Role of Waxblooms in Attachment to Brassicas by Phaedon Cochleariae
نویسنده
چکیده
Mustard beetles (Phaedon cochleariae (Fabricius)) adhered slightly better to hairy leaves than to glaucous leaves of Brassica oleracea but by far the best adhesion was to glossy leaves. Scanning electron mierographs illustrate how adhesion between the climbing setae on the tarsi of P. cochleariae and the leaf surfaces was hindered by the vertical rods and dendritic plates on glaucous leaves. The importance of the wax bloom in determining colonisation of brassicas by insects is discussed.

Impact of glucosinolate structure on the performance of the crucifer pest Phaedon cochleariae (F.)
Glucosinolates (GS) are sulfur-rich secondary metabolites found in the Brassicaceae and other related families of the order Brassicales. GS consist of structurally-related compounds with different side chains. To explore the possibility that various side chain confer divergent biological activities to individual GS, we have investigated the performance of the specialist pest beetle, Phaedon coc...
متن کاملPutative Sugar Transporters of the Mustard Leaf Beetle Phaedon cochleariae: Their Phylogeny and Role for Nutrient Supply in Larval Defensive Glands
BACKGROUND Phytophagous insects have emerged successfully on the planet also because of the development of diverse and often astonishing defensive strategies against their enemies. The larvae of the mustard leaf beetle Phaedon cochleariae, for example, secrete deterrents from specialized defensive glands on their back. The secretion process involves ATP-binding cassette transporters. Therefore,...
متن کاملConsequences of mating with siblings and nonsiblings on the reproductive success in a leaf beetle
Choosing a suitable mating partner is crucial for the fitness of an individual, whereby mating with siblings often results in inbreeding depression. We studied consequences of mating with siblings versus nonsiblings in the mustard leaf beetle, Phaedon cochleariae (Coleoptera: Chrysomelidae), on lifetime reproductive traits. Furthermore, we analyzed whether cuticular hydrocarbon (CHC) profiles a...
متن کاملBiosynthesis of isoxazolin-5-one and 3-nitropropanoic acid containing glucosides in juvenile Chrysomelina.
Stable-isotope-labeled precursors were used to establish the biosynthetic pathway leading from β-alanine towards isoxazolin-5-one glucoside 1 and its 3-nitropropanoate (3-NPA) ester 2 in Chrysomelina larvae. Both structural elements originate from sequestered plant-derived β-alanine or from propanoyl-CoA that is derived from the degradation of some essential amino acids, e.g. valine. β-Alanine ...
متن کاملIndependently recruited oxidases from the glucose-methanol-choline oxidoreductase family enabled chemical defences in leaf beetle larvae (subtribe Chrysomelina) to evolve.
Larvae of the leaf beetle subtribe Chrysomelina sensu stricto repel their enemies by displaying glandular secretions that contain defensive compounds. These repellents can be produced either de novo (iridoids) or by using plant-derived precursors (e.g. salicylaldehyde). The autonomous production of iridoids, as in Phaedon cochleariae, is the ancestral chrysomeline chemical defence and predates ...
