DOI : 10.5656/KSAE.2012.12.0.078
The moving period and overwinteing site of Scrobipalpa salinella (Zeller) were investigated in Gimje, Jeonbuk, and Shinan, Jeonnam in the glasswort field. Densities of Scrobipalpa salinella larvae were started to increase from mid-September in halophytes, such as Suaeda asparagoides, S. japonica, and S. maritima, rather than glasswort. S. salinella was overwintering inside the halophytes in old larva. Density ratio of overwintering S. salinella in Suaeda asparagoides, S. japonica, and S. maritima were 20.5, 28.4 and 51.1%, respectively. Overwintering population was highest in S. maritima among halophytes. The occurrence of first adult in the next spring was from April 19 to April 20 in Gimje, Jeonbuk, and Shinan, Jeonnam.

Choi, Moon Bo ; Kim, Jeong Kyu ; Lee, Jong Wook ;
Korean journal of applied entomology, volume 52, issue 2, 2013, Pages 85~91
DOI : 10.5656/KSAE.2013.02.1.072
A diverse range of taxonomic confusions are brought forth since past taxonomic information including major errors following its initial provision of some uncertain information has repeatedly been applied to Korean Vespidae in its identification. Thus, this study, which made a final summarization of research on Vespidae, provided the list of Korean Vespidae determined except for Eumeninae, with their distributional data. A total of 30 species (including 3 subspecies) belonging to 5 genera of 2 subfamilies are listed: subfamily Vespinae (3 genera/ 18 species) and subfamily Polistinae (2 genera/ 12 species).

Kim, Dong Eon ; Kil, Jihyon ; Lee, Do Hun ;
Korean journal of applied entomology, volume 52, issue 2, 2013, Pages 93~100
DOI : 10.5656/KSAE.2013.02.0.004
In this study, the distribution of Cantao ocellatus in Korea occurred at Jindo, Tongyoung, Gwangju and Taean including Jejudo in 2012 and was coincidentally in accordance with the distribution of Mallotus japonicus as a host plant. The adult emerges in M. japonicus occur from late June to early July and can be observed until the end of October. The investigation of the female and male was measured, developmental characteristics, host plant and oviposition preference under the conditions of temperature
, humidity 65%(
), day length 16L:8D, by indoor breeding. For females and males respectively, average body lengths were 26.20 mm and 23.88 mm, body widths 11.35 mm and 10.57 mm, head widths 3.84 mm and 3.64 mm, probosics lengths 7.90 mm and 7.27 mm, antennal lengths 9.87 mm and 9.69 mm, anterior leg lengths 12.50 mm and 12.27 mm, intermediate leg lengths 14.61 mm and 13.12 mm, posterior leg lengths 16.90 mm and 16.53 mm, and fresh weights 0.46 g and 0.31 g. It was seen that two kinds of C. ocellatus had prickles at the end of the pronotum which had developed in the fifth instars. The female is distinguished from the male by the reproductive organ and the spotted pattern on the abdominal segment. The preference of drinks was fruit, leafstalk, midrib, and branch in Mallotus japonicus (Thunb.) Muell. Arg., Mallotus japonicus `Variegatus`, Ricinus communis L., Lonicera japonicus var. repens (Siebold) Rehder, Citrus sinensis (L.) Osbeck and Zelkova serrata (Thunb.) Makino.

DOI : 10.5656/KSAE.2013.03.0.012
A greenhouse soil infested with an obligate nematode parasitic bacterium, Pasteuria penetrans, was used to test the effect of temperatures on the endospore attachment to root-knot nematode, Meloidogyne arenaria, juveniles (J2). Freshly hatched J2s were inoculated to the soil in petri dish and incubated under different temperatures of
for 7 days. The endospore attachment rates were 100% in all the temperatures, while the number of endospores attached per J2 was highest in
with 28.3 endospores/J2 followed by 20.2, 18.6, and 13.6 in
, respectively. When the soil was pre-treated under different temperatures before the J2 inoculation, the endospore attachment rates significantly decreased from 60% in room temperature to
, 31.7, 8.3, 5.0, and 0% after the soil incubation in
for 10 days, respectively. The endospore numbers attached per J2 were 3.5, 4.3, 1, 1, and 0 when the soil was pre-treated in
, respectively, which were lower than 5.3/J2 of room temperature treated soil. The P. penetrans isolate in the soil showed nematode species-specific endospore attachment characteristics with 100% attachment rate only on M. arenaria J2s while the rates were 0% on M. hapla and M. incognita J2s.

A microbial insecticide "Bt-Plus" has been developed to enhance an insecticidal efficacy of an entomopathogenic bacterium, Bacillus thuringiensis (Bt). However, its wettable powder formulation is not preferred by farmers and industry producers due to relatively high cost. This study aimed to develop a soluble concentrate formulation of Bt-Plus. To this end, an optimal mixture ratio of two bacterial culture broths was determined to be 5:4 (v/v) of Bt and Xenorhabdus nematophila (Xn) along with 10% ethanol preservative. In addition, Bt broth was concentrated by 10 times to apply the mixture at 1,000 times fold dilution. The resulting liquid formulation was sprayed on cabbage crop field infested by late instar larvae of the diamondback moth, Plutella xylostella. The field assay showed about 77% control efficacy at 7 days after treatment, which was comparable to those of current commercial biopesticides targeting P. xylostella. For storage test in both low and room temperatures, the liquid formation showed a relatively stable control efficacy at least for a month. To develop a quality control technique to exhibit a stable control efficacy of Bt-Plus, Bt spore density (
spores/mL) and eight active component concentrations of Xn bacterial metabolites in the formulation products have been proposed in this study.

Park, Chang-Gyu ; Kim, Kwang-Ho ; Park, Hong-Hyun ; Lee, Sang-Guei ;
Korean journal of applied entomology, volume 52, issue 2, 2013, Pages 133~140
DOI : 10.5656/KSAE.2013.02.1.070
The developmental times of the immature stages of Sogatella furcifera (Horvath) were investigated at ten constant temperatures (12.5, 15, 17.5, 20, 22.5, 25, 27.5, 30, 32.5,
), 20~30% RH, and a photoperiod of 14:10 (L:D) h. Eggs were successfully developed on each tested temperature regimes except
and its developmental time was longest at
(22.5 days) and shortest at
(5.5 days). Nymphs successfully developed to the adult stage from
temperature regimes. Developmental time was longest at
(51.9 days) and it was decreased with increasing temperature up to
(9.0 days). The relationships between developmental rate and temperature were fitted by a linear model and seven nonlinear models (Analytis, Briere 1, 2, Lactin 2, Logan 6, Performance and modified Sharpe & DeMichele). The lower threshold temperature of egg and total nymphal stage was
respectively. The thermal constant required to complete egg and nymphal stage were 122.0 and 156.3 DD, respectively. The Briere 1 model was best fitted (
