Incorporation of thymidine into the chromosomes of aphid (Myzus persicae) embryos

Experientia, 1974
Les noyaux somatiques de embryons du puceronMyzus persicae prirent la marque de la thymidine H3 30 min apres son injection dans l'hemocoele maternelle. L'absorption des molecules de cette substance a travers l'epithelium folliculaire et les membranes de l'embryon fut donc tres rapide. Le marquage des metaphses s'est produit apres 90 min.

Supercooling of Myzus persicae in relation to gut content

Annals of Applied Biology, 1978
SUMMARYThe supercooling distribution curves of Myzus persicae varied in response to feeding position, diet and age. Unfed instar I aphids supercooled to temperatures lower than –20 °C. Feeding aphids supercooled to higher temperatures, the earlier instars on subsidiary veins supercooling to lower temperatures than the late instars and adults on the ...

Insecticide Resistance by Gene Amplification in Myzus Persicae

1992
Gene amplification in Myzus persicae permits the synthesis of large quantities of esterase that cause resistance by detoxifying a wide range of insecticides. Two, slightly different forms of esterase can be elevated and the corresponding amplified genes show much homology, but differ at the 3′ end.

Behavioural Aspects of the Neonicotinoid Resistance of Myzus persicae

2012
The peach potato aphid Myzus persicae (Sulzer) is an agricultural pest of high economic importance distributed across much of the globe. The main method of control of this pest is the application of neonicotinoid insecticides such as imidacloprid and thiamethoxam (TMX). Until recently no significant resistance to neonicotinoids was known in M. persicae.

MYZUS PERSICAE CONTROL, 1976

Insecticide and Acaricide Tests, 1977
Abstract Seed pieces were planted 4 inches apart in marl soil on Nov 18, 1975. The plots were single rows, 15 ft long, planted on 3 ft centers. Treatments were replicated 3 times in a randomized complete block design. Insecticides were applied by hand Feb 10 with a CO2 charged 2½ gal sprayer with a single nozzle. Counts were made 1 and 6
