Chir pine cones collected from different localities of Uttaranchal and Himachal Pradesh exhibit great variation in morphology (cone weight , length , width and number of scales). Light weight cones of lesser length , width and number of scales were less preferred by beetles as compared to heavy weight cones with bigger size and more number of scales.- Cicadas in Flame - Diminishing Background Music of the Forest

During a three year survey (July , 2000 - August , 2003) , 183 species of butterflies (representing 128 genera , 9 sub-families and 5 families) were recorded from 10 sites (4 km2 each) in Dehra Dun valley which represents the tropical moist deciduous Sal , Shorea robusta forest (TMDSF) zone of the lower Western Himalayas. Amongst these 46 species recorded are new records for Dehra Dun valley. Twenty-six species found here have geographical distribution restricted to the Himalayas and mountains of North-East India and Myanmar in the Indian Sub-Continent. Twenty-five butterfly species of Dehra Dun valley are 'protected' under the Indian Wildlife (Protection) Act of 1972. The species diversity of butterflies (July , 2000 - July , 2001) peaked in the valley during late April (spring) - early May (summer) which was a few weeks earlier than known to be in the hills (2000 m) of the Western Himalayas. This was followed by a slightly greater second peak during late October (post-monsoon) - early November (autumn) which was a few weeks later as known from the adjoining hills. Specific threats to butterfly habitats in TMDSF are discussed. A complete annotated list of 211 species recorded from the valley is also given.- Effect of Chir Pine Cone Beetle , Chlorophorus strobilicola (Coleoptera: Cerambycidae) on the Seed Efficiency of Pinus roxburghii

Cone and seed worm, Dioryctria abietella damages cones of Himalayan conifers. Infested cones were categorized on the basis of emergence holes into light, moderate, heavy, very heavy and severe intensities. Seed efficiency (S.E.) was found negatively correlated with the degree of attack as the degree of attack increased from light category to severe. The attack of D. abietella also hampered the development of cone, caused direct damage to seed and reduced the germeability of seed. Germination percentage decreased with increased degree of attack. Present studies help in estimating the production of seeds in the SPAs, seed orchards and seed stands of Blue pine.- New Additions to the Butterflies of Dehra Dun Valley, the Lower Western Himalayas

Control of cone worm Dioryctria abietella Denis and Schiff. Infesting cone and seed of spruce (Picea smithiana) in seed production areas was attempted. The systemic insecticides viz thimet, carbofuran, dimethoate, monocrotophos were applied at the point of drip line application in soil and through tree injection at the base of the trees in Seed Production Area (SPA) at Deoban, Kanasar Range, Chakrata Forest Division (Uttaranchal). Tree injection with monocrotophos 36 EC 100 ml with 20 cm Girth of a tree at Breast Height was found superior than the application of granular pesticides in the soil at the drip line. Tree injection could protect 86.49 per cent, cones from the attack of cone worm.- Recent Trends in Protection of Harvested Bamboos from Ghoon Borers

In India, the harvested bamboos suffer, in varying degree, from various species of ghoon borers at the felling site and under storage conditions. The severely infested bamboos are often reduced to heaps of dust, thus causing colossal loss in revenue to the growers and the industry. Protection of bamboos has all along been an important thrust area offorestryresearchsince the Second World War. Forest Research Institute has played a pioneering role in developing appropriate technologies for protecting bamboos from insects both for shorter duration (prophylactic treatment) and as well as of longer duration (preservative treatments). The paper discusses the results of some of the recent researches carried out at this Institute, more particularly the use of synthetic pyrethroids which, though easily biodegradable, have been found highly effective as prophylactic measures against ghoon borers.- Colonization, Succession and Preference for Tree Portion by Insects on Felled West Himalayan Spruce, Picea smithiana

Studies on colonization, succession and preference for tree portion by insects were carried out on felled trees of spruce, Picea smithiana trees. A total of 14 species of insects colonized the felled trees. Two species are important wood boring beetles, Tetropium oreinum and Dryocotes indicus which infest freshly felled trees. A sap/fluid feeding bug Mezira tenuicornis also feeds on the tree till the 3rd year followed by a decaying wood boring fly, Eristalis tenox in the 4th year after felling. Five species of predatory beetles were also collected. Thanasimus himalayensis, predating on T. oreinum and D.indicus; Ampedu spp. And Cucujus bicolor predating on D. indicus along with a brenthid and carabid species that are also predatory beetles. Archotermopsis wroughtonii a dead wood termite and a predatory carabid beetle colonize the tree from 5-8 years after felling. However, from 18 to 22 years after felling, 3 species of beetles that are borers of rotten wood, Hemisodrocus nepalensis, Oryctes nasicornis and Blaps socia feed on spruce. Preference for the tree portion by insects showed that during the first 2 years after felling all the three portions of the tree are colonized i.e. bottom, middle and top. While from 3 to 8 years the bottom and middle portions are inhabited by insects. However, from 18 to 22 years after felling insects infest the bottom portion of the tree.- Tent Caterpillar Epidemic in Betula Utilis Forest in Pithoragarh District of Uttar Pradesh and its Control

The introduction of Leucaena psyllid Heteropsylla cubana was detected at Kattupakkam, Tamil Nadu in February, 1988. A Survey of the pest since February, 1988 showed that the pest has spread to Tamil Nadu, Karnataka, Andhra Pradesh, Maharashtra and Madhya Pradesh. It was doing considerable damage to Leucaena from wherever it was reported. The action plan evolved by various agencies lays stress on breeding psyllid resistant species/ clones of Leucaena and biological control. The predators Curinus coeruleus and Olla abdominalis which have been released in Pan-Pacific region to control the Psyllid may not be desirable in the Indian context as they may readily predate upon lac insects. Before decision to introduce any Biological control agent is taken, host specificity of the agent should be confirmed.

