Inheritance of partial resistance to Myzus persicae in lettuce

Euphytica, 1994
The genetics of partial resistance of lettuce to Myzus persicae was studied using F1 and F2 generations of two crosses between a susceptible and partially resistant accession (Norden x Batacer and Liba x Norden) and three crosses in which both parents were partially resistant (Batavia la Brillante x Batacer, Batacer x Liba and CGN4741 x Batacer ...

Effects of Temperature on Development of Myzus persicae (Sulzer)

Indian Journal of Entomology, 2022
The effects of temperature on development of Myzus persicae (Sulzer) was investigated at five constant temperature 17, 20, 23, 26 and 29 ± 1 °C, 65 ± 5 % RH, and a photoperiod of 16:8 (L:D) hr fed on cabbage (Brassicae olerasia var. capitata) under laboratory condition using the age-stage, two-sex lifetable approach.

Screening Lactuca for resistance to Myzus persicae

Netherlands Journal of Plant Pathology, 1977
A macrotest was developed to screen rapidly many genotypes ofLactuca in the greenhouse for resistance toMyzus persicae. In this test the estimated number of aphids on certain leaves of plants artificially exposed to aphid infestation was representative for the total number of aphids per plant.

The Ecology of Myzus persicae

Annual Review of Entomology, 1969
This review has been suggested by the Scientific Committee of the In­ ternational Biological Programme as part of a project on the population dy­ namics and biological control of Myzus persicae. In order to contain this review within a reasonable number of pages, information on transmission of virus diseases is virtually omitted; it could easily form a

Reproduction and Feeding Behavior of Myzus persicae on Four Cereals

Journal of Economic Entomology, 2008
Green peach aphid, Myzus persicae (Sulzer), does not overwinter outdoors in Minnesota; it arrives each spring on low-level jet streams from the south. After arrival, anholocylic reproduction occurs on numerous herbaceous species, including many common weeds, before movement to potato, Solanum tuberosum L.

Presence of phytosterols in the food of the aphid, Myzus persicae

Journal of Insect Physiology, 1972
Six phytosterols are present in radish seedlings (Raphanus sativus) and in the excreta (honeydew) of the aphid, Myzus persicae fed on the seedlings. The possiblity that these compounds are transported in the phloem and utilized by the aphids is discussed.

Development of Variation Marker of Myzus persicae by Altitude

Korean journal of applied entomology, 2011
This study focused on the green peach aphid, Myzus persicae, as an indicator pest in Chinese cabbage cultivation to develop a genetic marker. We hypothesized that M. persicae gene flow is related to climate change. Genetic variation was analyzed using five local populations collected at different altitudes (157 m, 296 m, 560 m, 756 m and 932 m above ...

The effects of azadirachtin on feeding by Myzus persicae

1992
Azadirachtin, a tetranortriterpenoid isolated from the seeds of the neem tree (Azadirachta indica A. Juss), has strong antifeedant effects on a wide range of insects, but there is confusing evidence for its efficacy against aphids. In initial tests, azadirachtin applied systemically, (20 ppm + 0.02% Tween 80) did not deter settling and feeding by Aphis

Utilization of different sugars by the aphid Myzus persicae

Journal of Insect Physiology, 1970
Abstract Adult apterous Myzus persicae were given simple solutions of twelve different sugars. As gauged by' survival and larviposition, melezitose, raffinose, glucose, fructose, galactose, maltose, and trehalose appear to stimulate ingestion and to be utilizable. Sorbose stimulated ingestion but was not utilized.
