Abstract The fall armyworm, Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), is a polyphagous pest native to the tropical and subtropical Americas, but it has recently invaded Eastern Hemisphere spread rapidly. This migratory moth, which can fly long distances, now poses global threat as transboundary pest. To establish an efficient management program against this pest, monitoring of its occurrence essential. Lures impregnated with four synthetic pheromone components S . – ( Z...
Abstract An eradication project against the sweetpotato weevil, Cylas formicarius ( Fabricius) (Coleoptera: Brentidae), one of most important pests sweet potato in world, was initiated Oct. 2007 on Tsuken Island, Okinawa Prefecture, Japan. The sterile insect technique (SIT) and male annihilation (MAT) were employed as main control measures to suppress ultimately eradicate wild populations by impeding normal mating. In addition, two monitoring methods (host plant survey trap survey) used...
Scirtothrips dorsalis Hood is one of the most important pest thrips on mango Mangifera indica L., trees cultivated in Okinawa Prefecture, southwestern Japan. has two strains, C and YT, but there little information about their geographical distribution composition ratio Prefecture. In this study, we collected S. infesting young leaves from islands Prefecture analyzed strain based a multiplex-PCR method. Among 80 localities investigated number with only C, both strains or YT were 68 locations,...
Abstract Spodoptera frugiperda , an invasive pest insect that targets maize and other crops, first arrived in Japan the summer of 2019. This species occurs year‐round East Asian subtropical regions such as southern mainland China island Taiwan, where mean air temperature coldest month is above 10°C. Adults are similarly found throughout year on southwestern islands Japan. Trap monitoring there showed continuous or intermittent S. catches three winter seasons since However, it was difficult...
