The occurrence of tobacco whiteflies, Bemisia tabaci, in greenhouses was monitored in Korea in 2005. Bemisia tabaci occurred in the rose, sweet pepper, tomato, and cucumber greenhouses of Chungbuk, Chungnam, Gyongnam, and Jeonnam Provinces, but not in Jeonbuk and Gyongbuk Provinces. The biotypes and genetic differentiation of the whiteflies collected in each regions were analyzed by mitochondrial 16S DNA sequences. The 16S DNA sequences of Jincheon (Chungbuk Province) samples were similar to DNA data reported from Japan and Israel which were known as the B biotype. However, the DNA sequences of the Buyeo (Chungnam), Geoje (Gyongnam) and Boseong (Jeonnam) collections, which were 100% homologous showed over 99% similarity to the DNA of Q biotype from Spain and Egyrt. Here we report the first founding of the Q biotype in Korea. It is assumed that, unlike the B biotype reported from Jincheon since 1998, the Q biotype might have been introduced recently from the certain foreign region/country to the greenhouses in those provinces.

For the comparison of feeding behavior of Nilaparvata lugens among different rice varieties, electrical penetration graph (EPG) technique was used. Ten rice varieties were selected from national-widely recommended rice varieties cultivating in Chungnam province. The correlation between feeding duration and honeydew amount excreted was investigated, and the types of EPG pattern were analyzed among rice varieties. The EPG patterns divided into 6 types according to electrical specific feature, respectively. Type 1 pattern was a searching feeding sites, resting or wandering on a rice plant. Type 2 pattern was appeared when the insect untaken from phloem sieve element. Type 3 pattern was observed when the insect piercing into the rice plant. Type 4 pattern was observed when the insect salivating in rice plant. Type 5 pattern was observed when the insect ingesting from the xylem. Type 6 pattern was observed when the stylet moving in cell. Feeding duration time on Gum-nam was significantly shorter than Dong-jin, Dae-ahn, Dong-ahn, Dae-san. Also, on Gun-nam, it was shown that the brown planthopper did not penetrate the cuticle for a long time. The total number of excreted honeydew droplets by the brown planthopper was the greatest in Dong-jin variety and the least in Gum-nam variety. In proportion to phloem feeding time, the number of honeydew droplets had been increased. According to the results of EPG patterns and honeydew droplets analysis, N. lugens seems to prefer Dong-jin, Dong-ahn, Dae-san, and Dae-ahn to Gum-nam, Da-san, and Nam-chun rice plant variety.

Cellulose-digesting bacteria were isolated from hindgut of Allomyrina dichotoma (Coleoptera: Dynastidae). The bacterial isolates were identified as Yersinia sp. and Bacillus sp. The addition of the identified bacteria to diet increased growth rate of the cetoniid beetle, Protaetia brevitarsis senlensis (Coleoptera: Cetoniidae), probably by digesting cellulose nutrient contained in the oak tree sawdust diet. An additive of wheat flour at more than 10% to the sawdust diet significantly enhanced growth of P. brevitarsis senlensis. Trimmed branches of apple trees have been disposed in the apple farms and could be used for a diet component of the cetoniid beetle when the cellulose-digesting bacteria were mixed with the derived-sawdust. Resulting manure from mass rearing of P. brevitarsis senlensis contained high organic matters and trace amounts of toxic metals. When the manure were splayed on soil, it was effective as a natural compost and significantly stimulated lettuce growth. This research suggests a model technology to use cellulose-digesting bacteria to use for culturing grub, which results in natural recycles of trimmed branches in apple farms as grub diet, and to use grub manure as a natural compost.

Korean journal of applied entomology, volume 44, issue 3, 2005, Pages 199~205
Seasonal occurrence and ovarian development of the bean bug, Riptortus clavatus Thunberg (Heteroptera: Alydidae), were studied at a soybean field and an university campus in which host plants are less available for the bug in Gyeongnam province with aggregation pheromone traps in 2004. It was assumed that the bug passed three generations per year at the university campus. Adults of the 1st generation might occur from early July to early August and that of the 2nd one from mid August to late September. Adults of the 3rd generation occurred from early October to mid November, entered reproductive diapause without carrying eggs in the ovaries of females during winter, and resumed activity from late March of the next year. Full-grown eggs in the ovaries of the overwintered females were first observed at the 1st half of May. Two peaks of occurrence, from early August to mid September and from mid October to mid November, were shown at soybean field that was sowed on May 24. The two peaks almost corresponded to those of the 2nd and 3rd generations at the university campus, respectively.

Korean journal of applied entomology, volume 44, issue 3, 2005, Pages 207~212
This study was performed to investigate the bionomical characteristics of Allomyrina dichotoma in Korea. The imaginal stage was from late June to late August, and the advent of imagoes was the most frequent in mid-July. The larvae inhibited in humus and the period of larva was all completed in late October. At the stage of the third larva, the larvae entered into the hibernation. The average number of laid eggs was 24, and all periods of each stage - eggs, first, second, third instar larvae and pupa - were shortened in
. As for the longevity of imagoes, female, reared in individual and in low temperature lived longer than male, in group and in high temperature, respectively.

