摘要:

There are still undeveloped regions in the world which have no honey industry, although they support a rich natural vegetation which could yield good honey crops if colonies were maintained there. Some of these regions have no road access; others present special problems of drought or high temperatures, or of native bees that are difficult to handle, or of parasites or predators. The Philippines constitute one such area, and the present article on the circumstances there may possibly provide clues that could help the development of beekeeping in other parts of Asia.

摘要:

The more selective the methods of controlling insect pests can be made, the less likely in general beneficial insects are to be destroyed along with the pest insects. A comprehensive book“Biological control of insect pests and weeds”edited by Paul DeBach, recently reported in Apicultural Abstracts, was compiled before the recent developments in the use of hormones—the most species-specific type of insecticides yet devised. The article below explains this method of controlling insect pests—which is a most hopeful one from the beekeeper's point of view.
