Change in the population dynamics of spiders with the seasonal variations in the Sugarcane fields
Abstract
In the present study, spider diversity and seasonal variation in the population dynamics was studied. A total of 192 specimens were recorded from the sugarcane fields located in the district Faisalabad (habitat-1). These specimens belong to 21 species, 10 genera and 6 families. In district Okara (habitat-2),a total of 164 specimens belong to 23 species, 11 genera and 7 families. The pitfall trapping methods was used for capturing from July through December. Maximum spider diversity was recorded in the month of August due to maximum humidity (65-70%) and temperature (35°C) suitable for the breeding of mature spiders. Lycosidae being active predator of pests was found most abundant in both studied habitats with 59.38% in Habitat-1 and 60.37% in the habitat-2. Salticidae was the second most abundant family in the both habitats. Oxypidae was considered least abundant and only one species was recorded from habitat-2. Ecological parameters including Species Richness (R), Shannon Diversity Index (H), Palou’s Evenness Index (E), and Simpson Diversity Index (D) were 27.75±2.56, 2.62± 0.23, and 0.94±0.04, 0.92±0.03 respectively for habitat-1 and 23.28±0.91,2.75±0.50, 0.91±0.071, 0.93±0.06 respectively for habitat-2. It was concluded the spiders are the predominant creatures in the sugarcane. If we recognize the feeding preference of individuals family, they could be successfully use in the agro-ecosystem for controlling the pest species.
