Sex pheromone production in most moths is initiated following pheromone biosynthesis activating neuropeptide receptor (PBANR) activation. PBANR was initially cloned from pheromone glands (PGs) of Helicoverpa zea and Bombyx mori. The B. mori PBANR is characterized by a relatively long C-terminus that is essential for ligand-induced internalization, whereas(More)
PCR is a useful technique to detect mutations in insecticide resistance genes or to analyze gene flow in pest insects. Plutella xylostella (L.) is one of the most important pests that develops insecticide resistance, and it is desirable to make efficient use of specimens obtained from pheromone-baited sticky traps. To estimate the period of DNA preservation(More)
Banker-plant systems with Aphidius species have been used to control pest aphids in greenhouses in Japan. However, the occurrence of secondary parasitoids, which lead to aphid-control failures, and of minor aphid species, are problematic. In this work the ecological characteristics of Ephedrus nacheri Quilis (Hymenoptera: Braconidae), an alternative(More)
Japan has only three registered baculovirus biopesticides despite its long history of studies on insect viruses. High production cost is one of the main hindrances for practical use of baculoviruses. Enhancement of insecticidal effect is one possible way to overcome this problem, so there have been many attempts to develop additives for baculoviruses. We(More)
