Pogonomyrmex occidentalis, or the western harvester ant, is a species of ant that inhabits the deserts and arid grasslands of the American West at or below 6,300 feet (1,900 m). [2] Like other harvester ants in the genus Pogonomyrmex , it is so called because of its habit of collecting edible seeds and other food items.
Pogonomyrmex badius workers transporting a seed to add to their granary Messor sp. carrying seeds into their nest. Harvester ant is a common name for any of the species or genera of ants that collect seeds (called seed predation), or mushrooms as in the case of Euprenolepis procera, which are stored in the nest in communal chambers called granaries.

Pogonomyrmex (sensu stricto) workers have the most toxic venom documented in any insects, with Pogonomyrmex maricopa being the most toxic tested thus far. [4] It has an LD 50 of only 0.12 mg/kg, compared to western honey bee venom, at 2.8 mg/kg, and comparable to cobra venom.
As of 2019, however, at least one species (Pogonomyrmex occidentalis) is legal to ship within the United States, with the exception of Alaska, California, Florida, and Hawaii. In Europe, some domestic species (such as Formica rufa ) are protected, and it is illegal to own, keep, buy, or sell these ants, or to damage their nests.
Tilling the soil, or tillage, is the breaking of soil, such as with a plough or harrow, to prepare the soil for new seeds. Tillage systems vary in intensity and disturbance. Conventional tillage is the most intense tillage system and disturbs the deepest level of soils. At least 30% of plant residue remains on the soil surface in conservation ...

Rangeland management (also range management, range science, or arid-land management) is a natural science that centers around the study of rangelands and the "conservation and sustainable management [of Arid-Lands] for the benefit of current societies and future generations".

Pogonomyrmex barbatus is a species of harvester ant from the genus Pogonomyrmex. Its common names include red ant and red harvester ant. [1] These large (5– to 7-mm) ants prefer arid chaparral habitats and are native to the Southwestern United States. [2] Nests are made underground (up to 2.5 m deep) in exposed areas.
They were observed for three minutes to see for how long the Pogonomyrmex was attacked. [5] The results were as follows: "the mean duration of aggression by the Dufour’s gland treatment was 53.3 seconds...The mean duration of aggression for the water, pygidial gland, and poison gland controls were: 143.5 seconds, and 137.2 seconds and 132.2 ...
