Myrmecia (ant) encountered before. Based on five species, the median lethal dose (LD) is 0.18–0.35 mg/kg, making it among the most toxic venoms in the insect world. The toxicity of the venom may have evolved due to the intense predation by animals and birds during the day, since "Myrmecia" is primarily diurnal. In Tasmania, 2–3% of the human population is allergic to "M. pilosula" venom. In comparison, only 1.6% people are allergic to the venom of the western honeybee ("Apis mellifera"), and 0.6% to the venom of the European wasp ("Vespula germanica"). In a 2011 Australian ant-venom allergy study, the objective of
Tupolev ANT-37 Tupolev ANT-37 The Tupolev ANT-37 (or DB-2) was a Soviet twin-engined long-range bomber designed and built by the Tupolev design bureau, the design team operating under the guidance of Pavel Sukhoi. The aircraft did not enter production, but three examples of the type were used for research and record breaking flights. Based on the unbuilt Tupolev ANT-36 (DB-1) single-engined bomber, the ANT-37 was a twin-engined monoplane of stressed skin, dural construction, fitted with a high-aspect-ratio wing and tailwheel landing gear, the main units retracting into the engine nacelles. Powered by Gnome-Rhône 14K radial engines, the prototype first flew on 16
