Intraspecific competition of Glyptotendipes paripes (Diptera: Chironomidae) larvae under laboratory conditions
Original language description
Glyptotendipes paripes larvae were reared in wells of tissue culture plates, in groups of 2, 4, 8, 16, and 32 (representing densities of about 1,300, 2,600, 5,200, 10,400, and 20,800 larvae per m2, respectively). Larval groups were supplied with one of two concentrations (low or high) of food and larvae were individually observed to eventuate the effects of density on mortality, growth, development, behavior, and adult body size. Increased larval densities resulted in higher mortality, as well as slowerlarval growth and development. The distribution of developmental time became flatter at higher density, with a wider range of values, or even became bimodal. This was a consequence of the most rapidly developing individuals at higher densities emergingas adults sooner than the fastest developing individuals at lower densities, although overall mean developmental time was longer at higher densities.
