AbstractMicroplitis mediator (Haliday), a braconid parasitoid reared on the bertha armyworm, Mamestra configurata (Walker), entered diapause at 16 °C and a 12L:12D (100%) or 14L:10D photoperiod (99%) but not at 16 °C or 21 °C under a 16L:8D photoperiod or at 21 °C and a 12L:12D photoperiod. Diapause development was accelerated by cold treatment; adults emerged from diapause more rapidly with increasing duration of cold exposure at least up to 120 days. The main pupation site was found to be on senescent canola leaves which formed a leaf litter on or near the plants. Nearly all unparasitized fourth-instar hosts (98–100%) were found on host plants, whether the conditions induced diapause or not. Only 16–23 and 0% of parasitoids pupated on host plants under conditions of non-diapause or diapause induction, respectively. Because the pupation site of the parasitoid depends on movement of the host, these results suggest that mature parasitoid larvae modify movement of their host.

Land treatment is defined as the hazardous waste management technology related to application and incorporation of waste into the defined treatment zone of the soil where will occur the degradation, transformation and immobilization of the constituents contained in the applied waste, to ensure protection of surface water and groundwater. This paper describes some criteria for site selection of land treatment facilities used by petroleum refineries, as well as the engineering design, management practices to optimize the process and closure and post-closure techniques.

The selection of breeding habitat is of prime importance for individual fitness. Among birds, natural selection should favour the ability to recognize and select habitat suitable for nesting and rearing chicks. This study compares the characteristics of Sabine's Gull, Xema sabini (Sabine, 1819), nest sites with random points across a coastal tundra environment on Southampton Island, Nunavut, Canada. The availability of terrestrial invertebrate prey was also examined among habitats. Sabine's Gull nests were nonrandomly distributed in relation to vegetation, substrate, and proximity to water. Gulls nested within approximately 1 km of the coastline and selected sites with the greatest proportions of moss and standing water (i.e., they nested close to the edge of small freshwater ponds near shore). However, there were no detectable differences in characteristics between successful and unsuccessful nests within preferred habitat. The dynamics of terrestrial invertebrate prey communities varied between years, but the volume of invertebrates in Sabine's Gull nesting habitat was intermediate between the most productive habitats and the least productive habitats in both years. However, nest-site selection in Sabine's Gulls may also be influenced by the availability of aquatic invertebrates (not examined in this study) and their proximity to the marine coastline, where chicks are taken to be reared.
