Part 1 The desert locust - prototype migrant: locust control and migration - the background locust migration - facts and mechanisms biology and behaviour of the desert locust in relation to migration displacements of discrete locust populations locust migration, winds and weather on the intercontinental scale - the desert locust and synoptic meteorology locust numbers - the evidence and the problem of control the assessment of locust numbers and of control operations locusts at a low ebb - continuity of recession populations swarming and solitary phases outline of a recession - treatment of data - findings experience of recession forecasting current status of the Phase Theory. Part 2 Flight and migration in other major pests armyworms - larvae of formidably migrant moths sample of the armyworm problem - Sierra Leone 1979 trans-equatorial sequences of armyworm attack analogies with locusts establishing the timing and spacing of infestations in relation to the distribution of the moths forecasting in East Africa infestations - incursions of westerly winds and other early evidence moth flight - from circumstantial evidence to radar observations and marking/capture possible antecedents of armyworm attacks in West Africa - squall-line studies for WHO/ONCHO and other clues armyworm control - current approaches and some future possibilities spruce budworm - major forest problem of North America the background - problems of the economy and the environment budworm moth flight - observations by radar and aircraft. Part 3 Management of migrant pests - prospects and options, some suggestions: problems of the desert locust and other locusts of Africa African armyworm - prospects and options spruce budworm - prospects and options major migrant pests in China - possible new options for monitoring and control migrant pests and nuclear winter. Part 4 Ecology and evolution of insect flight and migration - some implications from findings on migrant pests survival value of systems of downwind redistribution migration - a single strategy implemented by a range of alternative tactics evolution of insect flight migration without navigation navigation in static populations - the honey-bee. Appendices Further notes on applications of meteorology in investigations of airbourne migration: 1 - some points of meteorological observation and analysis, surface and upper air 2 - problems of observation and interpretation of field/phenomena - some analogies from meteorological procedures 3 - hour-to-hour movements of individual swarms in relation to wind.
