“…Our results may provide useful information on the heterospecific effect of S. invicta alarm pheromone. As one of the most aggressive ants, S. invicta is an effective predator and includes many insects in its diet [37,38]. Sensing the predator’s alarm pheromone has an advantage for prey since it can help prey detect the presence of the predators faster and consequently improve their survival by having more time to escape.…”

Olfaction plays a dominant role in insect communication. Alarm pheromones, which alert other insects of the same species of impending danger, are a major class of releaser pheromones. The major components of alarm pheromones in red imported fire ants, honeybees and aphids have been identified as 2-ethyl-3,6-dimethylpyrazine (2E-3,6-DP), isopentyl acetate (IPA), and E-β-farnesene (EβF), respectively. In this study, electroantennography (EAG) responses to EDP (a mixture of 2-ethyl-3,6-dimethylpyrazine and 2-ethyl-3,5-dimethylpyrazine), IPA and EβF were investigated in a wide range of insect species. Beside imported fire ants, the EDP (2-ethyl-3,6(5)-dimethylpyrazine) elicited significant EAG response from all other tested insects, including six ant species and one hybrid ant, honeybee, bagrada bug, lady beetle, housefly, small hive beetle, yellow fever mosquito, termite, bedbug, water hyacinth weevil, southern green stink bug and two aphid species. In contrast, IPA elicited significant EAG response only in the honeybee, red imported fire ant, an Aphaenogaster ant, and the water hyacinth weevil. The EβF only elicited EAG responses in two aphids, small hive beetle and housefly. The results clearly indicate that EDP can be detected by widespread insect species that did not coevolve with S. invicta and further suggested alkylpyrazine may activate multiple generally tuned olfactory receptors (ORs) across a wide number of insect species.

“…However, it is not surprising that these insects were absent in unsheltered areas of a vineyard where S. invicta were abundant. Fire ants have been reported to prey frequently on Coleopteran larvae [52].…”

Grape root borer (GRB), Vitacea polistiformis, is a root-feeding pest of grapevines in the US southeast that causes underground damage well before vines show visible symptoms. A 269-d study was conducted at 31 sites in a Florida vineyard to record short bursts of insect movement and feeding vibrations in grapevine root systems and provide information that can improve timing and targeting of GRB management efforts. Characteristic spectral and temporal patterns in the subterranean vibrations facilitated discrimination of GRB from background noise and non-targeted arthropods. Infestation likelihood of GRB at each site was estimated from previous studies relating infestation to burst rate. In all, 39% of recordings indicated low infestation likelihood. Sites with medium or high infestation likelihood were confined to a small region of the vineyard where a vine with larval feeding damage was confirmed. The restricted area suggests that the biological control or chemical treatments could be reduced elsewhere. Acoustic activity was significantly greater in fall and winter than in spring, and greater in evening than afternoon; fall evenings seemed best for GRB acoustic surveys. The GRB seasonal and circadian acoustic variation reflected phenological variation in grape root growth and nutrients and was not significantly correlated with temperature.

“…S. invicta worker densities was reported to have a negative association with all herbivores on cotton (Eubanks, 2001;Wickings and John, 2011) and with most herbivores on soybean plants (Eubanks, 2001). The red imported fire ant, Solenopsis is an important predator of boll weevil (Diaz et al, 2004;Fillman and Sterling, 1983;Sterling et al, 1984;Agnew and Sterling, 1981), beet armyworm (Diaz et al, 2004) and coleopteran and homopteran insect pests attacking sweet potato (Rashid et al, 2013).…”

Abstract:The study aimed to investigate the role of predators in preying the larvae and pupae of corn stem borer, Ostrinia furnacalis Guenee (Lepidoptera: Pyralidae) was conducted in the farmer corn field during 2011. Two plant hills each of which 6 meter away were prepared one of which unglued and the other one glued for ground and canopy predators. On each plant, 5 larvae instar-2 and or -3 were made available (2 larvae at internode near the ground surface, 1 near the corn ear, at internode between ear and tassel and at the upper top internode respectively). The experiment was carried out with 10 replications so there were 20 plant hills prepared. The experiment was also carried out with the same procedures for pupae. The predators, visit frequency and the number of preys consumed by predators were recorded. The results indicated that there were 5 groups of predators i.e., ants, spiders, cricket, Coccinella sp., Chrysopa sp. and Paederus sp. were found to visit larvae and pupae on plant corn. The ant predator visit more frequently the prey larvae and pupae on both unglued and glued plants and only this predator recorded to prey larvae with the mean of 2.5 (50%) and 1.9 (38%) and pupae with the mean of 3.2 (64%) and 3.0 (60%) in 14 h period on glued and un-glued plants respectively. The ant, Solenopsis sp. found in this study can really be promoted as biological control for Asian corn borer.