Adult development and fecundity of the green peach aphid, Myzus persicae
, were studied at
RH under 16L:8D and the results were put together to build a life table. The longevity shortened as temperatures rose at and below
whereas it remained relatively constant at
. Total fecundity was not significantly different at all temperatures except at
. Daily fecundity gradually increased from
. It was 5.1 at
and as temperatures either went down or up, it decreased to 2.8 at both
. Fecundity model built from total fecundity at various temperatures suggests that
was the optimum temperature for the maximum progeny of 51. Net reproduction rate RO was highest of 36.5 at
. The intrinsic rate of increase per day
and the finite rate of increase per day
were highest of 0.4 and 1.6, respectively and the doubling time Dt was shortest of 1.6. Constructed life table suggests that the optimum temperature for adult development for the green peach aphid was
at which the mean generation time was 8.1.

This study was conducted to investigate the developmental characteristics of cabbage armyworm, Mamestra brassicae L. (Lepidoptera: Noctuidae) by different temperatures and its seasonal occurrence in pepper field. Under four constant temperatures, 15, 20, 22 and
, developmental periods from egg to adult were 88.3, 63.0, 52.3, and 42.8 days, respectively, with egg periods being 9.2, 6.2, 5.0 and 3.9 days, and larval periods being 40.5, 30.1, 23.3 and 21.2 days, respectively. Developmental threshold and thermal requirement in degree-days (DD) were
and 69.4 DD for egg,
and 434.8 DD for larva and
and 344.8 DD for pupa. Fecundity of female increased as temperature increased laying 1262.1 eggs at
, 1663.8 eggs at
and 1763.2 eggs at
. Mean numbers of eggs per egg-mass were 99.4, 114.7 and 167.9 under the three constant temperatures, respectively. In Daegwallyeong highland area, this noctuid occurred from mid June to late August and has two generations a year reaching peak two times, one at late June and the other at early August.
Oviposition Time of Overwintered Females and Migration of Crawlers of Pseudaulacaspis prunicola (Homoptera: Diaspididae) on Cherry Trees in Jeju Island
Kim, Dong-Soon ;
Korean journal of applied entomology, volume 44, issue 3, 2005, Pages 231~235
This study was conducted to obtain the optimal spray time for Pseudaulacaspis prunicota (Maskell) (Homoptera: Diaspididae) in early seaon in Jeju. Oviposition time of overwintered females and activity of hatched nymphs of P. prunicola were monitored, and the phenology data were compared with the outputs estimated by a degree-days model of P. pentagona (Targioni-Tozzetti)). Overwintered females of P. prunicola began to lay eggs from mid to late April, and the eggs started to hatch from early May followed by the active migration of the hatched nymphs during mid May. The phenological events of P. prunicola in early season were likely comparable with those of P. pentagona reported in southern Korea and in central Japan. A degree-day model, which predicts the proportion of >50% hatched egg batches of P. pentagona (y=1[exp(-(-a+bx))]; y, proportion; x, degree-days based on
from 1 January; a=-18.80 and b=0.073), accurately described the migration time of P. prunicola hatched nymphs. Thus, it is considered that the degree-day model can be used for predicting the optimal spray time for P. prunicola in early season.

Biological control of Indian meat moth (Plodia interpunctella (
)) by iterative mass release of its larval parasitoid, Bracon hebetor Say, was tested in a large wheat elevator (diameter 8 m, height 41 m) containing 6,000 t of wheat. Adult parasitoids were released seven times from July 23 to September 3, 2002. The number of parasitoid adults per release time varied from 3,000 to 10,000 so that the total number released was 50,000. The moth population density in the parasitoid-released elevator was maintained at a level of
compared to the moth population in untreated elevators.

Korean journal of applied entomology, volume 44, issue 3, 2005, Pages 243~249
We investigated the repellency of eight mosquito repellents against Culex pipiens pallens and Aedes albopictus, and the quantity of DEETs were analysed by using gas chromatography. Ae. albopictus showed higher bloodsucking efficacy than Cx. pipiens pallens of the two subjects mouse and human hands, and human hand was more efficacious method for mosquito bloodsucking efficacy than mouse. Among the eight repellents were tested with mouse as subjects for eight hours, product C, G, and H were high repellency than others. In the case of human hands as subject, product C was highly effective than above other products. The DEET quantities of eight repellants varied from 7.31 g to 38.9 g in 100 g contents and we ascertained that there was a correlation between mosquito repellency and the DEET quantities remained after the treatments. It was evidenced from the long term test with shirt piece, in this test the Ae. albopictus attack was increased when the DEET quantity decreased below 40%.

The occurrence and the host plants of Arboridia kakogawana and A. maculifrons in the province of Chungcheonbuk-Do were observed. They started to infest grapevine in a vineyard in early May and reached peak population two times once in late June and once in mid August in general. In preparation for overwinter, A. kakogawana moved to the nearby forest in search of a tree with bark from early October. A. maculifrons also moved to the weeds on the ridge of vineyard circumferences from the end of September. Population density of the two species were found to be the highest in Okcheon county among the five counties of Chungbuk province. Developmental period of A. kakogawana was shorter than that of A. maculifrons.
