Korean journal of applied entomology, volume 51, issue 3, 2012, Pages 191~205
DOI : 10.5656/KSAE.2012.02.1.084
Because insect visitors was different depending on decomposition stage, dipterans occurred on chicken carcasses depending on postmortem intervals were compared by abandoned sites and decomposition from a serial study on arthropod occurrence from carcasses as forensic indicator. Species occurrence and decomposition of carcasses were different depending on abandoned sites (forest hill, open field, stream, greenhouse and roof), seasons (spring, summer, fall and winter), and situation (burying and non-burying). Development of carcass decomposition was faster at all sites in summer, carcass in greenhouse in winter, and unburied carcasses. Although visiting time of blow flies (Calliphoridae) (Phaenicia sericata, Lucilia illustris, Lucilia sp., Chrysomyia pinguis, and Chrysomyia megacephala) was different depending on abandoned season, their adults were generally collected from carcasses within 2 days. However, there were no visited flies at fresh stage of buried carcasses. The flesh flies (Sarcophagidae) were collected from all sites and seasons, and much faster from unburied carcasses than buried carcasses. Those were collected earlier from carcasses in greenhouse than other sites and occurrence was also shorter. In greenhouse, occurrence time of flesh flies were different depending on season; spring and summer - from fresh to active decay stage, fall - fresh to active decay stage, and winter - advanced decay to remains stage. Calliphora lata, Tricerotopyga calliphoroides, and Aldrichana grahami were dominant species and occurrences were different from other flies. These flies were active mainly from fresh to active stage. Larvae of sarcophagid flies were occurred earlier than those of calliphorid flies on buried carcasses.

The cryptic mealybug, Pseudococcus cryptus, has been increasingly damaging citrus, particularly those plants grown in plastic greenhouses. This study was conducted to monitor the seasonal phenology of adult male cryptic mealybugs and to determine the timing for control using a sex pheromone trap. Adult males responded to a synthetic sex pheromone and trap color. An increasing number of males were attracted to the traps with increasing concentrations of sex pheromone up to 5 mg. The males occurred annually four times and had three cohorts at a time due to different overwintering developmental stages. After overwintering the adult males began to in mid-late April. A positive correlation was observed between the number of adult males caught in traps and the mean density per twig of all motile stages except first stage nymphs of the cryptic mealybugs. The peak time for the first nymph to occur was estimated from the maximum attraction time of the males, and the cumulative degree days (DD) was 350 DD, similar with the preoviposition period.

Korean journal of applied entomology, volume 51, issue 3, 2012, Pages 215~222
DOI : 10.5656/KSAE.2012.04.0.012
Pupation site selection behavior of Plodia interpunctella (H
bner) in response to its larval parasitoid, Bracon hebetor Say, was evaluated. Under the presence of the parasitoid, more moth larvae pupated in a layer deeper than 5 mm. Because the parasitoid searched for the host mostly in the surface layer (< 5 mm), larvae in deeper layers were able to successfully escape attack by the parasitoid. However, this behavior did not affect the numerical response of the parasitoid. The parasitoid laid more eggs per host larvae when the number of attacked larvae decreased.

Some high frequency sounds alter physiological processes of the beet armyworm, Spodoptera exigua. This study investigated the effect of ultrasound (
20 kHz) on larval feeding, pupal development, and adult mating behavior of S. exigua. Ultrasound suppressed feeding behavior of fifth instar larvae, and 30 or 45 kHz treatment inhibited more than 50% of feeding activity. Larvae treated with ultrasound exhibited alterations in major nutrient compositions in the hemolymph plasma. Plasma protein levels decreased with an increase in ultrasound frequency. In contrast, sugar levels increased with an increase in ultrasound frequency. Lipid levels increased with an increase in ultrasound frequency up to 30 kHz and then decreased at treatments > 30 kHz. Hemocytes, the fat body, and epidermis expressed three heat shock proteins and apolipophorin III. Ultrasound treatment markedly inhibited expression of some stress-related genes. Ultrasound treatment also inhibited S. exigua pupal development by extending the pupal developmental period and preventing adult emergence. Last, ultrasound treatment significantly inhibited adult mating behavior, which resulted in a significant decrease in female fecundity. These results show that ultrasound is a physiological stress to S. exigua.

