Grewia optiva is an important fodder tree in Solan District of Himachal Pradesh. It forms an important component of agro forestry systems in the mid hill region because of its multipurpose use as fodder, fuel and fibre. Its leaves are damaged badly by different insects leading to huge losses of green fodder. The different insect pests found feeding on G. optiva are Mimastra cyanura, Myllocerus setulifer, Apoderus spp. Lygropia obrinusalis, Adoretus bimarginatus etc. These pests take heavy toll of the foliage and results in huge losses to the farmers.Keywords

Robinia pseudoacacia commonly called 'Black locust' is an exotic tree which was introduced in the country in the late nineteenth century and the plantations done in Shimla forests did well. It is becoming an important component of agroforestry systems in mid-hill regions, especially in Solan District of Himachal Pradesh. It is valued for leaf fodder, timber and as honeybee flora. Being an exotic tree, it is not having its traditional pests but some insects have been encountered feeding on different parts of this tree. Among them, Chaffer beetles were found to feed profusely on the foliage of this tree and take heavy toll of the leaves. Cyclopelta siccifolia (Hemiptera : Pentatomidae) was recorded to be the major pest associated with this tree. Its nymphs and adults were observed to suck the sap profusely from the stem and branches of the tree. Another pentatomid bug Nezara viridula was found to feed on the leaves of R. pseudoacacia. Bagrada cruciferarum adults were also encountered feeding on the leaves. Some other pests of minor importance were also observed to feed on this tree.Keywords

Locastra muscosalis Walker (Lepidoptera : Pyralidae) is a serious pest of Pistacia, Apple and Poplars. Larvae of this pest make the webs by uniting the leaves together with the help of silken threads secreted by Lannea grandis and feed voraciously on the leaves of host trees while living inside these webs. The damage caused by this insect is upto an extent that some times the whole tree is defoliated and it is not able to bear the leaves for the remaining season. During the biological study of this pest an egg larval parasitoid has been found to kill this pest. The parasitoid has been identified as Dolichogenidea sp. The parasitoid larva come out of the host body and make a white cocoon before pupation. The adults were black in colour and having transparent wings. The detailed biology of the parasitoid is presented.- Diorhabda lusca, Maulik (Coleoptera : Chrysomelidae), a Serious Pest of Celtis australis in Low and Mid-hills of Himachal Pradesh

Celtis australis Linn. leaves are damaged severely by the larvae and adults of Diorhabda lusca Maulik. These brown coloured beetles started appearing in the last week of March with the new flush of leaves. In a period of 8 months i.e. from March to October, the insect completed 4 generations and the adults of the 4th generation underwent hibernation to resume the activity in next March. The biology, nature and extent of damage is presented in this paper.- Some Important Insect Pests of Poplars in the Western Himalayas and their Management

Poplars hold an important place in the agroforestry systems because of their multiple use, fast growing nature and short rotation. Tbey are being grown on large scale in the plains of nortbern India, valley area of Himachal Pradesh and Jammu & Kashmir. Different Poplar clones being grown on these areas are invariably attacked by a number of insect pests. Various insect species invade Poplar plant parts right from the nursery stage to the maturity of the crop. Some of the important inseet pests infesting these trees include Apriona cinerea, Eucosma glaciuta, Plagiodera versicolora etc. They not only affect the growth and render them unfit for proper utilization but also sometimes threat their survival. An account of insect pests associated with Poplars in western Himalayan region in respect of their incidence, nature and extent of damage and management strategies have been discussed in the text.- Management of Locastra muscosalis Walker (Lepidoptera: Pyralidae) Using Certain Synthetic Insecticides and Physical Methods

The efficacy of three synthetic insecticides and three neem products was evaluated in the field for the control of Locastra muscosalisWalker (Lepidoptera: Pyralidae) affecting Pistacia integerrima Stew ex. Brandis trees growing in the campus of Dr. Y.S. Parmar University of Horticulture and Forestry Nauni, Solan (H.P.). Along with these insecticides, a physical practice of removing the egg masses was also evaluated as a control method. Removal of egg masses was found to be the most successful method in controlling this pest. Amont the various chemicals used Endosulfan 35EC (1.5ml/lt) was found to be the most effective followed by Monocrotophos 36SL (2.5ml/lt) and Chlorpyriphos 20EC (2.5ml/lt). The neem products used to control the pest were found to show negligible effect in controlling the pest population when compared with the synthetic insecticides.- Role of Insect Pests in the Mortality of Kikar and Shisham in Punjab

In the recent past, large scale mortality of Kikar (Acacia nilotica Willd.) and Shisham (Dalbergia sissoo Roxb.) was observed in Punjab and the adjoining states. These species are grown extensively in various sites in Punjab, on roadsides drain sides, canal sides, etc. Termites were found to be the common enemies of both the trees. Celosterna scabrator grubs were found to be associated with kikar trees throughout Punjab. In addition, Plecoptera reflexa was found associated with shisham and lndarbella quadrinotata was found to cause damage to kikar trees. These insects are discussed in detail in this paper.- Insect Pests of Robinia pseudoacacia and Paulownia tomentosa in Solan District of Himachal Pradesh

Pistacia integerrima is a tree of great economic importance because of its ornamental and medicinal values and as its wood is used for making furniture. The defoliation caused in this tree hampers the production ofthe leaf galls formed on this tree which are capable of curing various diseases. Out of different defoliators, Locastrti muscosalis is the most important one which takes heavy toll of the foliage. This pests is reported for the first time on this tree. It is gregarious pest which live on the tree by making webs and is capable of defoliating the whole tree. The eggs are laid in the last week of June. 1st, 2nd and 3rd instar larvae are gregarious in hebaviour, but in the 4th and 5th instar the larvae change to solitary hebaviour. Larvae hibernate inside the silken cocoon from September onwards upto next June when pupation take place inside the cocoons made for hibernation. The black coloured adults with greenish tinge emerge in last week of June. Its detailed biology is being reported.- Incidence and Control of White Grubs in Poplar Nurseries at Nauni in Himachal Pradesh

Poplars are highly preferred and profitable agro-forestry trees propagated by planting entire transplants raised in nurseries. The plants in the nursery suffer damage by White grubs which feed on its ischolar_mains. In the experiment conducted to control the pest by using Phorate l0G and Chlorpyriphos in different concentrations , by administering them in two instalments , one at the time of planting and cuttings , and the other 2 months after that , it was found that Phorate l0G @ 20g/m2 was more effective in controlling the pest , although Chlorpyriphos @ 2ml/lt and other concentrations were almost equally good , and resulted in better growth parameters i.e. height and collar diameter.- Potential of Nimbecidine in the Control of Locastra muscosalis.

Kikar (Acacia nilotica Willd.) and Shisham (Dalbergia sissoo Roxb.) are integral part of agro-ecosystem in the plains of North-West India. In the recent past large scale mortality of these trees was observed in this area and other parts adjoining the North-West and North-East Himalayas. So as to investigate the different mortality factors of these trees in the State of Punjab some of the areas with large scale of mortality of these trees were surveyed during the year 2001 determining the insect-pest association. It was found that grubs of Coleopteran beetles were most predominant in dead and drying trees in most of the areas. However in certain case termites and bark eating caterpillars were also found associated with Kikar and Shisham trees. A detailed account of insect-pests associated with Kikar and Shisham trees and survey report in particular have been discussed in the text.- Bacillus circulans a Promising Biocontrol Agent of Locastra muscosalis a Defoliating Pest
