Última Sample size for monitoring sirex populations and their natural enemies PFB - Pesquisa Florestal Brasileira Penteado, Susete do Rocio Chiarello; Oliveira, Edilson Batista de; Iede, Edson Tadeu. The woodwasp Sirex noctilio Fabricius (Hymenoptera: Siricidae) was introduced in Brazil in 1988 and became the main pest in pine plantations. It has spread to about 1.000.000 ha, at different population levels, in the states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo and Minas Gerais. Control is done mainly by using a nematode, Deladenus siricidicola Bedding (Nematoda: Neothylenchidae). The evaluation of the efficiency of natural enemies has been difficult because there are no appropriate sampling systems. This study tested a hierarchical sampling system to define the sample size to monitor the S. noctilio population and the efficiency of their natural enemies, which was found to be perfectly adequate.

Damages caused by Gryllus sp. in young seedlings of Eucalyptus grandis were analysed. Threeexperimental groups were tested: Group 1 with 7 days-old and stem diameter of 2.5 mm seedlings; Group 2with 49 days-old and 3.33 mm diameter seedlings; and Group 3 with 80 day-old and diameter of 5.75 mm. Eachgroup consisted of 12 plants isolated in a cage with a couple of crickets for 15 days. The following daily evaluationswere made: absence of damage; superficial signs of chewing; deep signs of chewing and stem cuts. Diameter andage influenced the occurrence and intensity of damage.
