A New Species of the Genus Incabates Hammer (Acari: Oribatida) from Jeju, Korea
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 171~175
An oribatid mite, Incabates barbatus sp. nov. in the family Haplozetidae is described herein from Korea. This new species is very similar to 1. major reported in Japan. However, prodorsal setae (ro & la) and head of sensillus are smooth in 1. major while barbs are found on the outer margin in the middle of rostral seta (ro) and lamellar seta (la) in addition to the presence of spinulae making the surface of head of sensillus rough in the new species. There are altogether 9 species described in the genus Incubates at present including the new species reported herein and keys to these 9 species are presented.
Seasonal Occurrence and Damaged Aspects of Frankliniella occidentalis Pergande (Thysanoptera: Thripidae) by Cultural Environments and Varieties of Chrysanthemum
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 177~181
This study investigated seasonal occurrence of Frankliniella occidentalis and its damage on chrysanthemum from 1999 to 2000. F. occidentalis adults were attracted to yellow sticky traps from early April to harvesting time in the field. The highest densities were observed from late April to mid-June in spring culture and from mid-August (just after transplanting) to early September in autumn culture respectively. Seasonal fluctuation in a PVC green house was similar to that in the field. Number of insects per flower were higher in the green house than that in the field. Leaf damages due to the insects were observed from mid-May and increased as chrysanthemum grows (R
**/, p> 0.01).
Scarabs (Coleoptera: Scarabaeidae) in Sweet Persimmon Orchard and Effect on Sweet Persimmon
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 183~189
Occurrence of scarabs at sweet persimmon (Diospyros kaki var. Fuyu) orchards was investigated by mercury light traps every one week interval in several areas in Gyeongnam province including, Jinju, Sacheon, Sancheong, and Gimhae, from April to September in 2000 and 2001. In addition, damage of persimmon by scarabs was observed every ten days interval at three orchards in Jinju and at one in Gimhae from late May to late October. Although sixteen species of 12 genera were attracted to the traps, species and number of catches were different according to orchards and years. Holotrichia morosa was most dominant in Jinju, Sacheon, and Sancheong. Total number of scarabs attracted to the traps was highest at the orchard surrounded by chestnut orchards in Sancheong. Fruits of sweet persimmon were not damaged by scarabs at the studied orchards. However, leaves and calyxes were slightly damaged by Adoretus tenuimaculatus. Maximum average numbers of the damaged leaves and calyxes throughout the year by A. tenuimaculatus were 0.33 leaves from 10 new shoots and 0.07 calyxes from 15 fruits. Gametis jucunda and Popillia mutans damaged flowers and calyxes. Maximum average numbers of damaged flowers and calyxes by these 2 species were the same as 0.03 from 15 flowers and 15 calyxes, respectively. These levels of damage suggest that the scarabs are not economically injurious to sweet persimmon fruits in Korea.
Occurring Season of Overwintered Bumblebee Queens in Korea and Their Visiting Flowers
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 191~197
Seasonal occurrence and visiting flowers species of overwintered bumblebee queens were investigated during the spring season of 2000. A total of 1,277 overwintered bumblebee queens were collected, consisting of seven species of Bombus and one species of Psithyrus. The dominant species were Bombus ardens Smith and Bombus ignitus Smith. The heydays of their occuring season were the early April for B. ardens and the second half of the May for B. ignitus. B. ignitus was mainly collected on Prunus yedoensis Matsumura and Corydalis speciosa Min, and B. ardens on the Rhodldendron mucronulatum Turcz and Prunus yedoensis.
