Insect Pests - Aphides, C F.H Jenkins

Journal of the Department of Agriculture, Western Australia, Series 3

The members of the aphis family are remarkable creatures both in structure and habits. They are practically world-wide in their distribution and despite their small size and apparent fragility they thrive under a wide variety of conditions and are among the most prolific breeders in the animal kingdom.

Insect Pests And Their Control, C. F. H. Jenkins

Journal of the Department of Agriculture, Western Australia, Series 3

Methods of insect control are sometimes classified under the four following headings—Quarantine, Cultural Methods, Biological Control and Chemical Treatments. Each method has its own particular part to play in preventing the spread and multiplication of insect pests and it is essential for maximum results that everyone—whether he be a commercial grower or a backyard gardener—has a general understanding of the principles involved.

Entomology, R. J. Mendenhall

Journal of the Minnesota Academy of Science

The manuscript of the inaugural address of President Winchell, delivered January, 1879, was unfortunately destroyed by fire, along with the manuscript and printed pages of the whole of the bulletin for 1878. After some delay, the most of the other manuscripts have been reproduced, and are here combined with the bulletin for 1879. The paper of Mr. Mendenhall, read at the February meeting, was consumed with other manuscripts, in the fire that destroyed Brackett's Block. A few extracts from it appeared in the Minneapolis Tribune of February 5th, 1879, and to that the Bulletin is indebted for the following.
