May and again in August and September. There seems to be one 
brood only in the year. 
The female beetle lays her eggs singly, daily or at intervals of 
a few days, egg-laying lasting over a period of several weeks up to 
two months. The eggs are generally 
laid just above the root up to as much 
as six feet above the ground. Egg- 
laying commences early in April and in 
May and may occur again in the autumn, 
but usually the females oviposit in the 
spring. This beetle prefers four to eight 
year old plants, but may attack those 
of much greater age. The larvse eat 
their way between the wood and the 
bark, forming slightly winding passages Fig. 14.

grow. When mature they construct 
oval fibrous cocoons composed of wood fibres in which they pupate. 
The larvae also live inside pine cones, which they turn yellowish- 
grey. As many as three larvae may occur in a single cone. Attacked 
plants may be told by small drops of turpentine on the bark and by 
the premature death of the needles. The winter is passed in the 
beetle stage and also in the larval and pupal stages. The beetles 
hibernate in the chinks of the bark, as near the inner bark as 
possible, mostly where the root and trunk join, generally above 
ground, but sometimes below. 
Pef.vention and Teeatment. 
As there is no doubt that the Hylobius is often followed by this 
Pissodes, and that the latter does not often occur without the former, 
steps should be taken to destroy the Hylobius if it occurs ; then the 
Pissodes will cease to increase. 
The causes of Hylobius attack are (1) leaving old stumps in the 
ground and dead felled timber about ; (2) the presence of sickly 
trees from either (a) bad planting, (b) unkindly soil, or (c) growing 
the trees too close together. 
Destruction of all diseased timber (roots and all) when larvie and 
pupa? are in the tree in May and June should always be carefully 
attended to.
