Larvaldensity was not precisely controlled, and with this procedure ranged between 100 and 200 individuals per vial. To prevent the occurrence of high larvaldensity, mating partners were kept in vials no longer than 4 days. By contrast, no association was found between grain weight and larvaldensity. The pattern of larvaldensity was similar to that of the eggs. Exclusion of birds from bilberry stands: impact on insect larvaldensity and damage to bilberry. In this study, high larvaldensity resulted in smaller mosquito adults. The survival of first and second instars declined as larvaldensity increased. In addition, the oviposition-deterring effects of conspecific larvae were positively density dependent, with increasing larvaldensity increasing the degree of oviposition inhibition (fig. 2). However, when larvaldensity in the field was low, the numbers of third and fourth instar larvae in each of the samples ranged from 15 to 30. Any variability in developmental times can also be due to different rearing temperatures under different conditions such as varying humidity, rearing media, and larvaldensity.

Infected adults are generally smaller than non-infected adults and have an insignificantly higher mortality rate; therefore, food supply and larvaldensity apparently play a role.

The flying form is more common in beetles that developed in conditions of high larvaldensity and high temperatures.

Clutches used to found the 10 pair and control lines were culled randomly to keep larval densities equivalent in all lines. As for egg batches, larval densities tended to be lower on alternate hill than alternate row systems. At the end of the 1999/2000 and 2000/2001 seasons, larval densities were sampled across the three adult-movement transects. Consequently, larval densities were 44.4-61.5% lower in intercrops compared to monocrops. Larval densities in foliage and tubers were significantly higher at the margins of the fields than in the centre. They depend on their larval food stores during oviposition, so a high larvaldensity in the larva stage can result in lower fecundity for females in the adult stage.
