The tawny crazy ant [2] [3] [4] or Rasberry crazy ant, [2] Nylanderia fulva, is an ant originating in South America. Like the longhorn crazy ant (Paratrechina longicornis), this species is called "crazy ant" because of its quick, unpredictable movements (the related N. pubens is known as the "Caribbean crazy ant").
The acidopore is a component of ant anatomy; a round orifice located on the abdomen encircled by hairs which typifies the subfamily Formicinae.The conical structure connects to the posterior end of an ant's gaster where formic acid and other hydrocarbons are formed, collectively comprising the venom.
The jack jumper ant (Myrmecia pilosula), also known as the jack jumper, jumping jack, hopper ant, or jumper ant, is a species of venomous ant native to Australia.Most frequently found in Tasmania and southeast mainland Australia, it is a member of the genus Myrmecia, subfamily Myrmeciinae, and was formally described and named by British entomologist Frederick Smith in 1858.
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.
This makes many experts put some children on fire ant venom immunotherapy, while others do not. [54] [65] The recommended maintenance dose is between 0.5 mL of a 1:100 w/v 1:10 w/v WBE. [66] For fire ant venom immunotherapy, the most common maintenance dose is 0.5 mL of a 1:200 (wt/vol) dilution. [67]
While pheromones explain the pharaoh ant's foraging ability, each forager's capability to find its way back to the nest requires a different explanation. In fact, the pharaoh ant relies on geometry to show it the way home. Each fork in the trail system spreads at an angle between 50 and 60 degrees.
Myrmecia forficata, commonly known as the inchman ant, is a species of bull ant that is native to Australia. [1] The ants are recorded in the south eastern part of the country, but are most common in the Australian Alps at elevations above 300m but can be found down to sea level around Melbourne and in Tasmania.