Effects of Temperature on Development of Oligota kashmirica benefica(Coleoptera: Sthphylinidae) and Its Seasonal Fluctuation in Yuzu Orchards
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 199~204
Population fluctuation of O. kashmirica benefica, a major natural enemy of citrus red mite (Panonychus citri), was surveyed from 1997 to 2000 in yuzu orchards in Goheung region and, developmental periods, developmental threshold temperature (DT) and effective cumulative temperature (ET) were estimated. Under four constant temperatures of 15, 20, 25 and 30
, developmental periods from egg to adult of the beetles were 67.3, 31.4, 19.4 and 15.3 days, respectively. The period of each stage was long in the order of pupa> egg > 3rd larva> 2nd larva> 1st larva. Mean numbers of eggs oviposited by a female per day were 3.3, 5.6, 7.3 and 7.7 under the temperatures, respectively. The highest hatchability (92%) and adult emergence (60%) were shown under 25
. Adult longevity was 54.3 days for females, and 58.6 days for males. In natural condition, the sex ratio of the beetle was 0.58. Developmental thresholds (DT) for egg, 1st, 2nd, 3rd larva, pupa, and egg to adult were 12.7, 10.0, 10.8, 7.9, 10.1 and 10.6
, respectively. The effective cumulative temperatures (ET) were 41.4, 22.9, 22.7, 46.6, 165.3, 292.9 day-degree at the same development stage, respectively. The beetle occurred from early April to early December in yuzu orchards. The population peak of the beetles was dependent on the amount of prey mite (Panonychus citri), and the ratio of the predator to prey mite was 1 to 100-200 at predator peak stage in the field.
Effects of Temperature on Reproduction and Development of Udea ferrugalis(Lepidoptera: Pyralidae)
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 205~209
Effects of temperature on the development and reproduction of the Udea ferrugalis Hubner were investigated at various temperatures (10, 15, 18, 20, 23, 25, 27, 30
). The development times of eggs, larvae, prepupae and pupae were shorter in higher temperatures than in lower ones. Egg and pupa did not develop at 10
. The lower developmental threshold temperatures for eggs, larvae, pupae were 9.5, 9.6 and 11.9
, respectively, and their thermal requirements for development completion were 87.9, 200.9 and 119.7 degree-days at the same temperature, respectively. Adult longevity was 25.2 days at 15
, 7.3 at 23
and 5.3 at 30
. Mean fecundity per female was higher at 20-23
compared to other temperatures. Mean generation time in days (T) was shorter in higher temperature region. Net reproductive rate per generation (Ro) was lowest at 15
(138.2) and it was highest at 20
(265.4). The intrinsic rate of natural increase (r
m/) was highest at 25
as 0.247. As a result, it was considered that optimum range of temperature for U. ferrugalis growth was 20.0 to 23
Effect of Host Plants on the Development and Reproduction of Cotton Caterpillar, Palpita indica (Saunder)
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 211~216
The present study was aimed to examine the effect of different host plants on the biological property of cotton caterpillar, outbreak pest of cucurbit vegetables. The feeding and oviposition preferences toward cucumber and pumpkin were greater than those toward watermelon, oriental melon, and melon. The periods of egg and larva fed on oriental melon, melon, and pumpkin were longer than those on watermelon and cucumber. The longest pupal period was 10.5 days from cucumber. The hatching rate, pupation rate, emergence rate, and survival rate were observed from different host plants. The hatching rate was the highest on cucumber (87.2%) and the lowest on melon (72.8%). The pupation rate on watermelon and oriental melon (90.0% and 89.1%, respectively) was higher than that on cucumber (62.0%). The emergence rate on cucumber and pumpkin (93.5% and 92.0%, respectively) was higher than that on oriental melon (78.7%). The survival rate from hatching to emergence on watermelon (76.0%) was the highest, and the lowest on cucumber (50.0%). The adult period on melon (21.0 days) was the longest, and the shortest on cucumber (15.5 days) among 5 host plants. Average number of eggs per female on cucumber (281.8 eggs) was the highest, and the least on oriental melon (96.6 eggs). The survivorship on cucumber was the longest (30 days), and the shortest on pumpkin (17 days). The preoviposition period on oriental melon and melon (3.4 days) was longer than that on watermelon (2.1 days) and mean generation time in day (T) on melon was the longest (47.2 days) though they were not significant. The net reproductive rate per generation (R
) on cucumber, 191.3, was the highest and the highest intrinsic rate of natural increase (r
) was observed from cucumber as 0.127. All these results suggest that the growth ana reproduction of cotton caterpillar varies depending upon the kind of host plants. The analysis of the life table revealed that cucumber and pumpkin were the favorable host plants of cotton caterpillar.
