Spotted wing drosophila, Drosophila suzukii, causes damage on several fruits include strawberry in Korea. D. suzukii lays egg inside fruit surface, and this behavior makes D. suzukii hard to detect, so many countries designated D. suzukii as a quarantine pest. Recently, Australian government demand methyl bromide fumigation on Korean export strawberry to prevent D. suzukii invasion. In this study, we tested methyl bromide to control D. suzukii, and also tested separate and concurrent treatments of methyl bromide to evaluate phytotoxicity on strawberry. When 40 g/m3 of methyl bromide was treated for 3 hours, all stages of D. suzukii were completely controlled. When treated separate and concurrent with cold temperature treatments of methyl bromide, there’s no specific phytotoxicity on strawberry. This result indicates that separate and concurrent treatments of methyl bromide do not cause phytotoxic effect on strawberry and methyl bromide is effective to control D. suzukii.

The effect of fumigation on the phosphine-susceptible and -resistant strains in the T. castaneum was evaluated using phosphine, ethyl formate, and combination with phosphine and ethyl formate (phosphine+ethyl formate). The Lethal Concentration Time (LCT)50 analysis of susceptible strains, late larva showed that phosphine (0.13 mg·h / L), ethyl formate (80.91 mg·h / L), and phosphine + ethyl formate (19.36 mg·h / L). The LCT50 of adult was 0.05 mg·h / L, 68.58 mg·h / L and 17.84 mg·h / L when treated with phosphine, ethyl formate, and phosphine + ethyl formate. The LCT50 of resistant strains, late larva was found to 33.32 mg·h / L of phosphine, 113.46 mg·h / L of ethyl formate and 129.85 mg·h / L of phosphine + ethyl formate, and the LCT50 of adult was 55.71 mg·h / L of phosphine, 85.39 mg·h / L, phosphine + ethyl formate 85.83 mg·h / L. The treatment of three fumigants (phosphine, ehtyl formate, and phosphine+ethyl formate) showed the possibility of controlling against T. castaneum of phosphine-susceptible and –resistant strains.

 ,  , Two pupillarial species, Cryptoparlatorea leucaspis Lindinger and Fiorinia japonica Kuwana, are recorded for the first time in Korea. Both species were found on coniferous trees, Cryptomeria japonica and Torreya nucifera. Also an identification key, brief diagnoses, and photographs of Korean pupillarial species are provided to assist in their identification.

Two species of the genus Andaspis, Andaspis crawii (Cockerell) and Andaspis kashicola (Takahashi) are newly recorded in the Korean fauna of armored scales (Diaspididae). A key to species of Andaspis, illustrative photographs and information on the distribution and hosts of each species, are also provided to identify the specimens of Andaspis collected in Korea.

Aleuroclava aucubae (Kuwana) and Aleuroclava euryae (Kuwana) are newly recorded in the Korean fauna of whiteflies (Aleyrodidae). A key to species of Aleuroclava is also provided with illustrative photographs.
