Biological control as a tactic of environmentally safer agriculture has not been widely accepted by farmers. In Japan integrated biological control with native natural enemies is rapidly developing for greenhouse vegetables, because of high prices of commercially mass-reared biological control agents. We have studied the effective use of natural enemies at farm level, focusing on generalist predators, although there are differences in using natural enemies for augmentation in greenhouses and conservation in open fields. Recently, however, insectary plants (crops) have been considered as a key component for enhancing natural enemies. We have examined the effectiveness of candidate insectary plants on natural enemies and implemented biointensive IPM with insectary plants at farm-level. Our recent study suggested that some herbs and crops are highly effective on improving the survival and reproduction of generalist predators. By growing such plants in vegetable greenhouses and open-fields, natural enemy populations could be enhanced and thus stably persist even after targeted prey populations are exploited. Moreover, insectary plants may result in a shift of IPM from level I to level II.

Background/Aims: Diffuse or segmental irregular narrowing of the main pancreatic duct (MPD), as observed by endoscopic retrograde cholangiopancreatography (ERCP), is a characteristic feature of autoimmune pancreatitis (AIP). Methods: ERCP findings were retrospectively examined in 40 patients with AIP in whom irregular narrowing of the MPD was detected near the orifice. The MPD opening sign was defined as the MPD within 1.5 cm from the orifice being maintained. The distal common bile duct (CBD) sign was defined as the distal CBD within 1.5 cm from the orifice being maintained. Endoscopic findings of a swollen major papilla and histological findings of specimens obtained from the major papilla were examined in 26 and 21 patients, respectively. Results: The MPD opening sign was detected in 26 of the 40 patients (65%). The distal CBD sign was detected in 25 of the 32 patients (78%), which showed stenosis of the lower bile duct. The patients who showed the MPD opening sign frequently showed the distal CBD sign (p=0.018). Lymphoplasmacytic infiltration, but not dense fibrosis, was histologically detected in biopsy specimens obtained from the major papilla. Conclusions: On ERCP, the MPD and CBD adjacent to the major papilla are frequently maintained in patients with AIP involving the pancreatic head. These signs are useful for diagnosing AIP on ERCP.
