“…This outcome is common after stepping in or kicicing mound (courtesy Miles Guralnick, Vespa Laboratories, Inc). (16,21). As the pustule develops, the first fluid is clear, at 24 h necrotic polymorphonuclear cells and lymphocytes predominate, and at 72 h necrotic plasma cells are most common.…”

“…This species has potential to expand its distribution further (Morrison et al 2004(Morrison et al , 2005. Due to their vicious stings, imported fire ants pose a significant threat to public health (Caro et al 1957;deShazo et al 1984;James et al 1976;Lockey 1974). They may become a menace to livestock (Sorensen and Trostle 1986) and wildlife (Allen et al 2004;Buhlmann and Coffman 2001;Cook 2003;Kopachena et al 2000;Langkilde and Freidenfelds 2010;Pedersen et al 2003).…”

Red imported fire ants, Solenopsis invicta, are significant invasive pests. Certain native ant species can compete with S. invicta, such as the little black ant, Monomorium minimum. Defensive secretions may contribute to the competition capacity of native ants. The chemistry of ant defensive secretions in the genus Monomorium has been subjected to extensive research. The insecticidal alkaloids, 2,5-dialkyl-pyrrolidines and 2,5-dialkyl-pyrrolines have been reported to dominate the venom of M. minimum. In this study, analysis of defensive secretions of workers and queens of M. minimum revealed two primary amines, decylamine and dodecylamine. Neither amine has been reported previously from natural sources. Toxicity and digging suppression by these two amines against S. invicta were examined. Decylamine had higher toxicity to S. invicta workers than dodecylamine, a quicker knockdown effect, and suppressed the digging behavior of S. invicta workers at lower concentration. However, the amount of fatty amines in an individual ant was not enough to knockdown a fire ant or suppress its digging behavior. These amines most likely work in concert with other components in the chemical defense of M. minimum.

“…The venom responsible for these reactions is a mixture of 2-methyl 6-alkyl or alkenyl disubstituted piperidines, dubbed solenopsins, and a small amount (approximately 0.1% by weight) of protein (MacConnell et al, 1971;Baer et al, 1979;Deslippe and Guo, 2000). The protein components are allergenic, and the solenopsins possess cytotoxic, insecticidal, antibiotic, and antimycotic properties (Caro et al, 1957;Blum et al, 1958;Adrouny et al, 1959;Blum and Callahan, 1960;Jung et al, 1963;Bhatkar et al, 1972;Jouvenaz et al, 1972;Read et al, 1978;Baer et al, 1979;Lind, 1982;Blum, 1988;Storey et al, 1991).…”

Patterns of venom synthesis and use in the fire ant, Solenopsis invicta

In the life of the fire ant, Solenopsis invicta, venom plays several important roles, including prey capture, defense, and antimicrobial action. Although this venom's chemistry, pharmacology, and effects on humans have been extensively studied, its patterns of synthesis and use have not. We determined the ability of different-aged workers to synthesize venom, and measured the amount of venom workers delivered per sting. Newly eclosed workers contained little or no venom in their reservoirs. The rate of synthesis was highest in workers aged 1 day after adult eclosion (1.17 mg venom/day for workers with headwidths of 1 mm), declined by 75% in workers aged 15 days (0.30 mg venom/day), and was negligible thereafter. Inducing ants to sting dummies as surrogates for humans, workers were found to deliver an average of 0.66 nl per sting, amounting to 3.1% of the average individual venom supply. Older workers (foragers) delivered less venom per sting than mid-age workers (reserves) and venom dose from nest-defenders was 55% higher in the spring than in the rest of the year. Thus, fire ant venom synthesis is limited to early life, and injected venom dose appears to be modulated. Economic explanations for the observed venom-use patterns are discussed. q
