Chemical Methods of Fight Against Monarthropalpus Buxi Geoff. Species

The Monarthropalpus buxi Geoff. lives on Buxus senpenvirens bushes of landscaping in our country- in adult stage for 1 month only, whilst in larva stage for almost 9 months. The most poignant damages are made by larvae, which gnaw within the interior of the leaf, determining a goffering aspect of the leaf on its inferior side, yellow-rusty in colour. The experiment started on May 10, 2012 and ended on May 18, 2012. With the purpose of fighting chemically against this pest, treatments have been undergone on five chemical products, on five series of the Buxus senpenvirens bushes in the city of Cluj-Napoca. The pest population has been monitored after 24 hours, 48 hours, and also after 7 days from spraying, by counting the number of adults on the coloured panels (white, blue, yellow, green). It has been proved that the product Karate-Zeon has registered the best results in the fight against the adult population of this pest, with a mortality rate of 100% after 7 days from spraying. Also, the systemic products have registered a fairly high mortality rate in larvae of the Monarthropalpus Buxi Geoff. . According to personal results, the commercial product KarateZeon is recommended for fighting the adult stage, and Confidor 200 SL, Actara 25 WG, Calypso 480 SC and Mospilan 20 SG for larva stage of the Monarthropalpus buxi Geoff. pest, with the purpose of maintaining the Buxus senpenvirens species in landscaping.
