“…Similar gene expression in thoraces has been shown by the experiments with Manduca sexta (Xu and Denlinger, 2004) and Plutella xylostella (Lee and Boo, 2005). While the expression in any organs except for SG has not been confirmed by the RT-PCR of other species, immunoreactive materials have been detected throughout a nervous system, particularly in the thoracic ganglions, of several moths using an anti-PBAN serum (Choi et al, 2004;Rafaeli, 2002).…”

“…The tissue localization and the distribution pattern of PBAN-like immunoreactive materials in the CNS of the fire ant is similar to that previously shown in moths and a fly. Three clusters of neurons with PBAN-like immunoreactivity have been detected in the SG of the fire ant, as found in many lepidopteran moths Choi et al 2004;Davis et al 1996;Duportets et al 1998;Ma and Roelofs 1995;Ma et al 1996;Sato et al 1994;Sun et al 2003;Wei et al 2008), Orthoptera (Tips et al 1993), and Drosophila (Choi et al 2001). The locations of these neuron clusters correspond to the mandibular, maxillary, and labial neurons, as demonstrated in moths and fruit flies.…”

“…In moths, the subesophageal ganglion (SG) contains three groups of neurons that produce PBAN . The ventral nerve cord and ganglia also contain PBAN-like activity (Choi et al 2004;Ma et al 1996). The SG and the ventral ganglia of other insects contain peptides that belong to the pyrokinin/PBAN family of peptides (Choi et al 2001;Predel and Eckert 2000a, b;Schoofs et al 1992;Tips et al 1993).…”

The pyrokinin/pheromone-biosynthesis-activating neuropeptide (PBAN) family of peptides found in insects is characterized by a 5-amino-acid C-terminal sequence, FXPRLamide. The pentapeptide is the active core required for diverse physiological functions, including the stimulation of pheromone biosynthesis in female moths, muscle contraction, induction of embryonic diapause, melanization, acceleration of puparium formation, and termination of pupal diapause. We have used immunocytochemical techniques to demonstrate the presence of pyrokinin/PBAN-like peptides in the central nervous system of the fire ant, Solenopsis invicta. Polyclonal antisera against the C-terminal end of PBAN have revealed the location of the peptide-producing cell bodies and axons in the central nervous system. Immunoreactive material is detectable in at least three groups of neurons in the subesophageal ganglion and corpora cardiaca of all adult sexual forms. The ventral nerve cord of adults consists of two segmented thoracic ganglia and four segmented abdominal ganglia. Two immunoreactive pairs of neurons are present in the thoracic ganglia, and three neuron pairs in each of the first three abdominal ganglia. The terminal abdominal ganglion has no immunoreactive neurons. PBAN immunoreactive material found in abdominal neurons appears to be projected to perisympathetic organs connected to the abdominal ganglia. These results indicate that the fire ant nervous system contains pyrokinin/PBAN-like peptides, and that these peptides are released into the hemolymph. In support of our immunocytochemical results, significant pheromonotropic activity is found in fire ant brain-subesophageal ganglion extracts from all adult fire ant forms (queens, female and male alates, and workers) when extracts are injected into decapitated females of Helicoverpa zea. This is the first demonstration of the presence of pyrokinin/PBAN-like peptides and pheromonotropic activity in an ant species.

Rapid progress has been made in research on insect pheromones and other semiochemicals in Korea during the last two decades. Sex pheromone compositions have been identified in several major orchard and other horticultural moth pest species and some other species in Korea, such as Helicoverpa assulta, Grapholita molesta, Carposina sasakii, Adoxophyes orana, Lyonetia prunifoliella, Phyllonorycter ringoniella, Dichocrocis punctiferalis, Ostrinia furnacalis and Peridroma saucia. Some of these identified sex pheromones have already been successfully incorporated into IPM systems, and are now being used as direct and indirect pest control means in Korea. Korean populations of many of these species showed significant differences in pheromone compositions from those reported in the neighboring countries of Japan and China, suggesting that such interpopulational pheromone polymorphism is more common across the insect world than previously thought. Sex pheromone compositions were also identified in some aphid species in Korea such as Aphis spiraecola and Tuberocephalus momonis, and it was soon found that the aphid sex pheromone components were highly attractive to their predator lacewings. The presence of kairomones responsible for attracting egg parasitoids was shown in a pheromone component, hot pepper odor and male scale factor for H. assulta, and in male accessory glands for Lymantria dispar. Studies on the regulation of pheromone biosynthesis and release were carried out simultaneously in some species in Korea, resulting in the characterization of PBAN (pheromone biosynthesis activating neuropeptide) in H. assulta and Adoxophyes sp. A semiochemical research system has been firmly established in Korea through these studies. In some areas, successful monitoring and mating disruption technology have been effectively transferred from researchers to the end users in Korea, which will soon be expanded to wider areas. Continuous attempts to identify and use semiochemicals as well as wider applications of semiochemicals in pest control are expected in Korea in the coming years. Since Korean research on semiochemicals does not cover vast areas due to limited resources, focused research and practical application will be needed for selected target insect species.
