Book excerpt: Canola and other oilseed Brassica species are important oilseed crops in the northern Great Plains of the U.S. and Canada. As a cool season crop, canola adds diversity to cropping rotation systems. The crucifer flea beetle, Phyllotreta cruciferae Goeze, and the striped flea beetle, Phyllotreta striolata, are the most serious insect pests of canola. Crucifer flea beetle is the dominant flea beetle pest of canola. Adult flea beetles emerge in the spring and feed on the cotyledons and true leaves. When they emerge in large numbers, they can devastate a seedling canola field quickly; therefore, timely monitoring and management of this pest is important. Control costs for flea beetles in oilseed Brassica crops often exceed $300 million annually in North America.

Book Synopsis Integrated Management of Insect Pests on Canola and Other Brassica Oilseed Crops by : Gadi V P Reddy

Download or read book Integrated Management of Insect Pests on Canola and Other Brassica Oilseed Crops written by Gadi V P Reddy. This book was released on 2017-04-26. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively reviews current pest management practices and explores novel integrated pest management strategies in Brassica oilseed crops. It is essential reading for pest management practitioners and researchers working on pest management in canola and other Brassica crops worldwide. Canola, mustard, camelina and crambe are the most important oilseed crops in the world. Canola is the second largest oilseed crop in the world providing 13% of the world's supply. Seeds of these species commonly contain 40% or more oil and produce meals with 35 to 40% protein. However, its production has declined significantly in recent years due to insect pest problems. The canola pest complexes are responsible for high insecticide applications on canola. Many growers rely on calendar-based spraying schedules for insecticide applications. The diamondback moth Plutella xylostella and flea beetles Phyllotreta spp. (P. cruciferae and P. striolata)cause serious damage to canola. In the Northern Great Plains, USA, for instance, P. xylostella is now recorded everywhere that canola is grown. Severe damage to canola plants can be caused by overwintering populations of flea beetles feeding on newly emerged seedlings. Cabbage seed pod weevil (Ceutorhynchus obstrictus), swede midge (Contarinia nasturtii), and tarnished plant bug (Lygus lineolaris) are also severe pests on canola. Minor pests include aphids (cabbage aphid, Brevicoryne brassicae and turnip aphid, Hyadaphis erysimi) and grasshopper, Melanoplus sanguinipes.

Download or read book Evaluation of Flea Beetle (Phyllotreta Spp.) Resistance in Spring and Winter-type Canola (Brassica Napus). written by Julian Heath. This book was released on 2017. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is an investigation into the understanding of flea beetle (Phyllotreta spp.) resistance in spring-type and winter-type canola quality Brassica napus L.. Canola is one of the world's most widely grown oilseed crops and an economically important crop in Western Canada. Genetic resistance to this common pest would add to the available tactics for integrated pest management of flea beetles in canola. The purpose of this research was to better understand the interactions of the flea beetle with canola at key feeding times in the life cycle of the flea beetle and identify genetic components related to flea beetle herbivory on canola seedlings. The objectives were to: 1) investigate seasonal effects of flea beetle herbivory on both spring-type and winter-type canola; and 2) identify quantitative trait loci (QTL) for flea beetle herbivory in two winter-type doubled haploid (DH) populations using simple sequence repeat (SSR) markers and single nucleotide polymorphic (SNP) markers. Year and seasonal effects were noted but overall trends amongst entries were similar concluding that flea beetle feeding patterns did not change throughout its life cycle. Spring-type and winter-type germplasm reacted similarly under flea beetle feeding. As such, there does not appear to be any novel resistance mechanisms that evolved as a result of divergent growth habit types in canola. Seven QTL were identified over the iii two DH populations studied. Linkage group (LG) N13 had multiple QTL identified. The remaining QTL were located on LG N04, N06, N15 and N17. It is unknown as to what mechanisms these QTL are associated with. The results of this thesis provide insight into flea beetle-canola plant interactions and identify some genetic areas of interest related to flea beetle herbivory in canola.
