Oil palm (Elaeis guineensis Jacq.) apparently tolerates long-term waterlogging and numerous pneumatophores are evident morphological adaptation. The number of pneumatophores per plant is, however, quite variable. Thus we hypothesized that a higher number of pneumatophores may attenuate the stress effects on root system growth and induce higher tolerance to long-term waterlogging in oil palm seedlings. To test this hypothesis we compared morphological and physiological traits in well-watered (control) and waterlogged plants with 2?10, 30?40, 60?70, and 90?120 pneumatophores after ca. 77 days of waterlogging. Plant height was similar between control and waterlogged plants with 90?120 pneumatophores, but it was 21% lower in plants with 2?10 pneumatophores than in control. The stem diameter and bulb diameter and biomass were 16, 20 and 42% higher in waterlogged plants than in control, independent of number of pneumatophores. Similar number of leaves and leaflets were observed regardless of watering regime and pneumatophore number, but total leaflet area and leaflet biomass were higher in plants with 90?120 pneumatophores than in other plants. Root system biomass was remarkably decreased in waterlogged plants; however, such decreases were more expressive in plants with 2?10 pneumatophores. Leaf water potential, leaf gas exchange and chlorophyll fluorescence were unaffected by waterlogging. Thus, we conclude that waterlogging causes few changes in seedlings? above-ground morphology but remarkably affects root system development, mainly in those plants with lower number of pneumatophores. Regardless of pneumatophores, the stressed oil palm seedlings were able to adjust their leaf water status and gas exchange to cope properly with the imposed waterlogging.

Some species of the genus Anastrepha (Diptera: Tephritidae) are successfully man - aged by matching the sterile insect technique with parasitoid releases. Such strategies used in integrated pest management can be implemented only where insect mass-rearing programs are feasible. In this study, we show the process of domestication, rearing technology and qual - ity control data obtained from 54 generations of Anastrepha sp.1 aff. fraterculus (Wiedemann,1830) kept under fully artificial conditions. Eggs were collected by an artificial oviposition panel consisting of one side of the cage made of blue voile fabric externally covered with a thin layer of silicon rubber. They were then air-bubbled in water at 25 ºC for 48 h before seeding. Larvae were reared on the regular laboratory artificial diet with 66 % of agar reduction turning over a semi-liquid diet, which reduced costs and improved insect quality. The adult and larval diets were composed of local ingredients including hydrolyzed yeast. When large-scale production of this fly is contemplated, the critical stage is larval development. This system of artificial rearing for A. fraterculus sp.1 developed in Brazil, allows for the production of a large number of insects of excellent quality using local ingredients and less agar in diet composition than the original medium used for this species. By reducing the interval of egg collection, the system might be optimized in terms of insect yield and, therefore, meet the demands of A. fraterculus sp.1 with regard to integrated pest management purposes.
