The present application is directed to a system and device for attraction of pests. This system comprises CO.sub.2-releasing microorganisms, and also nutrients specific to these microorganisms, and this system, or the device, comprises one or more biodegradable biopolymers and allows CO.sub.2, and optionally other attractants, to be released over a period of more than 20 days. Furthermore, the present application provides for the use of such a system or such a device for the attraction of pests, more particularly of maize or potato pests, such as larvae of the Western corn rootworm or wire worm. The present application is also directed, lastly, to methods for attracting pests, more particularly pests of maize or potatoes, such as the larvae of the Western corn rootworm, or for wire worms, with the systems or devices of the invention being positioned in the immediate vicinity of the plants, but preferably not directly on the plants.

The present invention provides a synergistic composition of a nematicide comprising of a nematicidal peptides derived from CED-4 protein sequence comprising of at least two peptides. The nematicidal peptides individually show 100% nematicidal activity at a concentration of 1 mg/ml, whereas, the combination of at least two peptides in a ratio of 1:1 shows 100% nematicidal activity at concentration as low as 0.8 mg/ml bringing a synergistic effect. This synergistic nematicidal composition is highly economical as it requires 20% less peptide concentration for 100% activity, moreover the composition is environmentally safe and non-toxic to humans and animals.

This disclosure describes a biological system of plant growth promotion, pest resistance and disease resistance by application of strains of T. viride, Trichoderma harzianum K2, Bacillus amyloliquifaciens AS2, Bacillus amyloliquifaciens AS3, or a combination thereof. These strains can be used in conventional or organic agriculture for the promotion nematode resistance when applied topically as a foliar spray or as a seed coating. The highly active strains also are expected to increase plant productivity and improve quality of fruits, vegetables, flowers or other plant products.
