Autor: C. J. Hodgson
Publikováno v: Proceedings of the Royal Entomological Society of London. Series B, Taxonomy. 37:114-120
SYNOPSIS A new species of Coccus, close to Coccus subacutus (Newstead), from Malawi, and two other species of Coccus close to Coccus viridulus De Lotto, one from Egypt and the other from Malawi, are described. A new genus is erected, into which Akerm

Alien Insects: Threats and Implications for Conservation of Galápagos Islands
Autor: Stewart B. Peck, Lazaro Roque-Albelo, B. J. Sinclair, C. J. Hodgson, Bernard Landry, Charlotte E. Causton
Publikováno v: Annals of the Entomological Society of America. 99:121-143
Alien species are the principal threat to the conservation of the Galapagos Islands, but little is known about the status of nonindigenous Galapagos insects and their effects on the biota. Currently, 463 alien insect species have probably been introd

Changes and comments on the taxonomy and nomenclature of some taxa in the families coccidae, eriococcidae and pseudococcidae (Homoptera: Coccoidea)
Autor: Douglass R. Miller, C. J. Hodgson, Yair Ben-Dov
Publikováno v: Phytoparasitica. 25:199-206
Catalogues of soft scale insects (Coccidae), felt scales (Eriococcidae) and mealybugs (Pseudococcidae) will soon be placed on the World Wide Web. Before these data are made available, several taxonomic and nomenclatural changes in taxa of these famil

40Ar/39Ar geochronological evidence for multiple postmetamorphic hydrothermal events focused along faults in the southern Abitibi greenstone belt
Autor: J. A. Hanes, C. J. Hodgson, Wayne Powell, Edward Farrar, S. Mcbride, D. M. Carmichael
Publikováno v: Canadian Journal of Earth Sciences. 32:768-786
Thermal histories in the Abitibi and Pontiac subprovinces vary for three general domains: (1) zones of impermeable rock with cooling rates of >8 °C/Ma; (2) zones of impermeable rock that are spatially associated with monzogranite plutons, with appar

Conditions and timing of metamorphism in the southern Abitibi greenstone belt, Quebec
Autor: C. J. Hodgson, Wayne Powell, D. M. Carmichael
Publikováno v: Canadian Journal of Earth Sciences. 32:787-805
Regional metamorphism, ranging in grade from the subgreenschist-facies to the greenschist–amphibolite-facies transition, affects all Archean supracrustal rocks (>2677 Ma) in the Rouyn–Noranda area. Contact metamorphic minerals associated with the

Interaction between aphid resistant cowpea cultivars, three clones of cowpea aphid, and the effect of two light intensity regimes on this interaction
Autor: J. Nkansah‐Poku, C. J. Hodgson
Publikováno v: International Journal of Pest Management. 41:161-165
The performance and probing behaviour of three cowpea aphid clones were studied on four cowpea cultivars reared under bright and poor light conditions. The cowpea cultivars included two resistant (TVu 801, TVu 3000), a semi‐resistant (TVu 36) and a

Autor: G. Thottappilly, S. R. Singh, C. J. Hodgson, Julia M. F. Roberts, Louis E. N. Jackai
Publikováno v: Annals of Applied Biology. 122:57-67
Summary The effectiveness of the synthetic pyrethroids deltamethrin and lambda-cyhal-othrin in preventing (i) aphid colonisation of four cowpea cultivars with different levels of aphid resistance and (ii) the introduction and subsequent spread of cow
