Latest Research on Formicidae : March – 2020

Fire Ant Mound Densities in the United States and Brazil (Hymenoptera: Formicidae)

To compare fire ant populations (Solenopsis) in North and South America, we surveyed 102 preselected roadside sites, half in the southeastern United States and half in the state of Mato Grosso do Sul, Brazil. Fire ants were considerably more abundant in the United States. [1]

The relation between caste ratios and division of labor in the ant genus Pheidole (Hymenoptera: Formicidae)

Ten species of Pheidole, representing as many species groups from various localities in North and South America, Asia, and Africa, were analyzed to probe for possible relationships between caste ratios and division of labor. [2]

The Seasonal Life Cycle of the Argentine Ant, Iridomyrmex humilis (Hymenoptera: Formicidae), in Southern California

Iridomyrmex humilis (Mayr) is seminomadic and often shows striking seasonal movements of entire field populations with unfavorable changes in environmental conditions. [3]

Antifungal Action of the Dillapiole-rich Oil of Piper aduncum against Dermatomycoses Caused by Filamentous Fungi

Aims and Study Design: Piper aduncum L. is a Brazilian plant with many biological properties attributed to its dillapiole-rich essential oil. Despite the development of antibiotics, bacterial and fungal infections are still a public health issue in the medical field. This study measured the antimicrobial activity of the dillapiole-rich essential oil of P. aduncum against pathogenic skin microorganisms. [4]

Nutrient Composition, Mineral Analysis and Anti-nutrient Factors of Oryctes rhinoceros L. (Scarabaeidae: Coleoptera) and Winged Termites, Marcrotermes nigeriensis Sjostedt. (Termitidae: Isoptera)

Introduction: The palm beetles, Oryctes rhinoceros L. (Scarabaeidae: Coleoptera) and Termites, Macrotermes nigeriensis Sjostedt, (Termitidae: Isoptera) are prominent edible insects in Nigeria. [5]
