“…Interaction between soil animals must occur and become part of the compiler of the food chain in the soil [18,19]. In all terrestrial environments, spiders occupied virtually every conceivable habitat, including the shelters and artifacts of a host of other animal [20,21]. The effect of a spider species on a pest population may be enhanced when pray population is increasing.…”

“…Spiders were then observed and photographed with a phase contrast microscope (LEICA DM 750) with a close up lens attachment to the camera with artificial illumination. The spiders were identified based on published literature and keys by comparing the morphological and taxonomical features (Tikader, 1987;Samiayyan, 2014).…”

Investigations conducted on the identification of predatory spider fauna in maize ecosystem throughout the crop growth, in Tamil Nadu Agricultural University, Coimbatore during 2013-2014 yielded around 2821 spiders, belonging to 16 species under 10 genera of 6 families from seedling to maturity stage. Majority of the spiders collected belonged to the families Lycosidae (1671 individuals), Salticidae (459 individuals), Oxyopidae (352 individuals), Gnaphosidae (178 individuals), Corinnidae (96 individuals) and Clubionidae (65 individuals). The predatory spider species dominating in the maize ecosystem included the species Lycosa barnesi, L. pseudoannulata, Pardosa birmanica, Salticus sp. and Hippasa lycosina. Dendrogram analysis of spiders revealed that the families, Clubionidae and Gnaphosidae were closely related when compared to other predatory spider families. Correlation analysis with the weather parameters showed that the predatory spider population had non-significant positive correlation with relative humidity at 14:22 hrs and negative correlation with all other weather parameters viz., maximum temperature, minimum temperature, relative humidity at 07:22 hrs, rainfall, sunshine hours and rainy days.

“…It was found that in a 14-day period one Lycosa pseudoannulata could consume approximately 17 BPH's nymphs or 15-20 adult BPH per day [11]. It inhabits at the lower part of rice plants during the daytime to prey on BPH and moves to the middle and upper sections during the night time to prey on leafhoppers [9,10,12].…”

In this work, a mathematical model is proposed to investigate the population dynamics of brown planthopper, which is a major insect pest of rice, and its natural enemies namely Cyrtorhinus Lividipennis and Lycosa Pseudoannulata. To analyse the model theoretically, the geometric singular perturbation method is employed. Conditions that differentiate dynamic behaviors exhibited by the model are derived. To illustrate our theoretical predictions, computer simulations are also presented showing that the dynamic behavior exhibited by the model correspond to the reported field observations.
