Heavy Infestation

In collecting sawfly eggs, larvae, and cocoons for propagating beneficial insects at the Belleville laboratory, a heavy infestation of a pine sawfly, Neodiprion nanulus Schedl, was discovered in 1942 nine miles north of Belleville, on a 25-year-old plantation of red pine, Pinus resinosa Ait.; Scots pine, Pinus sylvestris L.; and jack pine, Pinus banksiana Lamb.From samples of the eggs collected in the spring of 1943, no parasites emerged.

Abstract The study was carried out to evaluate the possibilities to control the common pine sawfly Diprion pini L. with the use of plant protection products Mospilan 20 SP (20% acetamipryd) and Trebon 30 EC (300 g etofenprox/l). Aerial insecticide treatments were applied onto experimental plots (100 ha) in Scots pine stands, sprayed with approximately 3 l of spray solution/ha. Mospilan 20 SP at a rate 0.20 kg/ha caused 61%-76% mortality of D. pini larvae, whereas at a rate 0.25 kg/ha – 100% larval mortality. Trebon 30 EC aerial treatments at a rate 0.2 l/ha resulted in 100% larval mortality. Study results will be enclosed in the procedure of registration of the plant protection products for use in forestry.