Population dynamics of the American serpentine leafminer, Liriomyza trifolii (Burgess), were observed and modeled in order to compare the effects of air and tomato leaf temperatures inside a greenhouse using DYMEX model builder and simulator (pre-programed module based simulation programs developed by CSIRO, Australia). The DYMEX model simulator consisted of a series of modules with the parameters of temperature dependent development and oviposition models of L. trifolii were incorporated from pre-published data. Leaf surface temperatures of cherry tomato leaves (cv. 'Koko') were monitored according to three tomato plant positions (top, > 1.8 m above the ground level; middle, 0.9 - 1.2 m; bottom, 0.3 - 0.5 m) using an infrared temperature gun. Air temperature was monitored at the same three positions using a self-contained temperature logger. Data sets for the observed air temperature and average leaf surface temperatures were collected (top and bottom surfaces), and incorporated into the DYMEX simulator in order to compare the effects of air and leaf surface temperature on the population dynamics of L. trifolii. The initial population consisted of 50 eggs, which were laid by five female L. trifolii in early June. The number of L. trifolii larvae was counted by visual inspection of the tomato plants in order to verify the performance of DYMEX simulation. The egg, pupa, and adult stage of L. trifolii could not be counted due to its infeasible of visual inspection. A significant positive correlation between the observed and the predicted numbers of larvae was found when the leaf surface temperatures were incorporated into the DYMEX simulation (r = 0.97, p < 0.01), but no significant positive correlation was observed with air temperatures(r = 0.40, p = 0.18). This study demonstrated that the population dynamics of L. trifolii was affected greatly by the leaf temperatures, though to little discernible degree by the air temperatures, and thus the leaf surface temperature should be for a consideration in the management of L. trifolii within cherry tomato greenhouses.

Benzylinedeneacetone (BZA) is a bacterial metabolite which is synthesized by at least two entomopathogenic bacteria, namely Xenorhabdus nematophila and Photorhabdus temperata subsp. temperata. It has been shown to possess inhibitory effects on insect cellular and humoral immune responses as well as antimicrobial activities against various species of bacteria and fungi. However, its relatively high phytotoxicity, and nonsystematic effect have thus far prevented its development into an optimal pesticide. This study screened five different BZA derivatives in order to select an optimal compound, which would have relatively high solubility and low phytotoxicity while retaining sufficient degrees of the immunosuppressive and antimicrobial activities associated with BZA. Hydroxylation of the benzene ring of BZA was found to significantly suppress its immunosuppressive and antimicrobial activities. Transformation of the ketone of BZA by carboxylation also suppressed the inhibitory activities. However, a shortening of the aliphatic chain of BZA into acetate form (4-hydroxyphenylacetic acid: HPA) did not decrease the inhibitory activity. HPA also showed much less phytotoxicity against the hot pepper plant Capsicum annuum, when compared to BZA. This study identified an optimal BZA derivative, which exhibited relatively little phytotoxicity, but retained a high degree of inhibitory activity to suppress insect immune responses and antimicrobial activities against plant pathogens.

High frequency sounds disrupt physiological processes, such as feeding behavior, development and immune responses of Spodoptera exigua. We analyzed high frequency sounds with respect to biochemical changes in S. exigua. High frequency sound (5,000 Hz, 95 dB) suppressed protein synthesis and secretion of midgut epithelium. It also significantly inhibited a digestive enzyme activity of phospholipase
. The gene expression of three different heat shock proteins and apolipophorin III was altered, particularly in midgut tissue in response to high frequency sound treatments. High frequency sound treatments significantly increased sugar and lipid levels in hemolymph plasma. These results suggest that high frequency sounds are a physiological stress that induces biochemical changes in S. exigua.

Korean journal of applied entomology, volume 51, issue 3, 2012, Pages 285~293
DOI : 10.5656/KSAE.2012.05.0.033
Occurrence Hyphantria cunea was confirmed in 35 cities and counties nationwide in 2011, each of which reported some form of crop and/or ecological damage caused by the moth. Only a larva of the black-headed form were reported to have occurred in the nation. H. cunea was found in street trees 66.7%, followed by landscape trees 19.4% and forests 13.9%. This suggests that artificial environment 86.1% suffered from H. cunea more severely than natural forests. The study identified 44 families and 102 species of host plants, and found an additional 29 species, to those which had been identified in previous studies. At present, the identified host plants of H. cunea are composed of 62 families and 219 species in total since their first appearance was reported approximately 50 years ago. Host plants include 5 species of food crops (2.3%), 6 species of vegetables (2.7%), 4 species of medicinal crops (1.8%), 1 species of industrial crops (0.5%), 13 species of fruit trees (5.9%), 6 species of other trees crops (2.7%) as well as a further 5 species of farmed crops (2.3%). Seven species of host plants (18.4%) originate from North America where Hyphantria cunea has been introduced from, while 11 species (29.0%) are from China and Japan, Europe and India were the native sources of (10.5%) of the origin with 4 species, respectively. Seventeen species of trees, including Platanus occidentalis L., Ulmus davidiana (var.) japonica (Rehder) (Nakai) and Cornus officinalis (Siebold & Zucc) were heavily noted to be heavily infected with larval populations.
