A note on current pyrethroid susceptibility in the bird cherry-oat aphid Rhopalosiphum padi in Ireland [PDF]

open access: yesIrish Journal of Agricultural and Food Research, 2022
The objective of this study was to observe the response of the bird cherry oat aphid, Rhopalosiphum padi (Linnaeus, 1758) to field rate equivalents of insecticides, by using bioassays of vials coated with the pyrethroid, λ-cyhalothrin.

Flight behaviour of the bird cherry aphid, Rhopalosiphum padi

open access: yesPhysiological Entomology, 1991
Abstract Seasonal winged forms of the bird cherry aphid, Rhopalosiphum padi L., were flown in an automated flight chamber. During their maiden flights, autumn migrants (gynoparae) had a greater initial rate of climb than summer (exules) and spring migrants (emigrants ...

Inheritance of photoperiodic response in the bird cherry aphid, Rhopalosiphum padi

open access: yesPhysiological Entomology, 1996
Abstract. The photoperiodic induction of presexual females (gynoparae) and males of the aphid Rhopalosiphum padi (L.) was examined in single clones collected from different latitudes (N clone from Blair Atholl, 56.5d̀N 3.1d̀W; C clone from Leeds, 53.5d̀N 1.4d̀W and S clone

Effects of DIMBOA on detoxification enzymes of the aphid Rhopalosiphum padi (Homoptera: aphididae)

open access: yesJournal of Insect Physiology, 2003
The presence of glutathione transferases and esterase activity was investigated in Rhopalosiphum padi and the effects of the cereal hydroxamic acid, 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA) on these detoxification enzymes was studied. Activity of glutathione S-transferases and general esterases was determined for adult aphids feeding on a ...

Functional Analysis of a Carboxylesterase Gene Associated With Isoprocarb and Cyhalothrin Resistance in Rhopalosiphum padi (L.) [PDF]

open access: yesFrontiers in Physiology, 2018
Carboxylesterase (CarE) is an important class of detoxification enzymes involved in insecticide resistance. However, the molecular mechanism of CarE-mediated insecticide resistance in Rhopalosiphum padi, a problematic agricultural pest, remains largely ...

Transcriptomics and Alternative Splicing Analyses Reveal Large Differences between Maize Lines B73 and Mo17 in Response to Aphid Rhopalosiphum padi Infestation [PDF]

open access: yesFrontiers in Plant Science, 2017
Maize (Zea mays L.) is a staple crop worldwide with extensive genetic variations. Various insects attack maize plants causing large yield loss. Here, we investigated the responses of maize B73, a susceptible line, and Mo17, a resistant line, to the aphid

Population genetic structure and predominance of cyclical parthenogenesis in the bird cherry-oat aphid Rhopalosiphum padi in England. [PDF]

open access: yesEvol Appl, 2020
Genetic diversity is determinant for pest species' success and vector competence. Understanding the ecological and evolutionary processes that determine the genetic diversity is fundamental to help identify the spatial scale at which pest populations are
