A mechanical harvester for K. alvarezii cultivated in Brazil is described. It was based on the same principle
of mussels harvesting machines used in continuous system production farms in New Zealand, Australia,
the USA and the UK. The mechanical design was done in four stages: specification, conception, basic design
and detailed design. The first stage dealt with the establishment of necessary technical specifications for
design and evaluation of the next stages. Physical solutions were proposed at the second conception step
to fulfill the design specifications. At the basic design, prototype dimensions and shapes were defined
as well as materials and manufacture process. Necessary prototype parts and assemblies drawings for
the prototype production were produced at the final detailed design stage. Extractors were adapted in
design revision to Perna perna mussels and K. alvarezii (cultivated in tubular nets) farmed in Brazil to provide lighter and compact structure and manufacturing costs reduction without compromising their
robustness. Comparing design specifications and the final built mechanical harvester prototype, only mass
and manufacturing costs target values were extrapolated (30.5% and 26.1%, respectively). Field trials
will be performed for the prototype performance evaluation to assess the effects of mechanization in K.
alvarezii harvesting productivity. |

The South American rice water weevil Oryzophagus oryzae (Costa Lima) (Coleoptera: Curculionidae) is a key pest of irrigated rice in Brazil. Light traps could be used as an integrated pest management (IPM) strategy since these weevils have strong phototropism. Thus, the aim of this study was to search the attractiveness of LEDs of different wavelengths to O. oryzae to define the best light-emitting diodes (LED) arrangement to build the lamp of photovoltaic light traps. LEDs of different wavelengths were tested in a dark room with a hexagonal arena with exits to light sources. Groups of 200 insects were released in the center of the arena and captured at the end of exposure time in plastic bags placed in the exits. The LEDs in the short-wave band of the light spectrum (365 and 460 nm) and white LEDs, as well as the light mix of 365 with 460 nm or white LEDs, were attractive to O. oryzae. Beyond the LEDs with ultraviolet (UV) spectrum, the LEDs above 380 nm were the most attractive and, this way, might be used to build LED lamps of photovoltaic light traps. |
