Cytogenetic and molecular analysis of the holocentric chromosomes of the potato aphid Macrosiphum euphorbiae (Thomas, 1878)
Cytogenetic and molecular investigations on the holocentric chromosomes of the aphid Macrosiphum euphorbiae (Thomas, 1878)have been carried out using silver staining and C-banding (followed by chromomycin A3 and DAPI staining) in order to improve our knowledge about the structure of aphid chromosomes. The C-banding pattern is peculiar since only the two X chromosomes and a single pair of autoso...
متن کاملHost Plant Volatiles and the Sexual Reproduction of
In late summer, heteroecious aphids, such as the potato aphid, Macrosiphum euphorbiae, move from their secondary summer host plants to primary host plants, where the sexual oviparae mate and lay diapausing eggs. We tested the hypothesis that volatiles of the primary host, Rosa rugosa, would attract the gynoparae, the parthenogenetic alate morph that produce oviparae, as well as the alate males ...
متن کاملPotato aphid, Macrosiphum euphorbiae (Thomas), in tomatoes: plant canopy distribution and binomial sampling on processing tomatoes in California.
A binomial sampling method for the potato aphid, Macrosiphum euphorbiae (Thomas), on processing tomato plants, Lycopersicon esculentum (Mill), is proposed. Relationships between mean number of M. euphorbiae per leaf and proportion of leaves infested [P(I)] with M. euphorbiae for both upper and interior leaves of the processing tomato varieties 'Alta' and 'Halley' are presented. A split-plot des...
متن کاملProteomes of the aphid Macrosiphum euphorbiae in its resistance and susceptibility responses to differently compatible parasitoids.
Host insects are either susceptible or resistant to parasitoids, where resistant hosts express immunity factors and compatible parasitoids express virulence factors that may reveal the manipulation of susceptible hosts. Using proteomics we compared responses of the same host, the aphid Macrosiphum euphorbiae, challenged by a well-adapted parasitoid Aphidius nigripes or by a less adapted relativ...
متن کاملinteractions of transgenic-bt potato resistance to colorado potato beetle with the fitness and behavior of the potato aphid macrosiphum euphorbiae
the performance and flight behavior of the potato aphid macrosiphum euphorbiae was studied on the 'superior-bt' line transgenic for the cryiiia toxin of bacillus thuringien-sis (bt), resistant to the colorado potato beetle; and non transformed 'superior' line which served as control. mortality of the treated aphids was negligible and potato lines did not affect the development time of m. euphor...
