Population genetic consequences of feeding habits in some forest lepidoptera.
BY SURVEYING VARIATION AT ALLOZYME LOCI IN SEVERAL PHYTOPHAGOUS LEPIDOPTERAN SPECIES (GEOMETRIDAE), WE HAVE TESTED TWO HYPOTHESES ABOUT THE RELATIONSHIP OF GENETIC VARIATION TO ENVIRONMENTAL HETEROGENEITY: (1) that allozyme polymorphisms may exist because of associations between genotypes and "niches" (different host plants, in this instance), and (2) that the overall genetic variation of a spe...
متن کاملWhat causes population cycles of forest Lepidoptera?
Hypotheses for the causes of regular cycles in populations of forest Lepidoptera have invoked pathogen-insect or foliage-insect interactions. However, the available data suggest that forest caterpillar cycles are more likely to be the result of interactions with insect parasitoids, an old argument that seems to have been neglected in recent years.
متن کاملEvaluation of some feeding habits of Rastrelliger kanagurta (Cuvier, 1817) in the Persian Gulf (Hormozgan Province)
The Indian mackerel (Rastrelliger kanagurta, Cuvier, 1817) is one of the commercial small pelagic fish in the Persian Gulf and Oman Sea. In the current research, feed preference index (FP), fullness index (FI), and stomach contents of Rastrelliger kanagurta were evaluated to assess the quantity and type of feed habits. A total of 573 specimens were collected randomly from Bandar - Abbas and Qes...

The Indian mackerel (Rastrelliger kanagurta) is one of the commercial pelagic fish in the Persian Gulf and Oman Sea. In the current research, food preference index (FP), fullness index (FI), and stomach contents of Rastrelliger kanagurta were evaluated to assess the quantity and type of food which this species consumes in the study area. The samples were collected randomly from Bandar - Abbas a...
متن کاملPopulation cycles of forest Lepidoptera: a maternal effect hypothesis
1. Many species of forest Lepidoptera have cyclic population dynamics. Although there are numerous potential causes, including interactions with predators, parasitoids, pathogens, and food-plant quality, strongly density-dependent interactions are often difficult to demonstrate. Both autocorrelation analysis and attractorreconstruction methods have recently been applied to a number of species' ...
