- Abstract
During the research period, at the Sarca stationary belonging to SCDP Iasi, were studied two walnut plantations, one represented a plantation in which was developed a technology that included the application of chemical treatments, and the other stationary was also represented by a walnut orchard in which no were applied methods of protection against diseases and pests. In order to estabilish the structure and the ecological parameters representative of the coleopters entomofauna from the two plantations, were placed six soil traps type Barber, which had as fixing liquid a salt solution (NaCl) in a concentration of 25%, but the method of tapping was also used. The material was harvested periodically, at intervals between 7 and 14 days, and at each collection the biological material from the traps was transferred from the trap to a gauze cloth, was labeled, and the fixing liquid was filled or replaced according to case. Larger, significant differences appear from one stationary to another, which indicates that the technology with the treatment scheme applied in vegetation has a great influence on the entomofauna in general.
