| Abstract: | "In the last years a significant attack increasing of codling moth was observed in the western part of Romania. In order to reduce the population of this pests a bioproduct was used named Trichotim based on entomophagous insect Trichogramma sp. Trichotim is a Romanian product certified in year 2000 with the purpose to control the pests present in various cultures such us cabbage, vineyards and fruits plantations. The study was expanded over two years (2008 and 2009), in a super intensive apple orchard of Didactical Experimental Station part of University of Agricultural Sciences Timisoara. In order to control the codling moth, the product Trichotim was used three times correlated to pest biology (two releasing of Trichogramma wasps in the time of first generation and one release in the time of second generation of the pest), releasing 300.000 wasps/ha in total, where 250.000 wasps in first generation time of the codling moth respectively 50.000 wasps in the time of second generation of the pest. The releasing of entomophagous species Trichogramma succeeded at two days after maximal flight values of Cydia pomonella L. The flight curves was realized based on pheromonal traps ATRAPOM placed in tree canopy in stage BBCH 69 (end of flowering, all petals fallen). In order to assess the efficacy of Trichotim the observation was conducted 14 days before fruit harvesting. In the plots where 300.000 wasps were released, the fruits were attacked in percent of 12,33% (efficacy 87,67%) in year 2008 and respectively 14,66% (efficacy 85,33%) in 2009. In untreated plots (control) the fruits were attacked in percent of 23% in 2008 respectively 27,33% in 2009" |
