The protective role of the spray mechanism of the bombardier beetle, Brachynus ballistarius Lec.

Journal of Insect Physiology, 1958
Abstract Bombardier beetles, Brachynus ballistarius Lec., subjected to controlled traumatic stimuli or to predator attacks, always responded instantly by ejecting a spray from the tips of their abdomens. The spray was not directed at random, but through rotation of the end of the abdomen was always aimed accurately toward the particular appendage or ...

Defense of bombardier beetles against avian predators

The Science of Nature, 2020
Bombardier beetles (Coleoptera, Carabidae, Brachininae) possess a remarkable defense mechanism where a hot chemical spray is released from the tip of their abdomen, with an audible explosive sound. To date, the repellent properties of these chemicals have been tested against a limited number of taxa, such as amphibians and insects.

Nonlinear Dynamics of the Bombardier Beetle

Volume 7B: 17th Biennial Conference on Mechanical Vibration and Noise, 1999
Abstract This work investigates the dynamics by which the bombardier beetle releases a pulsed jet of fluid as a defense mechanism. A mathematical model is proposed which takes the form of a pair of piece wise continuous differential equations with dependent variables as fluid pressure and quantity of reactant.

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.

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

The Science of Nature, 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 ...

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 Mechanism of the Most Primitive Bombardier Beetle (Metrius Contractus)

Journal of Experimental Biology, 2000
ABSTRACT The bombardier beetle Metrius contractus discharges its defensive secretion as a froth that clings to its body. When attacked from the rear, it allows the froth to build up over the gland openings near the abdominal tip; when attacked from the front, it conveys the secretion forwards along special elytral tracks.