Epidemic defoliation of deodar forests by Ectropis deodarae in Lolab Valley was reported in August, 1982. The population of the pest was monitored in early spring of 1983, by counting pupae on the ground per unit area, the ascending female moth stuck up on sticky bands applied to deodar trees and also larval population per twig. As the population was found to be on the increase and an epidemic was threatened a decision was taken to spray an organophosphorous compound fenitrothion from the air. Two Beaver aircrafts were used for the operation. The dispensing equipment used was boom and nozzle and the insecticide dosage was 1 litre per hectare Pre and Post-treatment counts of the pest population gave 92% kill. Non-target organisms hit by the spray were also monitored. There was no mortality of birds and other vertebrates. A good number of non-target insects including Calosoma beesoni, the predator beetle of Ectropis deodarae were also hit. The dosage can be safely reduced to 775 ml/hectare which will effectively kill tbe pest and cause less harm to predators.- Epidemic of Sal Heart-wood BorerHoplocerambyx spinicornis Newm.

Epidemic of Sal heart-wood borer, Hoplocerambyx spinicornis, was reported in 1979 from the hill resort of Pachmari, Madhya Pradesh. The very existance of Sal around Pachmari was threatened. Sal forest has great aesthetic value for this hill resort. So extensive trapping operations were carried out from 1979 to 1981 to control the borer, which brought down the incidence of attack from 57.23 per cent in 1979 to 0.75 per cent in 1981 and mortality from 12.28 per cent to 0.0 per cent which are below the tolerance levels.- Insect Rests of Bamboos and Their Control

There are large number of species of insects that attack bamboos belonging to the orders Coleoptera, Lepidoptera, Orthoptera and Hemiptera. Of the defoliators, greater leaf roller Pyrausla coclesalis is the most important occurring in epidemic. In post-monsoon season. Other defoliators are P. bambucivora, Pionia flavofimbriata, Massepha absolutalis, Heiroglyphus banian and poecilocerus pictus. The defoliators can be controlled by spraying/dustlng insecticides. The bamboo weevils Cyrtotrachelus dux and Cyrtotrachelus longimanus are important shoot borers. The hispine beetle Estigmena chinensis inflicts heavy damage on Dendrocalamus strictus culms. The borers of standing bamboos are controlled by silvicultural thinnings. The orber shoot boring insects Argyroploce paragramma, Chelyophoro ceratatina, C. Striata are not important. There are many spedes of scale insects belonging to tbe genera, Chionaspis, Odonaspis and Aslerolccanium. Which attack both wild and cultivated species hut are not important. Of the sap-suckers bamboo aphid Oregma bambusae and seed bug Ochrophara occurs in epidemic form. The sap-suckers can be controlled by chemical sprays.Ghoon beetles, Dinoderus brevis, D. minutus and D. ocellaris are most destructive powder post beetles. Prophylactic .nd preservative treatments are recommended for their control. Bamboo entomology has been neglected so far except studies on ghoon beetles. Need for detailed studies on the biology, life-history, natural enemy complex and control of forest pests are emphasized.- Effect of Neem Seed Extractives on Poplar Defoliator Pygaera cupreata Butler (Lepidoptera: Notodontidae) in Laboratory

Methanol extractives of neem seed and nine chromatographic fractions (F1, - F10) were tested against poplar defoliator P. cupreata for their antifeedant activity. Preliminary studies indicate antifeedant activity by Methanol extract, Fraction 2 and Fraction 10. These three active extractives were further tested following method of Nakanishi. Five replications of ten insects each were used for test. The methanol extract and fraction 2 were found significantly effective gustatory phagodeterrent when compared to fraction 10 and controls. These extractives can be used for foliage protection of Populus deltoides against P. cupreata.Keywords

Lellumlnous tree Species are important in social forestry and wasteland development programmes' hence there is a great demand for their seeds. For raising large nursery stock' huge quantities of sound seed is required. But seed entomology of the leguminous tree seeds has long been a neglected subject. These seeds are often liable to be destroyed by insects. A large number of insects belonging to orders' Coleoptera' Lepidoptera feed on pods and seeds in nature and during storage. Most important of these are bruchid beetles of the genera Caryedon. Bruchidius and Bruchus. In most of the cases insect attack commences from the tree itself. Larvae of tortricids pyralids' gelechids and heliodenlds also cause considerable damage to pods and seeds. Short account of these injurious insects feeding on lenguminous seeds and their control measures are given in this paper. The fight against bruchids which often destroy more than half of the seeds has been unsuccessful so far because it has not been based on adequate knowledge of the biologY of these beetles aud in particular of how they infest leguminous seeds at harvest time' most of them are wrongly believed to attack only stored seeds. Entomologists must remedy the situation if rurther advances are to be made in social forestry and wasteland development.- Insect Pests of Acacia tortilis in India

