2019년 경남 진주시 배나무에서 석류가루이(신칭) Siphoninus phillyreae (Haliday, 1835) 가 발견되었다. 분포조사를 통하여, 부산, 창원, 진주, 광양, 순천, 고흥, 고성에서 발생을 확인하였고, 기주식물로 석류, 배, 모과, 매실, 산사, 비파, 홍가시, 피라칸타, 배롱나무, 꽃사과나무를 확인하였다. 이 해충의 피해 상황과 분류학적 특징을 기재한다. In 2019, the ash whitefly, Siphoninus phillyreae (Haliday, 1835), was firstly found on a pear tree in Jinju-si, Gyeongsangnam-do. From occurrence survey, we confirmed that S. phillyreae was occurred in seven cities, Busan, Changwon, Jinju, Gwangyang, Suncheon, Goheung, and Goseong. In addition, seven plants, such as Punica granatum, Pyrus pyrifolia, Cydonia oblonga, Prunus mume, Crataegus pinnatifida, Eriobotrya japonica, Photinia glabra, Pyracantha angustifolia, Lagerstroemia indica, and Malus prunifolia, were detected as hostplants. In this study, we present the first report of this species in Korea and describe the damage caused by S. phillyrease and its taxonomic information.

The occurrence of the crown and root rot on strawberry (Fragaria×ananassa Duch.) has been reported in greenhouses in Sancheong and Hamyang, Gyeongnam province, Korea in June, 2019. The infected plants showed browning rot of the inner crown and root, causing delayed development, lack of growth, and poor rooting. The browning rot of the inner crown and root can sometimes lead to wilting and collapsing of plants. Fungi were isolated from the symptomatic root and crown. Based on the results of morphological and phylogenetic analyses, the causal agent of the disease was identified to be Neopestalotiopsis clavispora. The fungal isolates were then used for inoculation into strawberry plants to determine the causal agent of the crown and root rot as per Koch's postulates. The inoculated strawberry plants showed the same symptoms as the originally infected plants, and the fungal pathogen re-isolated from the lesions showed the same morphological characteristics as the original pathogen. This is the first report on the occurrence of crown and root rot on strawberry (Fragaria×ananassa Duch.) caused by N. clavispora in Korea.
