Abstract:
To develop green control techniques for
Myzus persicae via plant diversity, the selection behavior of
M.
persicae to 17 plants (
Allium tuberosum,
Brassica pekinensis,
Lycopersicon esculentum,
Tagetes erecta,
Vigna radiate,
Coriandrum sativum,
Mentha haplocalyx,
Allium sativum,
Capsicum annuum,
Cucumis sativus,
Chrysanthemum coronarium,
Brassica napus,
Apium graveolens,
Sesamum indicum,
Zea mays,
Leonurus artemisia and
Nicotiana tabacum) was compared in laboratory and Xuancheng tobacco demonstration park of Anhui Province. The effects of tobacco intercropping with corn, pepper, tomato, mung bean, sesame, wormwood, marigold on the population of
M.
persicae were analyzed. The results showed that the amount of
M.
persicae fed on tobacco leaves was higher than that on tomato, pepper, cucumber, crown daisy, rape, garlic, leek, mung bean, corn, peppermint and marigold. Comparing with tobacco,
M.
persicae preferred Chinese cabbage leaves. The amount of
M.
persicae in the field of tobacco intercropping with sesame was higher than the control. However, the amount of
M.
persicae significantly decreased in the field of tobacco intercropping with corn. Therefore, corn-tobacco intercropping system could be used to control
M.
persicae in fields.
