Characteristics of development and life cycle of the stick insect (Baculum elongatus) were studied through the laboratory experiments at 16, 20, 24. 28, 32℃ of different constant temperatures and the field study in the American Iocust forest in the Geomo mountain in Gumi of Gyongsangbuk-do. The stick insect showed five developmental stages for a nymph. The adult stage consisted of two periods : preoviposition and oviposition. During the former period, a time to mature eggs in ovary, the body length of the stick insect adult increased. The developmental periods of the young nymph were 97.3 days at 16℃, 65 days at 25℃, 49.7 days at 24t℃, and 42.8 days at 28℃, displaying higher growth rate at higher temperatures. All the test insects were died before the 3rd nymph stage at 32℃ of temperature. The lower growth- limit temperature and the effective accumulated temperature above the limit temperature required to complete nymph stages were 6.6℃ and 909 degree days, respectively. The duration of adult Period increased according to the increase of experimental temperatures. The optimum temperature for the oviposition was around 24℃, and it was coincident with the mean temperature of Gumi, where the field study was carried out, in July and August considered as the oviposition period in the field. The developmental stages of the stick insects were seasonally determined an the population of the Geomo mountain in Gumi. using the body length of the stick insects. Based on these results, a suitable time to control the stick insects in the their outbreaking arena was considered before mid June.

Stick insect has several peculiarities like parthenogenesis, unique external features and dropping oviposition, so it is very hopeful to use for industrial insect. The oviposition was established by only female without fertilization with sperm of male which was not discovered during this study. The oviposition period was 37.3±14.9 days and the number of eggs per female was 41.5±16.5 eggs. The hatchability was 73.3% at 25℃and 66.7% after low temperature treatment(8℃, 60 days). The developmental periods and the length of egg were 100.9±4.2 days and 0.33±0.0cm, respectively, and the adult's life span was 49.7±16.0days. Differently other research which reported five nymph stage, the developmental stages of nymph showed five(62.9%) or six(37.1%) stages. The duration and the length of nymph increased according to the increase of nymph stage. Stick insect preferred the leaf of American locust, White oak, Chestnut, Bush clover in order but could be reared with food of the leaf of all these trees. Stick insects are herbivorus but made an attack each other when encountered in the small space. For sustaining mass rearing of stick insect, it is needed that the development of artificial diet and high density rearing method.

Baculum elongatum has several peculiarities such as parthenogenesis, unique external features, changing body color, and dropping oviposition, which makes it a potential economically useful insect. Oviposition was performed by females without fertilization by the sperm of males. The oviposition period was 42.2 ± 22.7 days and the number of eggs per female was 109.5 ± 70.5 eggs. The hatch rate was 73.3% at 25°C and 66.7% after low temperature treatment (8°C for 60 days). In nature, B. elongatum overwinters as an egg, but it can be assumed from the results that cold temperatures were not required for hatching. The hatch rate was 98.2% in the treatment using floral foam, fermented sawdust, and leaves. The developmental period was 100.9 ± 4.2 days for eggs, 55.3 ± 4.6 days for nymphs, and 49.7 ± 16.0 days for adults. The length of the eggs was 0.33 ± 0.0 cm and the lengths of the nymphs were clearly distinguishable according to the instar stage. Clover(Trifolium repens) was an excellent diet as it was similar to the host plant and could be used as an alternative diet. The rate of reaching adulthood for the insects was 66.7% on an artificial diet containing 25% acacia leaves. For sustainable mass rearing of nymphs or adults of B. elongatum, a natural diet could be used such as acacia (Robinia pseudoacacia), white oak (Quercus aliena), chestnut (Castanea crenata var. dulcis), and bush clover (Lespedeza bicolor), or an alternative diet such as clover or artificial diet.

Baculum elongatum has a long, thin shape that resembles a twig, propagates by parthenogenesis, changes body color, and drops eggs, all of which suggests its potential in the commercial market, especially as an educational pet insect. This study was carried out to determine the best hatching environment and an alternative or artificial diet for rearing B. elongatum to be developed as a commercial and educational pet insect. Oviposition was performed by females without fertilization by the sperm of males. The oviposition period was 42.2 ± 22.7 days and the number of eggs per female was 109.5 ± 70.5 eggs. The hatch rate was 73.3% at 25°C and 66.7% after low temperature treatment (8°C for 60 days).

To rear nymphs and adults of B. elongatum, natural diet such as acacia, white oak, chestnut, or bush clover leaves, or an alternative diet such as clover or an artificial diet can be used.

본 보고는 2020년 산림 지역에서 대발생하여 큰 피해를 준 매미나방과 대벌레에 의한 피해면적과 피해수종에 대해 기술하였다. 매미나방에 의한 식엽 피해는 강원(1,638 ha), 경기(1,134 ha), 충북(726 ha), 서울(476 ha) 등 중부지방을 중심으로 심각하였다. 대벌레는 서울시 은평구와 고양시 덕양구 사이에 위치한 봉산(약 19 ha)에서 대발생하였다. This report describes the damage caused by gypsy moths (Lymantria dispar) and stick bugs (Ramulus mikado) to forests and host plants in 2020. Severe tree-crown defoliation was found in central parts of Korea, especially Gangwon (1,638 ha), Gyeonggi (1,134 ha), Chungbuk (726 ha) and Seoul (476 ha). Stick bug outbreaks occurred in hilly areas, such as Mt. Bongsan, located between Seoul and Goyang.
