Wpływ współrzędnej uprawy późnej kapusty z koniczyną białą i fasolą szparagową na występowanie szkodliwej i pożytecznej entomofauny
AbstractField experiments on the effect of intercropping on pests and beneficial insects were carried out at the Mydlniki Exp. Station, and the following arrangements being applied: 1. intercropping late cabbage (cv. Amager) with white clover (cv. Podkowa) in 1983-1990. 2. intercropping late cabbage (cv. Amager) with French bean (cv. Tara) in 1966-1990. The white clover and French bean were sawn on separate plots in rows with 60 cm spacing. Cabbage seedlings were planted between the rows of white clover or French bean with the distance in the rows of 60 cm. Ground predators were sampled by pitfall trapping. Traps were placed in the central part of each plot and the samples were taken weekly for the whole growing period. The abundance of cabbage aphid, cabbage aphid parasites and predators, large cabbage white, diamond back moth and flea beetles was estimated on ten plants marked on each plot. Samples were taken weekly for the whole growing period. Observations of the injury caused by cabbage moth caterpillars were made on the day of harvesting. The total number of aphids occurring on plants intercropped with mentioned plants was 2-10 times less than in monoculture. The dense plant cover provided by intercrop was the main cause of the reductipti In the invasion and colonization by aphids, diminishing the optomotor landing response of the migrating insects. No effect of intercropping was found in the case of large cabbage white and diamond back moth although the mortality of some development stages of large cadbage white was higher when cabbage was intercropped with other plants. The number of cabbage heads damoged by cabbage moth caterpillars was significantly lower on the plots with cabbage intercropped with clover and bean. Intercropping cabbage with other plants drastically decreased the number of flea beetles as well as the damage of leaves. The total number of carabids captured on the plats with intercropping was increased by over 30 % in comparison with monoculture. the cabbage aphid parasitation was also increased when cabbage was intercropped with white clover.
