Members of Loranthaaeae are semiparasitic angiosperms and are popularly known as mistletoes. They cause more economic loss than any other angiospermia parasites. They mostly attack dicotyledors and gymnosperms which include horticultural plants as well as forest trees. Control of mistletoes has been advocated and practised throughout the world. Gill and Hawksworth (1961) suggested (i) physical removal and (ii ) chemical control as direct control measures. Silvicultural management system like thinning and use of isolation strips have been stated to be effective in reducing the infestation and spread of dwarf mistletoes (Greenham and Hawksworth 1964 ; Hawksworth et al. 1977). Certain amount of natural control exists in some areas where particular insectsand fungi reduce the infestation (Greenham and Hawksworth 1964). Gill and Hawksworth (1961) gave brief notes on insect attack of dwarf mistletoes. Approach towards the biological control of mistletoes by insects has been indicated by Hawksworth (1971 ) and Smith and Funk ( 1980 ). Graves and Graves ( 1980) noted that the larvae of Citheronid regalis ( Citheronoiidae : Lepidoptera) feed on the leaves of Citheronid regalis ( Citheronoiidae :Lepidoptera) feed on the leaves of Phoradendron flavescens (Pursh) Nutt.

Bamboo is of great importance in
Bangladesh and stands next to wood in utility.
It is extensively used for the construction
of houses, bridges, rafters and for many
other purposes. Split bamboo is used by the villagers as a
reinforcement of mud walls,
bamboo has multiple uses.
bamboo starts shrinking during the initial
stages of drying and has shown considerable wall material and also as a
As a whole,
Unlike wood,

Bamboo produces new culms from buds on subterranean rhizomes during the monsoon, generally from early June until late August.
Expansion of culms continues until October. Blight significantly affects culms in August, the disease being at its worst by mid-November.
Subsequently, there is little or no increase in the number of blighted culms.

Diagnostic symptoms of the blight are described. Coniothyrium fuckelii Sace. and Acrenwnium strictum W. Gams were the two most commonly isolated fungi from blighted bamboos.

Artificial inoculation tests have established that A. strictum (Herb. I. M. I. 278366) is pathogenic on new branches which developed from ground layered culm cuttings of Bambusa balcooa Roxb. at the Forest Research Institute campus, and on naturally grown culm of B. vulgaris Scrad at Nowapara, Chittagong. The pathogenic ability of the fungus is discussed.

Keora wood was pulped by steaming the chips under 10 kg/cm² and 7 kg/cm² pressures each for half hour, one hour and one and half hour. The pulps were refined to two different freenesses in each case. Hardboards were made from these pulps without using any sizing materials or additives and tested for strength and water absorption properties. The boards were moderate in strength and water resistance.

During data collection for preparation of volume functions for
high forest species at Cox’s Bazar Forest Division, some photographs
of wood stacks were taken in order to find a relationship of stacked
volume versus solid wood volume. The stacks were composed of
round woods of varying sizes. The photographs in black and white
were taken from three places of Cox’s Bazar Forest Division.

A high degree of water repellency is obtained in wood modified by silanation. However, the degrading effect of HC1, formed as a by-product in the reaction, may not be fully offset by the use of acid acceptors or inert gases in the reaction. Tensile tests on microtome sections of Pinus nigra wood, treated variously with dimethyldichlorosilane, clearly show that chemical modification substantially decreases tensile properties of wood. Experiments with large specimens of the same species suggest that silanated zone is only superficial. As a result, most of the strength properties of the large specimens remain unimpaired.
