It is difficult to estimate numbers of small active insects, particularly predators, in fruit-tree canopies because of the frequent and rapid movement of these species. The conventional method of sampling such populations requires tapping the branch to dislodge the insects which fall to a cloth tray from which they are recovered and counted. However, many species take to flight very rapidly and escape before identification is possible. A sampling method was required which would rapidly enclose a volume of the canopy without disturbing the resident population, thereby eliminating inaccuracies in the sample obtained. This note describes a remotely operated mechanical trap which can be placed on a limb in the tree canopy. The insects thus trapped can be immobilized, counted, and identified.

Highly significant genetic resources of matoa potentially for breeding program in Papua are being threatened as a result of cutting down trees for fruit harvesting and of forest exploitation for timber. Besides the loss of genetic resources facing now, other major problems should be consider for conservation and domestication of this fruit tree species i.e. lack of silviculture and agronomy knowledge for further breeding programs; matoa production only for local market; and inadequate government policy for matoa breeding program. Strategy developed for matoa conservation and domestication should also concern about time limited due to the fast loss of genetic poll. This paper provides a general overview of strategy for conservation and domestication of <em>Pometia pinnata</em> with special reference to Papua.</p>
