For their part, farmers have been urged to reduce the risk of combine harvesters catching fire by regularly cleaning the machinery to remove chaff and dust.
The harvester and fire ant genomes revealed for the first time that ants have genes similar to those that honeybees use to produce a "royal jelly" that they feed to one privileged larva, designating her as a queen.
Three papers published in the Proceedings of the National Academy of Sciences today describe the genome sequences of the fire ant, Argentine ant, and harvester ant, and a fourth, to be published in PLoS Genetics next month, will describe the leaf ant.
Moreover, a wireless transmission module was designed and connected to the windmill-structured energy harvester to constitute a wireless fire monitoring system.
For now, after a unilateral cease-fire on the part of the insurgents that allowed pine-cone harvesters to work on the mountains, the outpost is often under rocket or mortar fire.
Harvesters also benefit from low-intensity ground fires set by livestock herders to promote fodder or from accidental fires that spread.
Harvesters in some areas report setting ground fires to remove palm leaves that are too old and damaged to be harvested, while promoting the growth of new leaves (see also Roveta 2008).
Commercially, most harvesting is done mechanically by straddle harvesters.
We include a number of interesting and important taxa, including the invasive Argentine ant (Linepithema humile), Neotropical army ants (genera Eciton and Labidus), trapjaw ants (Odontomachus), fungus-growing ants (Apterostigma, Atta and Sericomyrmex), harvester ants (Messor, Pheidole and Pogonomyrmex), carpenter ants (Camponotus), a fire ant (Solenopsis), and a bulldog ant (Myrmecia).
