These accusations were never proven, and modern research has shown that it is more likely that the insect arrived by other means. [1] The world did not experience large-scale entomological warfare until World War II; Japanese attacks in China were the only verified instance of BW or EW during the war. [1]
The fossils that were considered as Devonian insects, such as Rhyniognatha hirsti [17] or Strudiella devonica [18] were later reconsidered that their affinities as insects are insufficient. [ 3 ] [ 19 ] But based on phylogenic study, the first insects probably appeared earlier, in the Silurian period, [ 16 ] from stem-group crustaceans like ...
The largest flying insects today are much smaller, with the largest wingspan belonging to the white witch moth (Thysania agrippina), at approximately 28 cm (11 in). [124] Unlike birds, small insects are swept along by the prevailing winds [125] although many larger insects migrate. Aphids are transported long distances by low-level jet streams ...
While later Cold War-era allegations were propaganda, the idea of using the beetle for purposes of warfare had factual origins. During World War I, the French did actually draft plans for using the potato beetle against the Germans and in turn, during World War II, Germany worked on developing an insect army of its own, while simultaneously alleging that such a program was being carried out by ...
The insects then act as a vector, infecting any person or animal they might bite. Another type of EW is a direct insect attack against crops; the insect may not be infected with any pathogen but instead represents a threat to agriculture. The final method uses uninfected insects, such as bees or wasps, to directly attack the enemy. [74]
World War II [b] or the Second World War (1 September 1939 – 2 September 1945) was a global conflict between two coalitions: the Allies and the Axis powers. Nearly all of the world's countries participated, with many nations mobilising all resources in pursuit of total war .

The following list is incomplete by necessity, since the majority of extinctions are thought to be undocumented, and for many others there isn't a definitive, widely accepted last, or most recent record. According to the species-area theory, the present rate of extinction may be up to 140,000 species per year. [1]
