The marsh crane fly, Tipula paludosa Mg., a new pest in British Columbia (Diptera: Tipulidae)
No full text<i>Tipula paludosa</i> Meigen was firmly established in the Vancouver area by 1965, starting in the eastern outskirts of the city. It was taken at Blaine, Wash., in 1966. By 1967 the pest had spread to the Chilliwack area. Populations of 110 ft2 were measured in 1966 and local observations were recorded of damage, oviposition, feeding, growth, and emergence. A review is included of European literature on populations, life history, weather relations, and biological, chemical and cultural controls with some speculation on the future
Final-instar larvae of two hymenopterous parasites of a wood- boring beetle, Tetropium velutinum LeConte (Coleoptera: Cerambycidae)
No full textCharacteristics of the cephalic structures, spiracles and skin of final-instar larvae of two hymenopterous parasites, <i>Helconidea occidentalis/<i> (Cress.) and <i>Rhimphoctona atrocoxalis</i> Ashm.), whose cocoons were found in galleries of the wood-boring beetle, <i>Tetropium velutinum</i> LeConte, are described and illustrated
A world list of parasites of Coccinellidae
Get PDFThe parasitic organisms attacking Coccinellidae of the world are presented in two lists: parasites of a given host, and hosts of a known parasite. Parasites listed include: 9 fungi, 1 bacterium, 8 prozoans, 9 nematodes, 2 mites, and 83 insects. Forty-three genera and 125 species of coccinellid hosts are included. Two hundred and three references are cited
A progress report on the use of female-baited traps as indicators of codling moth population
Get PDFTraps containing live female codling moths, <i>Laspeyresia pomonella/i> (L.), as lures were used to indicate native codling moth populations in 2 orchards in the Kelowna area of British Columbia. In one orchard the traps captured an average of fewer than 1 male codling moth per week with the exception of 2 traps along one side of the orchard. These 2 traps caught 45 per cent of all males trapped in the orchard, and codling moth entries were found in this vicinity. A spray to control codling moth was applied to 4 outside rows of trees on this side but the remainder of the orchard was not sprayed. No fruit injured by codling moth was found in the nonsprayed portion of the orchard. In the second orchard the traps captured an average of 5 moths per week. No sprays were applied to the trees and, at harvest, 9.3 per cent of the apples were injured by codling moth. These preliminary data indicate that traps baited with female codling moths can be used to indicate levels of codling moth populations and also to indicate if chemical control is necessary
