Bombardier beetle based biosensor

open access: yesBiosensors and Bioelectronics, 1996
A biosensor constructed by combining an oxygen electrode with the liquid ejected by bombardier beetles (Pheropsophus aequinoctialis) immobolized on a collagen membrane is developed for hydrogen peroxide. The sensor presents a linear range of 2.0 x 10(-4)-2.0 x 10(-3) M and a reproductibility of approximately 2%.

Defensive Spray of the Bombardier Beetle: A Biological Pulse Jet

Science, 1990
The defensive spray of the bombardier beetle Stenaptinus insignis is ejected in quick pulses (at about 500 pulses per second) rather than as a continuous stream. The pulsation may be a consequence of intermittency in the explosive chemical process that generates the spray.

Bombardier beetles of genus Brachinus Weber, 1801 (Carabidae: Brachininae: Brachinini) from India

open access: yesZootaxa, 2020
Brachinus devagiriensis sp. nov. is described from the Western Ghats, a global hot spot of biodiversity in southwest India. Detailed diagnostic features of the 27 species of Indian Brachinus with a key to the species are provided.

Spray Mechanism of Crepidogastrine Bombardier Beetles (Carabidae; Crepidogastrini)

Chemoecology, 2001
The defensive glandular apparatus of primitive bombardier beetles of the tribe Crepidogastrini (Carabidae) is described for the first time. As exemplified by two African species (Crepidogaster ambreana and C. atrata), the apparatus conforms to the basic bombardier plan, in that the glands are bicompartmented and the secretion is quinonoid (it contains ...

Spray Aiming in Bombardier Beetles: Jet Deflection by the Coanda Effect

Science, 1982
Bombardier beetles of the carabid subfamily Paussinae have a pair of flanges, diagnostic for the group, that project outward from the sides of the body. Behind each flange is a gland opening, from which the beetles discharge a hot, quinone-containing secretion when disturbed.

Biosynthetic Origin of Benzoquinones in the Explosive Discharge of the Bombardier Beetle Brachinus Elongatulus

Die Naturwissenschaften, 2020
Bombardier beetles are well-known for their remarkable defensive mechanism. Their defensive apparatus consists of two compartments known as the reservoir and the reaction chamber. When challenged, muscles surrounding the reservoir contract sending chemical precursors into the reaction chamber where they mix with enzymes resulting in an explosive ...
