Mercury poisoning is a type of metal poisoning due to exposure to mercury. [3] Symptoms depend upon the type, dose, method, and duration of exposure. [3] [4] They may include muscle weakness, poor coordination, numbness in the hands and feet, skin rashes, anxiety, memory problems, trouble speaking, trouble hearing, or trouble seeing. [1]
They attach themselves to the plant and secrete a powdery wax layer (hence the name "mealy" bug) used for protection while they suck the plant juices. The males are short-lived, as they do not feed at all as adults and only live to fertilize the females. Male citrus mealy bugs fly to the females and resemble fluffy gnats.
Entomophagy in humans or human entomophagy describes the consumption of insects (entomophagy) by humans in a cultural and biological context. The scientific term used in anthropology, cultural studies, biology and medicine is anthropo-entomophagy. [1] [2] Anthropo-entomophagy does not include the eating of arthropods other than insects such as ...
Chemicals like alcohol and formalin can destroy nervous tissue but are not humane by themselves and should be preceded by other means of anaesthesia. [ 1 ] : 76 Ethyl Acetate (EtOAC) or Sodium Cyanide (NaCN) are and were commonly used field chemicals in conjunction with a kill jar for collecting insect specimens by many entomologists.
[1] [5] The male constructs a cottony cocoon for pupation, and the female does not. [1] The citrus mealybug looks very similar to the vine mealybug (Planococcus ficus), and the two species are mainly distinguished by the arrangement of pores and tubular ducts on the tiny body of the female. This similarity can pose a problem in agriculture.

Methanol has a moderate to high toxicity in humans. As little as 10 mL of pure methanol when drunk is metabolized into formic acid , which can cause permanent blindness by destruction of the optic nerve . 15 mL is potentially fatal, [ 1 ] although the median lethal dose is typically 100 mL (3.4 fl oz) (i.e. 1–2 mL/kg body weight of pure ...
