The CompTox Chemicals Dashboard is a freely accessible online database created and maintained by the U.S. Environmental Protection Agency (EPA). The database provides access to multiple types of data including physicochemical properties, environmental fate and transport, exposure, usage, in vivo toxicity, and in vitro bioassay.
The toxicity of hornet stings varies according to hornet species; some deliver just a typical insect sting, while others are among the most venomous known insects. [10] Single hornet stings are not in themselves fatal, except sometimes to allergic victims. [ 10 ]
Dolichovespula maculata is a species of wasp in the genus Dolichovespula and a member of the eusocial, cosmopolitan family Vespidae.It is taxonomically an aerial yellowjacket but is known by many colloquial names, primarily bald-faced hornet, but also including bald-faced aerial yellowjacket, bald-faced wasp, bald hornet, white-faced hornet, blackjacket, white-tailed hornet, spruce wasp, and ...
Digital automated identification system (DAISY) is an automated species identification system optimised for the rapid screening of invertebrates (e.g. insects) by non-experts (e.g. parataxonomists). It was developed by Dr. Mark O'Neill during the mid-1990s. Development was supported by funding from the Darwin Initiative in 1997 [1] and BBSRC. [2]
The venom of Vespa luctuosa has the highest recorded toxicity to mice of any wasp species tested. The LD 50 of the venom is 1.6 mg/kg. The toxicity (measured against mice) per weight of Vespa luctuosa venom is higher than that of the larger Asian giant hornet (Vespa mandarinia), which has an LD 50 of 4.0 mg/kg, but which is responsible for many more human deaths than Vespa luctuosa due to the ...
D. arenaria can be identified by the medially interrupted or incised apical fasciae of terga 1 and 2. [6] They are yellow in color and can be differentiated from the other yellow-colored wasps, such as D. adulterina, in its genus by the lack of black markings in the ocular sinus. [6]
Symyx acquired MDL from Elsevier in 2007 and the Toxicity database was included in the acquisition. The Toxicity database is only accessible for charge on an annual subscription base. RTECS is available in English, French and Spanish language versions, offered by the Canadian Centre for Occupational Health and Safety. The database subscription ...
The Hierarchy of Occupational Exposure Limits, of which occupational exposure banding is a member. Occupational exposure banding, also known as hazard banding, is a process intended to quickly and accurately assign chemicals into specific categories (bands), each corresponding to a range of exposure concentrations designed to protect worker health.
