During 2001-2006, a total of 466 fogger-related illnesses or injuries were identified in the United States by the SENSOR-Pesticides program. These illnesses or injuries often resulted from inability or failure to vacate before the fogger discharged, reentry into the treated space too soon after the fogger was discharged, excessive use of foggers for the space being treated, and failure to ...
Burgessomedusa is an extinct, monotypic genus of macroscopic free-swimming cnidarians from the middle Cambrian Burgess Shale in Canada. The type species is Burgessomedusa phasmiformis. The genus was characterized by the bell-like body with about 90 short tentacles. They led a predatory lifestyle and reached a length of 20 cm.
This is widely used for sampling or studying insects in the canopy of tall forests which cannot be effectively reached. The floor below the trees are lined with plastic sheets and the fog causes insects to fall in the rain. These are collected for later study in the laboratory. [1]
The basis of any Flight Interception Trap consists of an upright placed see-through barrier under which one or more small basins are placed. The barrier may consist of such materials as plastic mesh, a transparent plastic sheet or even Plexiglas, [2] although the latter does not work well for day-active insects since it is visible to them due to its specific refraction.
The fog condenses on its back and drips into the mouthparts. Through this process, the “fog-basking” beetles can drink 40% of their body-mass. [3] The "fog-trapping" beetle (L. discoidalis) also gets its water from the fog, but it acquires it in a different manner. After foraging for the first half of the night, the “fog-trapping ...
This is a large taxon of insects. Some estimates of the species numbers suggest well over 10,000 world-wide. [2] Males are easily recognized by their plumose antennae.Adults are known by a variety of vague and inconsistent common names, largely by confusion with other insects.
A free swimming medusa, likely either a stem group to Cubozoa or Acraspeda (the clade containing Staurozoa, Cubozoa and Scyphozoa). [18] Sphenothallus sp. Staurozoa: Trilobite Beds; A problematic genus lately attributed to the holdfasts of conulariids. It was very widespread in paleozoic environments, and has been found attached to other fossils.
The adult dobsonfly is a large insect up to 140 millimetres long with a wingspan of up to 125 millimetres. [8] The female has short powerful mandibles of a similar size to those of the larva while the mandibles of the male are sickle-shaped and up to 40 millimetres long, half as long as the body. [ 1 ]
