If VOR navigational equipment is required under paragraph (c)(1)(ii) of this section, no person may operate a foreign civil aircraft within the 50 States and the District of Columbia at or above FL 240, unless the aircraft is equipped with distance measuring equipment (DME) or a suitable ...
49,50 It is also possible that these movements reflect flights to nectar sources. While nectaring at the overwintering sites has previously been considered negligible due to the insufficiency of available nectar resources for the large concentration of butterflies,51 monarchs do indeed nectar on a ...
to fall at opposite ends of the spectrum: fever or fear. Chinese FDI in the United States faces challenges posed by its liability of foreignness in political, cultural, marketing, and technological aspects. Utilizing mini case studies, we herein examine the polarized responses to Chinese outward ...
This native grasshopper occurs widely in the central and western regions of the United States, and in northern Mexico; in Canada, it occurs in southern Saskatchewan and British Columbia. Within the United States, it is absent from the Atlantic and Gulf Coast region, except that it occurs in ...
Other notable flights by this craft include an around-the-world trip (1929), a flight to the North Pole (1931), and the first scheduled intercontinental passenger service between Europe and the Americas (Germany to South America, 1932–1937). Following the Hindenburg disaster (see 1936), the...
(DRBBs)” to better describe the phenomena; creates a data-driven taxonomy of objectives and motivating reasons for DRBBs; estimates a Structural Equation Model (SEM) to assess the strengths of the interconnections between reasons, themes, and objectives pursued by individuals who enact DRBBs; ...
These are referred to as “aquatic Heteroptera,” because they spend their entire life under water, except during dispersal flights. Flightless species of Nepomorpha are the most aquatic of all insects because they rarely, if ever, leave the water. There are six families of Nepomorpha in which...
Mass flights by adults take place only if air temperature is high, often about 29°C, but high densities and light wind also are required. When it is hot, grasshoppers tend to climb upward to escape the soil, which is usually considerably warmer than the air temperature. However, they ...
Ancinus is recorded from the coasts of Costa Rica and Columbia. Aquatic isopods belonging to other families may also be encountered: Exosphaeroma may sometimes be found on-relatively sheltered sands, whereas still other sphaeromid genera occur locally (e.g., Sphaeromopsis on the coast of ...
Synthetically produced pheromones are frequently used in IPM programs as described earlier to monitor adult insect flights. The direct use of pheromones as control agents has also met with some success, usually when the chemical is released over the field from dispensers with the intent of confusing...
