Abstract:
In this study, insect seasonality using Malaise traps
at eight stations was investigated from abundance collections taken between
August 1986 and July 1988 in four climatic regions and one transitional
region of Paraná State, Southern Brazil. Temperature and humidity
were also measured to represent environmental conditions at the eight
stations. One station was located in the coastal region, one in the coastal
mountain range, one in the first and third plateaus and three stations
were located in the second plateau. All insects were counted and identified
to order. Randomization-based techniques were used to assess insect abundance
variation by season for the nine most abundant taxa. An Analysis of Similarity
(ANOSIM) using stations and seasons as factors and a non-metric multidimensional
scaling (NMDS) to assess the 2-D projection of station along axes of abundance
were used to assess insect community dissimilarities. A Mantels test assessed
correlations between the abundance similarity matrix and the matrix for
the environmental factors. Of the most common orders, the most abundant
was Diptera, followed by Hymenoptera, Lepidoptera, Collembola, Homoptera,
Coleoptera, Psocoptera, Orthoptera and Hemiptera. Insect orders were generally
most abundant during the spring and summer, but least abundant during
the winter. Following ANOSIM analysis, station location and season best
explained variations in abundance. The NMDS analysis found that the coastal
station differed most from all the other stations. Humidity was positively
correlated with insect abundance.