Damage of Perennial Ryegrass, Lolium perenne by Chestnut Brown Chafer, Adoretus tenuimaculatus (Coleoptera: Scarabaeidae) and Biological Control with Korean Isolate of Entomopathogenic Nematodes
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 217~223
The chestnut brown chafer, Adoretus tenuimaculatus Waterhouse, is serious insect pests in golf courses. Adults feed on the leaves of latifoliate trees but larvae feed on roots of turfgrases such as bentgrass, Agrostis spp. Damage of A. tenuimaculatus larvae was observed at the Jinju golf club which showed damage symptom on perennial ryegrass, Lolium perenne in tees and fairways in July, 2000. Damaged turf by A. tenuimaculatus larvae became yellowish and wilted. Symptom of laval damage of A. tenuimaculatus was similar to summer depression in warm season turfgrasses but not recovered by irrigation when Korean isolates of entomopathogenic nematodes were evaluated for the control of A. tenuimaculatus larvae in laboratory and field as a possible biological control agent. The nematodes used were Heterorhabditis bacteriophora Jeju strain, Hererorhabditis sp. Gyeongsan strain, Steinernema carpocapsae Pocheon strain, S.glaseri Dongrea strain, and S.longicaudum Nonsan strain. In the laboratory test H.bacreriophora Jeju strain and Heterorhabditis sp. Gyeongsan strain were highly effective for 3rd instars with 95% mortality. In the field test reduction rates of A.tenuimaculatus larvae were higher by ranging from 28 to 57% by H. bacteriophora Jeju strain, Heterorhabditis sp. Gyeongsan strain, and S.carpocapsae Pocheon strain compared to 7% by natural cause.
Effect of Entomopathogenic Nematodes on Egg Mass Formation by the Northern Root-knot Nematode, Meloidogyne hapia
Korean journal of applied entomology, volume 41, issue 3, 2002, Pages 225~231
The entomopathogenic nematodes, Steinernema carpocapsae All strain (ScA), S.glaseri NC strain (SgN) and H. bacteriophora NC 1 strain (HbN), were evaluated for the effects on egg mass formation by the northern root-knot nematode, Meloidogyne hapla in pot experiment using tomato. In the first experiment, 2.5
infective juveniles (Ijs) of entomopathogenic nematodes were inoculated to 100 g of the soil infected with ca. 450 Ijs of M. hapla/100 ㎤ in 150
container. The number of egg mass was significantly decreased to 9.4-36.5 in ScA, to 5.7-24.7 in SgN and to 11.2-16.0 in HbN treatments compared with 62.5 in M.hapla alone. In the second experiment, ScA and S.carpocapsae Pocheon strain (ScP) and SgN and S.glaseri Dongrae strain (SgD) were treated to 350 g of the soil infected with 100, 200 M.hapla larvae/100 ㎤ in 450
container The entomopathogenic nematodes were inoculated at the rate of 2,020 Ijs and 1.6
105 Ijs in 350 g soil. The number of egg mass of M.hapla were significantly decreased in the entomopathogenic nematode treatments compared with M.hapla alone although no differences were observed among Steinernema species, strains, or infection concentrations. Treatments of entomopathogenic nematodes 3 days before M.hapla inoculation were more effective on reduction of egg mass formation than those of 3 days after M.hapla treatments. Growth of tomato was not affected by entomopathogenic nematode treatments.
