Tb84: Controlling The Saratoga Spittlebug In Young Red Pine Plantations By Removal Of Alternate Hosts, J. P. Linnane, E. A. Osgood Dec 1976

Tb84: Controlling The Saratoga Spittlebug In Young Red Pine Plantations By Removal Of Alternate Hosts, J. P. Linnane, E. A. Osgood

Technical Bulletins

The Saratoga spittlebug, Aphrophora saratogensis (Fitch), is a major pest of young red pine (Pinus resinosa Ait. ) and jack pine (Pinus banksiana Lamb. ) plantations in the Lake States, Ontario, and more recently in the Northeast. Although insecticides are successful in controlling the Saratoga spittlebug, the biology of the insect raises the possibility of an alternative method of control. The spittlebug requires an alternate host to complete its nymphal development. The objective of this study was to investigate the feasibility of using herbicides to control nymphal host plants of the spittlebug in red pine plantations.


Tb81: Investigations On The Life History And Habits Of Pityokteines Sparsus (Coleoptera: Scolytidae), G. P. Hosking, F. B. Knight Aug 1976

Tb81: Investigations On The Life History And Habits Of Pityokteines Sparsus (Coleoptera: Scolytidae), G. P. Hosking, F. B. Knight

Technical Bulletins

The primary objectives of this study are (1) to investigate the life history of Pityokteines sparsus (LeConte) in the Oxbow area of northern Maine; (2) to study the seasonal and daily flight behavior of the insect; (3) to investigate the food energy relations of the species.


Tb83: Insecticidal Control Of Potato Infesting Aphids In Northeastern Maine, Geddes W. Simpson, R. H. Storch Jun 1976

Tb83: Insecticidal Control Of Potato Infesting Aphids In Northeastern Maine, Geddes W. Simpson, R. H. Storch

Technical Bulletins

Aphid populations for the growing seasons of 1970, 1971, and 197 2 were variable. It is possible, however, to rate the efficacy of the various insecticides tested in controlling potato-infesting aphids in northeastern Maine. Soil applications of aldicarb and DS 15,647 and foliar application of acephate were the most effective materials tested. The insecticides phosmet (foliar) and phoxim (soil) did not provide much protection against potato-infesting aphids in these tests. Bayer 77,049, parathion, Penick SBP 1382, Sandoz-Wander 52,139 and Uniroyal 840 did not provide effective control of potato-infesting aphids at the rates used in these tests. All other insecticides tested …
