    菌床シイタケ栽培の害虫であるナガマドキノコバエの幼虫の，シイタケ菌床を用いた効率的な飼育方法を開発した．雌雄成虫1ペアをシイタケの柄と蒸留水で湿らせたろ紙片とともにポリ袋に入れた．シイタケの柄やろ紙片に産下された卵をピンセットを用いて別のろ紙片に乗せてから，培養袋から取り出した菌床の上に置いた．幼虫は，菌床および子実体を食べて発育し，菌床表面で蛹化した．除袋直後の菌床を用いたり，菌床上に発生した子実体を残しておくと，羽化率が高く，発育期間が短く，大きな蛹が得られた．日長をLD16:8またはLD10:14，温度を12，15，20，23または25℃にして，卵から成虫として羽化するまで飼育した．卵から羽化までの発育期間は，温度が高いほど短くなった．卵から羽化までの期間の発育零点と有効積算温量は，LD16:8で飼育した雄と雌では，それぞれ7.2℃と293.6日，7.3℃と304.3日度であり，LD10:14で飼育した雄と雌では，それぞれ7.0℃と280.5日度，7.1℃と293.6日度であった．

    The effect of pesticides on the Nauru biotype, a common biotype of Bemisia tabaci in the Ryukyu Islands, was compared with that on the B biotype under laboratory conditions. Twenty-four commercial agrochemicals were tested on adults, third instar larvae, and eggs. Overall, the majority of the pesticides tested were effective (>70% mortality) for Nauru, but not for the B biotype. Fourteen insecticides were effective for all stages of the Nauru biotype, while only two (pyridaben and emamectine benzoate) were effective for all stages of the B biotype. The effects of synthetic pyrethroid, imidacloprid, and some acaricides were clearly greater in the Nauru biotype than in the B biotype. The results suggest that the Nauru biotype is a less important pest than the B biotype because of the greater susceptibility to insecticides of the former.

    Nutritional status of post-overwintering adults of Halyomorpha halys at their hibernating site was investigated in Akita Prefecture, northern Japan from 2000 to 2005. Nutritional levels of the adults were significantly lower than those of pre-hibernating adults, and the fat body did not develop. Additionally, nutritional levels of the adults recently exited from the hibernating site were significantly lower than those of the adults at their hibernating site in April in 2001 and 2002. Almost all the adults given only water in field from late April could not survive until late May in 2002. These observations suggested that post-overwintering adults of H. halys exiting from the hibernating sites cannot survive for a long period, if they cannot feed on their suitable food plant.

    To understand the biological functions of male-produced pheromone of Nezara antennata Scott, we investigated the physiological status of N. antennata attracted to conspecific adult males. Most females captured in traps baited with adult males had immature ovaries and were unmated. Males attracted in July had entirely undeveloped ectodermal accessory gland, which are involved in reproduction. Many adults were attracted from June to July, when the bugs were considered to be in summer diapause. It is suggested that N. antennata use the volatiles emitted by adult males for reasons other than as mating cues. The nutritional status of most N. antennata adults captured in traps was poor. These results suggested that N. antennata use the volatiles emitted by adult males as cues to find food.

    The diel activity pattern of Neoempheria ferruginea, a harmful fungus fly in the sawdust-based cultivation of shiitake, Lentinula edodes, was studied at 20°C under a photoperiodic regime consisting of a 16-h photophase and an 8-h scotophase. Adult eclosion occurred at photophase in 93% of males and 95% of females. Adult activities showed two peaks: one around when the light was turned off and the other soon after the light was turned on. Copulation occurred mainly around when the light was turned off (40%)or on (40%). These results suggest that the adults are active mainly at dusk and dawn under natural conditions. The duration of copulation was 16.6±7.7 h (mean±SD).

    The bean webworm, Pleuroptya ruralis (Scopoli), is known as a serious pest of soybeans. The overwintering generation and summer generation use the nettles (Urticales, Urticaceae) and soybeans as host plants, respectively. Parasitoids of P. ruralis larvae were investigated in nettle colonies and soybean fields in 2009 and 2010. Eleven species of parasitoids that belong to Braconidae, Ichneumonidae and Bethylidae emerged from the P. ruralis. Percentage parasitism in overwintering generation is higher than that in summer generation. The predominant parasitoid in overwintering generation was Macrocentrus cingulum Brischke in Braconidae .
