Toxicity of Ant Venom, Further Studies of the Venom from Pogonomyrmex barbatus.
SummaryAs previously suggested from earlier and cruder extraction procedures (2) and as now verified, the actual venom material is far more toxic than the earlier homogenized agent. The present work indicates that 1.29 mg/kg of the relatively pure material is equivalent to 24 mg/kg of the abdominal homogenate utilized previously(2). The pure extract is

How a Traveling Exhibition on Wasps Altered Public Perceptions
ABSTRACT Media portrays a caricature of the “evil” wasp (a flying insect), perpetuating fears developed at a young age or from individual negative experiences. Because wasps are critically important to nature and our agriculture, it is important to provide some form of education to lessen this fear.

Chemistry and Functions of Imported Fire Ant Venom
In the United States, imported fire ants are often referred to as red imported fire ants, Solenopsis invicta Buren, black imported fire ants, S. richteri Forel, and their hybrid (S. invicta × S. richteri). Due to their aggressive stings and toxic venom, imported fire ants pose a significant threat to public health, agriculture, and ecosystem health ...

Host plant use is driven by microclimate not nutritional quality in a grassland butterfly
Small Copper butterflies (Lycaena phlaeas) choose to lay eggs on host plants growing in warmer microclimates, despite lower nitrogen content. Bare ground created by European Moles increases host plant temperatures and weakens the negative relationship between nitrogen content and microclimatic warmth.

Anthropogenic linear features facilitate high‐elevation colonization. Parasitoid pressure declines markedly with elevation. Cocoon damage increases despite reduced parasitism at high elevation. Abstract The upper elevational range limits of thermophilic arthropods reflect constraints on population persistence rather than simple presence.

The fire ant Solenopsis invicta is an aggressive invasive species whose venom frequently triggers hypersensitivity reactions, including severe anaphylaxis. In endemic regions, its stings represent a significant cause of Hymenoptera-related allergy.

The use of edible insects in human food
Abstract The world population is expected to reach approximately 10 billion people by 2050, which will significantly increase global food demand and may lead to agricultural shortages and a higher risk of food insecurity. In this context, this review discusses the potential of insects as alternative sources of animal protein, addressing their ...

We evaluated demographic responses of an enclosed population of brown treesnakes to two experimental perturbations: supplemental feeding followed by removal of the adult and sub‐adult cohort 2 years later. Our results indicate that adding food to the system increased the population growth rate by 50% within 6 months and that removing the adults and ...

ABSTRACT This article examines what becomes possible for interpretive literacy research when time is treated not as a neutral backdrop but as a central problematic. We argue that research does not merely trace temporal sequences; it actively creates temporalities that shape what becomes sensible, thinkable, and sayable within literacy studies.

Insects and Survival: A Review of Primary and Secondary Defense Strategies
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.
