Inducible Production of Phenolic Acids in Wheat and Antibiotic Resistance to Sitodiplosis mosellana
Larvae of the wheat midge, Sitodiplosis mosellana (Géhin) feed on the surface of wheat seeds for about 10 days beginning when pollination occurs. A few wheats have a high level of antibioticExpand

Effects of flea beetles, Phyllotreta spp. (Chrysomelidae: Coleoptera), on the survival, growth, seed yield and quality of canola, rape and yellow mustard
The effects of damage by natural infestations of the flea beetles Phyllotreta cruciferae (Goeze) and Phyllotreta striolata (F.) on field plots of canola, rape ( Brassica napus L.), and yellow mustardExpand

Response of flea beetles,Phyllotreta spp., to mustard oils and nitriles in field trapping experiments
Trapping experiments were carried out near Winnipeg, Canada, in the spring of 1987 and 1988 to test attraction of crucifer-feeding flea beetles to volatile glucosinolate (GS) hydrolysis productsExpand

Patterns of resistance to three cereal aphids among wheats in the genus Triticum (Poaceae).
Forty-one accessions of wild and cultivated wheats belonging to 19 Triticum species were tested in the field for resistance to three species of aphids, Rhopalosiphum padi Linnaeus, Sitobion avenaeExpand

Sexual morph determination in the aphid, Acyrthosiphon pisum
Abstract The effects of two temperatures and a series of photoperiods on sexual morph determination in an aphid are examined. Photoperiodic response curves are presented and analysed. Female morphExpand

TROPHIC INTERACTION BETWEEN SITODIPLOSIS MOSELLANA (DIPTERA: CECIDOMYIIDAE) AND SPRING WHEAT: IMPLICATIONS FOR YIELD AND SEED QUALITY1
Abstract Larvae of the wheat midge, Sitodiplosis mosellana (Géhin), feed on developing seeds of common and durum wheats, Triticum aestivum L. and Triticum durum L. (Graminae). The trophicExpand

An interspersed refuge for Sitodiplosis mosellana (Diptera: Cecidomyiidae) and a biocontrol agent Macroglenes penetrans (Hymenoptera: Pteromalidae) to manage crop resistance in wheat
Abstract An interspersed refuge of susceptible plants in a resistant, spring-sown wheat crop was tested as a strategy to protect crop resistance against evolution of virulence by the wheat midgeExpand

Oviposition deterrence in spring wheat, Triticum aestivum, against orange wheat blossom midge, Sitodiplosis mosellana: implications for inheritance of deterrence
Some spring wheat lines are known to be antixenotic to ovipositing orange wheat blossom midge, Sitodiplosis mosellana (Géhin) (Diptera: Cecidomyiidae). The genetic basis of antixenosis, expressed inExpand

Host preferences of the flea beetles Phyllotreta cruciferae and P. striolata (Coleoptera: Chrysomelidae) for crucifer seedlings
The preferences of two flea beetles, Phyllotreta cruciferae (Goeze) and P. striolata (F.), were investigated for nine cruciferous plants and for field peas. Preference was measured by the surfaceExpand
