Comparison of two types of ecolure lure on Ips typographus (L.) (Coleoptera: Scolytidae)

Abstract

The efficiency of two types of pheromone dispensers (ECOLURE classic and ECOLURE tubus) was compared in 2008. Pheromone-baited traps were checked 13 times in 10-day intervals (this guaranteed the efficiency of ECOLURE tubus all time). ECOLURE classic trapped more beetles on average in all samples. Differences among the first 4 samples (checkings) were statistically insignificant, differences among another 9 samples were significant (used statistic tests - two choice t-test, a = 0.05 from data with normal distribution, Wilcoxon matched pairs test in the case of other data distribution).
