Chagas disease is caused by infection with the protozoan parasite T. cruzi, which is typically introduced into humans through the bite of triatomine bugs, also called "kissing bugs". [4] When the insect defecates at the bite site, motile T. cruzi forms called trypomastigotes enter the bloodstream and invade various host cells. [ 5 ]
Ambush bugs – subfamily Phymatinae Thread-legged bugs – subfamily Emesinae , including the genus Emesaya Kissing bugs (or cone-headed bugs) – subfamily Triatominae , unusual in that most species are blood-suckers and several are important disease vectors
The insect disease caused by the fungus is a muscardine which has been called white muscardine disease. When the microscopic spores of the fungus come into contact with the body of an insect host, they germinate, penetrate the cuticle , and grow inside, killing the insect within a matter of days.
Also known as the Chagas disease, the life-threatening illness is passed to people by this freaky little guy, called a "kissing bug" or "assassin bug." And the Centers for Disease Control and ...
Diamphidia nigroornata or Bushman arrow-poison beetle, is an African leaf beetle species in the genus Diamphidia. The larvae and pupae of Diamphidia produce a toxin used by San people as an arrow poison. [1] [2] The Finnish explorer Hendrik Jacob Wikar, who travelled in Southern Africa in 1773–1779, described the larvae as "poisonous worms".
The beetles' glands store enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. In some cases this is enough to kill a predator. [6] The main component of the beetle spray is 1,4-benzoquinone, an irritant to the eyes and the respiratory system of vertebrates.
These beetles form aggregations and feed upon foliage, buds, flowers, and fruit of roses and other ornamentals. [6] [7] Metallic flea-beetles (order Coleoptera: family Chrysomelidae) Altica species – The small, shiny and metallic Altica beetles have thickened hindlegs adapted to jumping, similar to fleas. The insects are 3 mm long and chew ...
The ladybird beetle is a beetle that preys on the beech scale insect. A fungus that parasitizes the Neonectria fungus could also be employed. The problem with using these organisms to control beech bark disease is that their impact on the disease has not been evaluated extensively. In a forest setting, controlling the beech bark disease is too ...
