Dysmicoccus brevipes (Cockerell) and Dysmicoccus neobrevipes Beardsley are major pests of pineapples, ornamentals, and vegetable crops in many countries around the world. The potential distribution of these mealybug pests into South Korea remains a prime concern because of their high incidence in interceptions screened during inspection. Hence, these species prompted a modelling effort to assess their potential risk of introduction. Potential risk maps were developed for these pests with the CLIMEX model based on occurrence records under environmental data. The potential distribution of these pests in South Korea in the 2020s, 2050s and 2090s is projected based on the RCP 8.5 climate change scenario. Results show that D. brevipes and D. neobrevipes have little potential for invasion in the exterior environment of South Korea due to high cold stress. However, for D. brevipes, three locations in Jejudo were predicted to be marginally suitable for this pest under future climate factors. In that respect, the results of these model predictions could be used to prepare a risk-based surveying program that improves the probability of detecting early D. brevipes and D. neobrevipes populations.

The scale insects (Hemiptera: Coccomorpha) are one of the most successful groups of plant-feeding arthropods. Most species of shade trees, fruit trees and ornamental shrubs are subject to scale insect attacks. Based on the review of the literature and survey results, the host plant list of the scale insects in South Korea was developed and updated. Herein, an updated list of 253 species of host plants in 71 families associated with scale insects is provided and 162 species in 15 scale insect families are listed.
A preliminary catalogue of the moths (Lepidoptera except Papilionoidea) of Tobago, West Indies
(2017)
This catalogue comprises records of 355 species of moths (non-papilionoid Lepidoptera) from Tobago, of which 15 are partially identified. Of this total, all except 17 (5%) are known from Trinidad, although not all these records from Trinidad are published yet. Of these 17, eleven are expected to occur in Trinidad as they also occur on the mainland of South America and two are only known from Tobago but will probably also occur in Trinidad. This leaves just four species (1% of the total) that are known from the Lesser Antilles and are currently not known from further south than Tobago. The families represented by the most species are Erebidae, Crambidae, Geometridae, Noctuidae and Sphingidae, which between them account for 73% of records. Taxonomic changes are made as follows. Podalia farmbri (Kaye, 1925) sp. rev. (Megalopygidae) is removed from the synonymy of P. nigrescens Schaus, 1905. Podalia walkeri Hopp, 1935 and P. dimidiata (Walker, 1865) are syn. nov. of P. farmbri Kaye, 1925. Renia bipunctata (Kaye, 1901) (Erebidae) is a comb. nov. for Zanclognatha bipunctata. Aristaria trinitalis Schaus, 1906 (Erebidae) is a syn. nov. of Renia bipunctata Kaye, 1901. Aglaonice deldonalis Walker, 1859 sp. rev. (Erebidae) is removed from the synonymy of A. hirtipalpis Walker, [1859]. Plusiodonta cupristria Kaye, 1923 (Erebidae) is a syn. nov. of Oraesia excitans Walker [1858]. Oroscopa abluta (Schaus, 1912) (Erebidae) is a comb. nov. for Freilla abluta Schaus, 1912, which is a new combination in common use, but not previously published. Ptichodis dorsalis (Fabricius, 1797) (Erebidae) is a comb. nov. for Noctua auct. dorsalis Fabricius, a new combination already in use, but not formally published. I endorse the unpublished conclusion of I.W.B. Nye that Ptichodis basilans (Guenée, 1852) is a syn. nov. of Ptichodis dorsalis (Fabricius, 1797). Ptichodis agrapta Hampson, 1913 is also a syn. nov. of Ptichodis dorsalis (Fabricius, 1797).
