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.Keywords

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.- Girth Class of Sal Trees Prone to the Attack of Heartwood Borer, Hoplocerambyx spinicornis Newman (Coleoptera: Cerambycidae)

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.- Spermophagous Sp. (Coleoptera: Bruchidae) - a New Record of Seed Pest in Sesbania sesban (L.) Merrill

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.Keywords

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.- Sal Heartwood Borer in Madhya Pradesh

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.- Chrysoperla carnea (Stephens) : a New Record of Insect Predator on Teak Pests, Hyblaea puera Cramer and Eutectona machaeralis (Walker)

Indian Forester, Vol 138, No 2 (2012), Pagination: 123-130Abstract
Teak (Tectona grandis) is subjected to serious depredation by insect pests in nurseries, plantations and natural forests. A good number of pest resistant genotypes of teak have been identified but are not operationally deployed. Host resistance provides a highly practical eco-friendly approach of insect bio-control, as a long term solution of the problem. The cause of resistance in teak could be the result of escape from insect attack due to difference in flushing time, which in turn may have been caused by chemical, environmental or genetic factors. The present review has contemplated these aspects and elucidates research and development on clonal resistance in teak to its most pernicious insect pests, Hyblaea puera Cramer (Lepidoptera : Hyblaeidae), commonly known as teak defoliator and Eutectona machaeralis (Walker) (Lepidoptera : Pyralidae), teak leaf skeletonizer. It has also highlighted breeding for insect resistance in teak and role of biotechnology in development of resistance.Keywords

The present paper deals with research accomplishments on natural resistance in teak clones against its prime insect pest, E. machaeralis Walker (Lepidoptera : Pyralidae). It succinctly describes the importance of this insect pest, modern concept of host resistance mechanisms and necessity for identification of resistant genotypes in practical utilization. Much emphasis has been given on evaluation of resistant teak clones against leaf skeletonizer and the factors responsible for natural resistance in teak clones have been highlighted. Use of resistant teak clones may offer a viable long term solution to the leaf skeletonizer menace.- Efficacy of Three Varietal Toxins of Bacillus thuringiensis Against Ailanthus Defoliator, Atteva fabriciella Swed.

Effectiveness of three varietal toxins of Bacillus thuringiensis viz. var. dendrolimus endotoxin, var. thuringiensis and its exotoxin and var .kurslaki endotoxin. Were evaluated in the laboratory against the last instar larvae of Atteua fabriciella Swed. By spraying on larvae and food plant, Alianthus excelsa Roxb. Results revealed that the spraying of B.t. on host plant was more effective in killing larvae than on the target pest, irrespective of toxines. Among the tested toxins, var. dendrolimus endotoxin proved to be highly effective and appeared to be best, both for larval and leaf treatment @ 2.0 and 1.5% respectively.- A New Record of Perciana flavifusa Hampson (Lepidoptera: Noctuidae) on Grewia optiva Drumm. ex Burret and Growth and Development of Serious Defoliator

Tropical tasar silk, a major components of wild silks, popularized in India as "Vanya Silk", is one of the most important NTFPs that produced in nature by caterpillars of a sericigenous insect, Antheraea mylitta Drury (Lepidoptera: Saturniidae). It is commercially exploited for wild silk production in India by aboriginals residing in the central plateau mainly Jharkhand, Bihar, Chhattisgarh, Madhya Pradesh, Orissa, West Bengal, Uttar Pradesh, Andhra Pradesh and Maharashtra. This insect has a long list of 20 host plants but reared mostly on sal (Shorea robusta Roxb.) arjun (Terminalia arjuna Bedd.) and asan (T. tomentosa W.&A.), in the natural forests or plants systematically developed in degraded forest areas. Sal forests provide base for the collection of a large quantity of naturally grown cocoons, Tasar silkworms are reared outdoors and are predominantly bivoltine and trivoltine in nature. The first crop is raised during July-August (seed crop) whereas second crop is reared during September-October (commercial crop). The average annual income due to the collection of tasar cocoons in central India is estimated to be low as compared to that of other tasar states. The probable reasons are scattered distribution of food plants on which the silkworm grows, the absence of profitable plantations, lack of suitable breed and proper knowledge of breeding and multiplication techniques. Tropical tasar, a potential NTFP has vast potential in central India.Keywords

The present paper reports the assessment of damage caused by gall insect Leptocybe invasa Fisher&LaSalle (Hymenoptera : Eulophidae) in eucalyptus. Based on the survey of forest nurseries and plantations of eucalyptus in Madhya Pradesh, the infestations of gall insect revealed wide variations in respect of age of seedlings and saplings. The infestation percentage of L. invasa varied from 20% in one month age of old seedlings and 100% in one year old seedlings in nurseries and 80-100% infestation was recorded in six months old plantations. The intensity of damage was observed to be very severe in seedlings and saplings. The production of galls in relation to early growth of seedlings revealed that there was an increase in number of galls formed irrespective of leaves, petioles and stems. The relative susceptibility to the gall insect varied among seed raised genotype and hybrid eucalyptus, which advocates the differential response of gall wasp in regard to genotype. All these observations clearly indicate that L. invasa is a major gall making insect pest of eucalyptus especially in seedling/sapling stage.Keywords
