Biological control is a major tool for forest insect pest management. We initiated a biological control program for the Eucalyptus bronze bug, Thaumastocoris peregrinus, with the egg parasitoid Cleruchoides noackae. Parasitized eggs were imported from a mass rearing in Brazil, and a rearing colony was set up. The wasp was reared in
plastic tubes each containing ten individuals that were offered 100 eggs of the bronze bug and a solution of water and honey. During 30 generations, rearing quality parameters were compared against expected quality standards set a priori, based on information from other rearing colonies. We also assessed the effect of temperature on developmental time, measured as the first day of emergence of adult parasitoids, as well as the relation between host-egg abortion and parasitization by C. noackae, and the evolution of the sex ratio of the emergent wasps within a single generation. Field releases were made yearly during summers in commercial plantations, starting
in March 2013. Survival and emergence rates were either stable or increased throughout 30 generations. The percentage of females was slightly above 50%. Rearing at 18 °C and 20 °C took longer than at 22 °C, but productivity was similar. Host-egg abortion was increased by parasitization. The proportion of females increased as
the emergence period progressed. Field surveys in two sites revealed that the wasp survived for two years. Fieldcollected parasitoids exhibited better quality indices than individuals from the laboratory rearing. Results indicate that biological control of the bronze bug with C. noackae is feasible with this rearing and release protocol.

ABSTRACT.
The aim of this research was to obtain information on the behaviour of the species under cultivation. Seeds were sown on December 18, 1992, in a field seedbed under plastic cover. Plants were taken to the field when 15 cm high (February 18, 1993). Three lines with 47 plants each were managed independently. Plants from Line 1 were harvested on August 4, Line 2 on August 19, and Line 3 on September 13, 1993. Mean fresh weight per plant for each line was 261, 207 and 337 g, and 88, 78 and 105 g, respectively, expressed in dry weight. The estimated yields per hectare at plantation distances of 0.6 x 0.15 m, corresponded to 29000, 23000 and 37444 kg fresh plant/ha, and the equivalent in dry matter: 9778, 8667 and 11667 kg/ha. Line 3 was harvested on a second occasion (October 27, 1993) yielding 244 g fresh matter/plant or 67 g dry matter/plant. The estimated yields per hectare on this second harvest was 27111 kg fresh weight/ha or 7444 kg dry weight/ha. The average yields for the three lines in the first harvest, in addition to a second harvest shows the possibility of achieving 57000 kg fresh weight/ha or 17444 kg dry weight/ha. For plants from the first harvest, the proportion of leaves and stems was 50:50. These data are the result of a one year experience and were not analysed statistically. |
