Objective: To report three consecutive cases of ophthalmia nodosa due to caterpillar hair (setae). Methods: This is a brief report. Results: Three cases of ocular surface injury with history of contact with caterpillar setae are reported. The first case is that of a child with right upper lid swelling, papillary conjunctivitis, and setae embedded in the upper palpebral conjunctiva causing multiple distinct linear abrasions on the cornea. The second patient was an adult male who had setae embedded in the corneal stroma, palpebral conjunctiva, and bulbar conjunctiva, resulting in corneal epithelial defect and a conjunctival granuloma. The last was an adult male who had a subconjunctival hemorrhage due to setae penetration. All were managed with setae removal, topical antibiotic and steroid eyedrops, and other symptomatic treatment strategies as needed. Conclusion Clinical features of ophthalmia nodosa vary depending on the site of setae penetration. Meticulous setae removal is key to successful management in addition to inflammation control and infection prophylaxis.

During a survey of fungal species in South Korea, a species of Volutella ciliata was isolated and described based on the analysis of the internal transcribed spacer region of its rDNA and its morphological characteristics. This is the first record of Volutella ciliata isolated from crop field soil in Korea.

By light and scanning electron microscopy, the morphologies of Korean pubic louse(Phthirus pubis) were described and measured. Especially, electron microscopic structures of palpus, tuft organ, sensilla basiconicum and palpal lobe were reviewed in detail. The variations were obserbed in the number of dorsal setae and the setae of membranous processes of abdomen. And also, the importance of public health and epidemiological aspects was discussed.

Heortia vitessoides is the most serious pest of Aquilaria sinensis,which is an economically important evergreen tree native to China and is the principal source of Chinese agarwood. In severe infestations,the insects completely eat up the leaves of A. sinensis,causing severe economic losses. In a more recent study,we found that the antennal sensilla of adult play important roles in the host location,mating and oviposition of H. vitessoides. Here,the external morphology of the antennal sensilla of H. vitessoides were examined using scanning electron microscopy. The result showed that the antennae of both sexes of H. vitessoides were filiform in shape,which consist of the scape,pedicel and about 64 segments of flagellomeres. Eight morphological sensilla types were recorded in both sexes,including sensilla trichodea,sensilla chaetica,sensilla basiconica,sensilla coeloconica,sensilla styloconica,sensilla auricillica,sensilla squamiformia and böhm bristle. Major differences were recorded in the distribution and quantity of different sensilla types in each segment of antenna. The sensillas are almost confined to the ventral and lateral surfaces rather than the back side of antennae. Antennal flagella contained the most sensilla while the scape and pedicel segments only contained böhm bristles and sensilla squamiformias. Sensilla trichodea Ⅲ were only found on male antennae. These results are discussed in relation to the possible roles of the sensilla types in the host location,mating and oviposition selection behavior of H. vitessoides.
