Biological methods of weed control are alternative to chemical treatments. Biological techniques are used where no possibility for chemical spraying occurs. Rumex confertus Willd. is an example of a plant-eater which is potentially more important than chemical compounds. The objective of the study was to evaluate population dynamics and the development of Hypera rumicis L. (Coleoptera, Cucurlionidae) on Rumex confertus Willd. as well as to determine effects of the injuries on growth of a plant.

This paper shows possibility of utilization ether derivatives of (8E,10Z)-tetradeca-8,10-dienal [2-((7E,9Z)-trideca-7,9-dienyl)-1,3-dioxan (2) and 2-((7E,9Z)-trideca-7,9-dienyl)-4-hydroxy-6-heptyl-5-hexyl-1,3-dioxan (3)] as potential lures for monitoring of horse-chestnut leafminer population. The both propheromones were synthesized at the Institute of Industrial Organic Chemistry (IPO) and then tested in 2006/07 on field trials at several different sites on terrain of Mazovian province. Within the scope of these investigations, acetal 2 was checked at different doses (10, 100, 500 μg) by the pheromone trapping technique, and aldoxane 3 was used both in pheromone trapping (at the dose 50 μg) and mating disruption technique. The good attractiveness properties were obtained for both tested compounds. However, the dose of 2-((7E,9Z)-trideca-7,9-dienyl)-1,3-dioxan had to be a 10 times higher than dose of aldoxane for the same good activity.
