Numerous spruce budworm, Choristoneura fumiferana (Clem.), moths were observed and trapped in western Newfoundland between 8 and 17 July 1982. At that time about 91% of the native Newfoundland budworm population was in the 5th and 6th instars and less than 1% had pupated. Spruce budworm moths probably emigrated with the aid of suitable weather from New Brunswick to Newfoundland.

Can. Ent. 119: 4 4 3 4 7 (1987) Circulifer tenellus (Baker) has a mean preoviposition period of 13.1,8.2,6.4, and 5.0 days when held at 20, 25, 28, and 32"C, respectively. The fecundity of C. tenellus averaged 105 . O, 98.9, 115.7, and 196.9 eggs per female when held under the same temperatures, respectively. The longevity of the adult C. tenellus females when held under constant conditions of 20,25,28, and 32°C averaged 58.1,52.7,41.9, and 44.8 days, respectively. Fluctuating temperatures of 19-36°C under greenhouse conditions resulted in a mean preoviposition of 10.7 days and a fecundity rate of 163.4 eggs per female with females living an average of 96.3 days with a longevity range of 142 days.

Can. En?. 108: 601-608 (1976) Life cycles of Perisrenus pallipes (Curtis) and P . pseudopallipes (Loan), parasitoids of the tarnished plant bug, Lygus lineolaris (P. de B . ) , were investigated in an alfalfa field and in uncut weeds in the Ste. Anne de Bellevue area. In 1972, P . pallipes adults emerged in mid-May and P . pseudopallipes adults emerged in late July. The incidence of parasitism in nymphal and adult stages of the tarnished plant bug, L. lineolaris, was measured. The population of the tarnished plant bug in the weeds was more heavily parasitized than the one in the alfalfa field. The ichneumonid hyperparasite Mesochorus curvulus Thomson was also found in this area.

The common June beetle, Phyllophaga anxia (LeConte), is an indigenous pest of agricultural crops in North America (Hammond 1948; Ritcher 1949). A bionomic study and survey for natural enemies of P. anxia was conducted in southern Quebec from 1975 to 1977. Pasture soils were searched for immature stages of P. anxia, and any natural enemies found in situ were collected. A prepupa and pupae of Pelecinus polyturator (Drury) were found in the pasture on several occasions. Previously, P. polyturator had been reported as a parasite of grubs of Phyllophaga spp. (Davis 1919; Petch and Hammond 1925, 1926; Brues 1928; Hammond 1944), and its distribution ranges from Canada to Argentina (Masner 1979).
