DOI : 10.5656/KSAE.2010.49.1.011
Measurements were made on morphology of each developmental stages of the chestnut weevil, Curculio sikkimensis, reared in the laboratory and field from 2003 to 2006. The size of egg was 0.8
0.03 mm. The escaping larvae were measured, in average, as 98 mg in body weight, 10.65 and 3.99 mm in body length and width, and 1.70 mm in head width. Pupal size of female and male was 7.01 and 6.53 mm, respectively. The fresh weight (0.343 g), body length (7.76 mm) and width (3.38 mm), and head width (1.60 mm) of female adults were significantly bigger than those (0.268 g, 7.14 mm, 3.01 mm and 1.37 mm, respectively) of male adults. Proboscis length (6.53 mm) and antennal length (5.47 mm) of female was also significantly longer than those (3.56 and 4.63 mm, respectively) of male. The larvae of C. sikkimensis overwintered for 1~3 years and their body weight, body length, and body width were decreased. The ratio between proboscis length and body length, the basipodite position attached to the proboscis, and shape of the sex organ on the abdominal end could be used to discriminate sexes.

Park, Ji-Doo ; Park, Il-Kwon ;
Korean journal of applied entomology, volume 49, issue 1, 2010, Pages 17~22
DOI : 10.5656/KSAE.2010.49.1.017
Pachynematus itoi Okutani emerges three times a year, and overwinters as a pre-pupa in cocoon. First emergence of P. itoi was from 7th May to third June. Second and third emergence was from 20th June to 13th July and fourth to 25th August, respectively. Mean oviposited egg number was 59, and egg period was about 9 days. Hatching rate was >90%. Oviposited egg number was the highest in the first needle cluster of short shoot followed by second and third. P. itoi did not oviposit on single needle (long shoot) of Larix leptolepis (Sieb. et Zucc.). Larva had five instars, and larval period was about 20 days. Larva prefer needle cluster of short shoot to single needle of long shoot. Mature larva descended from host tree and pre-pupa in cocoon overwinter at topsoil.

Yi, Hoon-Bok ; Kim, Hyun-Jung ;
Korean journal of applied entomology, volume 49, issue 1, 2010, Pages 23~29
DOI : 10.5656/KSAE.2010.49.1.023
The environmental risks of cucumber mosaic virus resistant transgenic chili peppers with the CMVP0-CP gene on non-target organisms in the agroecosystem environments was evaluated during the periods of the chili pepper growing season (June 19, July 30, August 31) in 2007. Arthropods assemblages leaves and flowers of chili peppers were quantitatively collected by using an insect vacuum collector to compare the arthropod community structures between non-transgenic chili peppers (nTR, P 915) and mosaic virus resistant transgenic chili peppers (TR, CMV-cp, line 7). There was no statistical difference in the arthropod community structure between the two types of crops, nTR and TR, at the same season, although the species richness and Shannon's index were somewhat different among seasons; indicating no effects of genetically modified peppers on the arthropod community. However, further studies were required to conclude more concretely for the potential environmental risk of the transgenic chili pepper of CMV-cp.
Enhanced Mating Disruption of the Oriental Fruit Moth, Grapholita molesta (Busck), Using Pheromone Edge Treatment Along with Food Trap

DOI : 10.5656/KSAE.2010.49.1.031
Mating disruption (MD) using synthetic sex pheromone lures has been used to control the Oriental fruit moth, Grapholita molesta (Busck), in apple orchards. In Korea, where several small apple orchards are clustered but independently managed, its efficacy has been suspected mainly due to immigration of any mated females from nearby untreated cultivating areas. This study developed an edge treatment technique to decrease any local MD-free zones in a specific MD-treated farm and to trap any immigrating mated females by installing MD lures and food traps around the apple farm with 10 meter intervals. The addition of the edge treatment to the MD significantly prevented leaf and fruit damages induced by G. molesta compared to MD only. Moreover, this study tried to optimize the MD control technique by determining frequency of MD application. It suggests two MD applications with the edge treatment at the end of March and at the early of July to be effective throughout the entire apple growing seasons.
Applicability of CATIS as a Postharvest Phytosanitation Technology against the Peach Fruit Moth, Carposina sasakii Matsumura
Son, Ye-Rim ; Choi, Kyung-Hee ; Kim, Yong ; Kim, Yong-Gyun ;

