The Evolution of Agriculture in Insects

Important predaceous insects of citrus aphids (Hemiptera: Aphididae) in the north of Iran

ABSTRACT- Several species of aphids cause severe damage to citrus in the north of Iran. Predatory insects play an important role in biological control of the pests in citrus orchards. In this study, potential predatory insects of citrus aphids, Aphis spiraecola, A. gossypii and Toxoptera aurantii, were identified and their seasonal population dynamics...

Investigation of Pedodiversity Indices, Soil Differentiation and Soil-Landscape Evolution in the Semi-Arid Region of Chaharmahal-Va-Bakhtiyari Province

Landscapes are considered as a series of different land units with a size, shape and location arrangement that are permanently under the influence of natural events and human activities. Understanding the dynamics and heterogeneity of landscapes and environmental changes is of great importance. In order to quantitatively analyze and interpret the factors affecting the changes in the environment...

Influence of public road proximity on ground-dwelling insect communities

Ecological studies on road’s impact on wildlife have concentrated on vertebrates although less is known of their effects on invertebrates. The current study presents public road influences on species richness, abundance, and diversity of ground dwelling insects in Arusha National Park in Tanzania. Values from pitfall traps data were generally higher in core habitat than road verge. Nine species...

The economic origins of ultrasociality.

Ultrasociality refers to the social organization of a few species, including humans and some social insects, having a complex division of labor, city-states, and an almost exclusive dependence on agriculture for subsistence. We argue that the driving forces in the evolution of these ultrasocial societies were economic. With the agricultural transition, species could directly produce their own f...
