mostly down to a depth of 30 m, as observed at 121 Bore-Hole sites, in addition to the depth to bedrock, and other geological and geomorphological information.

The different ground response parameters, e g shear wave velocity and predominant frequency have been estimated by using empirical relationships developed elsewhere, especially m California, USA Although the tenacity of the qualitative/ semi quantitative results is yet to be affirmed, the maps, by and large conform to the effects of the past near and far events, such as the 1905 Kangra, 1960 Delhi and 1999 Chamoli earthquakes.

The amplification of the ground motion being the inverse function of impedance contrast between the underlying hard rock and the overlying soft sediments in Delhi, where the underlying rock is represented by quartzite, practically, the relative values of shear wave velocity of the soft sediments indicate the likely amplification - the low velocity promoting higher amplification A maximum ground motion amplification of 12 5 times and a minimum of 5 times, when assuming the damping as zero, has been estimated However, the actual amplifications are bound to be less because the soil does dampen the ground motions The predominant frequency map prepared on the assumption of simplified subsurface configuration, provides a generalized picture of the range of frequencies expected to get amplified -the amplification governed by the shear wave velocity of the soil cover there.

Abstract

Signatures of active tectonics have been observed in the eastern part of Doon valley in proximity to a lineament (fault?) cutting across the Himalayan grain. A normal fault has been observed over the Doon sediments represented by a sequence of silty clay, gravel and clay exposed in a quarry section. The fault displaces the litho sequence with a vertical throw of 1 5 m. This suggests tectonic movement along the fault during Quaternary period.

Abstract

An earthquake of magnitude 5.0 with its epicenter in the West Sikkim district occurred on the evening of 20^th May 2007. The macroseismic study revealed an ENE-WSW isoseismal pattern indicating a trend conforming to that of the major tectonic discontinuities in this part of the Himalaya.

The relatively moderate event, felt even at far away places like, Siliguri, Darjeeling, etc induced a maximum intensity of VI (MSK) in the form of development of cracks in the walls, fall of thick chunks of plaster in Type A or even Type BC structures at localities like Tashiding, Ralang, Rabang, Keozing, Sakyong, etc.

The study also revealed that the NW-SE trending Tista lineament is playing an important role in the release of the tectonics strain in this region and that the rupture initiated under the influence of the northward directed tectonic stresses at an asperity formed at one of the decollements within the crust by the intersection of this tectonic discontinuity was interpreted to be responsible for this seismic event.

Abstract

Soybean has a great promise to combat malnutrition in the third world countries owing to its very high content of quality protein, which contains most of the essential amino acids except S-containing ones. A few low cost technologies for converting soybean into full fat soydal, soypaneer, soymilk have been developed at Central Institute of Agricultural Engineering. Bhopal, which are used in the preparation of a number of traditional recipes.