DOI : 10.5656/KSAE.2010.49.1.037
As an environment-friendly phytosanitary measure, CATTS (controlled atmosphere temperature treatment system) has been developed to kill several quarantine insect pests infesting subtropical agricultural commodities. This study tested any possibility to apply CATTS to apples to effectively eliminate the peach fruit moth, Carposina sasakii, which has been regarded as a quarantine insect from the imported countries. When the larvae of C. sasakii were directly exposed to
(an installed lethal temperature of CATTS), they showed a median lethal time at 14.66 min. Addition of high carbon dioxide to the temperature treatment enhanced the thermal limit susceptibility of C. sasakii to
. CATTS device was constructed to automatically control
concentration and temperature with real-time monitoring both in the chamber and in the fruit. The larvae internally infesting apples were tested using the CATTS device and showed 100% lethality after 60 min exposure to a treatment of
in the chamber. Relatively long exposure may be due to the deviation between the ramping temperature (
/min) of the chamber and the ramping temperature (0.12-
/min) inside apple fruit, where the tested larvae were located. This study suggests a possibility that CATTS can be applied as a quarantine measure to kill the larvae of C. sasakii locating inside the apples.

DOI : 10.5656/KSAE.2010.49.1.043
This study was conducted to investigate optimal conditions for formation of synnemata from Beauveria bassiana. The strain of B. bassiana was isolated from a host of Oncotympana fuscata in Halla mountain of Jeju island. The yield of synnemata was the highest at application of brown rice (90%) and silkworm pupae (10%) media. On the other hand, the other media did not result in formation of synnemata. The highest formation of synnemata was achieved at conditions of moderate air inflow and
. The optimal moisture and light intensity for formation of synnemata were 60% and 300 lux, respectively. In addition, inoculation of the liquid spawn resulted in higher yield than that of asexual spore.

Bumblebees are widely used to pollinate crops in greenhouses and fields. Here we firstly developed an apparatus for the oviposition induction of the bumblebee Bombus ignitus using electricity. The apparatus consists of boxes for colony initiation, part of temperature control, part of heat transfer, and moving shelf. The result shows that the rates of oviposition and colony foundation in the newly developed apparatus are respectively 3.9% and 5.2% higher than in the existing apparatus using hot water. More importantly, the newly developed apparatus is 75% cheaper in costs and can more save energy than existing apparatus. These results indicate that the newly developed apparatus could serve as an effective apparatus for the oviposition induction of B. ignitus.

Korean journal of applied entomology, volume 49, issue 1, 2010, Pages 61~67
DOI : 10.5656/KSAE.2010.49.1.061
Effect of inoculation level on pathogenicity, development, and propagation of entomopathogenic nematode, Steinernema arenarium was investigated using the last instar of great wax moth, Galleria mellonella. Pathogenicity of S. arenarium was higher with increasing inoculation level representing 82% at the rate of 5 infective juveniles (IJs) while >98% at the rate of >10 IJs. The number of IJs penetrated into the host was 2.7, 5.0, 7.4, and 12.2 at the rate of 5, 10, 20, and 40 IJs, respectively while 24.3 at the rate of 80 IJs and 40.2 at the rate of 160 IJs. Inoculation level did not affect female adult size (4,616 to 6,444
) while affected male adult size (1,600 to 1,934
). The rate of stunted female adults was 70.2% at the inoculation level of 80 IJs and 63.7% at the inoculation level of 160 IJs. The number of progenies was 20,431, 26,696, 47,943, 50,516, 58,701, and 74,235 at the rate of 5, 10, 20, 40, 80, and 160 IJs, respectively. The body lengths of IJs were different depending on inoculation level ranging from 636 to 1,496