Large scale plantations of Acacia tortilis are being raised in arid zones of India, owing to its suitability for stablizing and dunes and fuelwood and fodler. Very little information is available about the entomology of A. tortilis. The present study shows that, though the plantation of A. tortilis do not have serious insect problems for the present as the species is a recently introduced exotic. But many insects feeding on native acacias have adapted to A. tortilis. Most serious of them are pod and seed insects and timber borers. Among the pod and seed insect Caryedon gonogra may cause even l00% loss to seed crop. Tbe bruchid can be controlled by spraying 0.25% endosulfan/fenitrothion or 0.05/. Monocrotophos/dichlorvus water emulsion. Powder post beetles Sinoxylon anale and S. crassum attack A. tortilis timber within few weeks of its felling and convert it into dust thus rendering it useless as fuelwood. Prophylactic treatment of 1.5% lindane/endosulfan protect the timber from borer attack for nearly a year. Other insect species of minor importance and their control are also given.- Cossus cadambae Moore. (Lepidoptera: Cossidae) a New Pest of Tendu (Diospyros melanoxylon)

The problem of poor seed setting in teak seed orchard at Mohghata Bhandara Forest Project Division (Maharashtra) was reported by the Managing Director, Forest Develepment Corporation of Maharashtra and Consenator, of Forests, Research and Education,Maharashtra Major insert pests which cause direct or indirect loss to the production of teak seed are, fruit borer and inflorescence feeder Pagyda salvalis, sap sucking bug, Leptocentrus vicarius and fruit borer, Dichocrocis punctiferills Defoliator, Hyblaea puera and skeletonizer, Eutectona machaerlis were noticed feeding on inflorescence in the absence of leaves, during present investigations. In the year 1980 various insecticides tested to control the insect pests were, dimeceron 0.05% nuvacron 0.05%; anthio 0.03%. endosulfan 0.25%, fenitrothion 0.25% and sevin 025%. along with hormonr alpha nophthyl acetic acid (planofix) 20 ppm. In the year 1981, only 2 insecticides i.e. nuvacron and endosulfan, which proved better in 1980 were sprayed. Different dosayes of nvacron i.e. 0.025% and 0.125% and endosulfan 0.125% and 0.0625% were tried so as to optimise the disc of application. Alpha nephthyl acetic acid (planofix) 40 Ppm was sprayrd alongwith the higher dose of the insecticides. The studies revealed that the best results as regards production and protection of inflorescence and fruits, can be obtaioned by spraying nuvacron 36 E (0.025%) and eodosolfan 35 EC (0.125%) water emulsion together with harmone, alpha nephthyl acetic ocid (NAA) 40 ppm.- Biology, Ecology and Control of Kadam Defoliator Arthroschista hilaralis Walk.

Large-scale plantations or kadam raised by the West Bengal. Forest Department during 1962-69, in their young stage, suffered severe defoliation damage from Artkroschista hiloralis. Ecological studies of this defoliator were made in a field insectary at Chilapata, Cooch-Behar Division (West Bengal) from August to November 1971 as well as at Dehra Dun (Uttar Pradesh) during 1970-71. The defoliator has a life-cycle of 21-26 days, completing 11-12 generations in a year. Pest population begins to build up to epidemic proportion after a good amount of rains during July-August. By September the pest population reaches its peak and by 1st week of October it begins to decline. The main contributing factor of population decline is the want of high humidity supported by heavy parasitism (ca 60%) by Apanteles balleatea. Severe defoliation retards growth of young plants (2-5 year old) and repeated defoliation results in stunted growth Two parasites, A. baltealea and Cedria paradoxa, are promising agents to check the pest population increase. For the control of epidemic, mass- breeding and reiease of these two parasites (biological control) and encouragement or introduction of plants that support the collateral hosts of defoliator's parasites in or around plantations have been recommended (cultural control). If these two measures prove inaadequate treatment with 0.1% thiodan (a selective killer) or 0.1% dieldrin or chlordane water emulsion may be resorted to (chemical control).- Chemical Control of Pod and Seed Insect Caryedon Serratus (Coleoptera: Bruchidae) in Field

In the present study, an attempt was made to control pod and seed borer Caryedon serratus (Olivier) (Coleoptera: Bruchidae) infesting leguminous trees, in the field by systemic insecticides. For this two application methods Soil application and tree injection were tried. In both the methods random block designing was used taking G.B.H. (Girth at Breast Height) into consideration. The doses of insecticides were calculated according to girth class. Treatments were randomly allotted to the trees such that every girth class receives an application. In soil application method Phorate 10 G (organophosphate) was found better than carbofuron (carbamate). In tree injection method, dimethoate 30 EC and monocrotophos 36 EC, were applied and Dimethoate was found more effective.Keywords
