Host Plants of Popillia quadriguttata (Coleoptera: Scarabaeidae)
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 15~19
Host plants of Popillia quadriguttata (Fabricius) were investigated in golf courses, Fifteen plant species of 15 genera in 13 families were confirmed as host plants of P. quadriguttata. Thus, total number of host plants of P. quadriguttata was 26 species of 25 genera in 18 families including 11 recorded species in literature. In addition, P. quadriguttata adults fed on 30 plant species of 25 genera in 19 families out of the 69 plant species of 53 genera in 33 families supplied as food in laboratory, P. quadriguttata adults preferred Wistaria floribunda in golf courses but Tilia mandshuric, Platanus orientalis, Diospyros lotus, Punica granatum and Chionanthus retusa in laboratory.
Ovipositional Charcteristics of Hemiptarsenus zilahisebessi(Hymenoptera : Eulophidae), Ectoparasitoid of Liriomyza trifolii (Diptera: Agromyzidae)
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 21~25
Longevities of Hemiptarsenus zilahisebessi, ectoparasitoid of Liriomyza trifolii (Burgess) larva. were 23.0, 16.9. and 12.7 days at 20, 25, and 30
, respectively. The adults copulated and laid eggs as soon as they emerged at 20
. The total number of eggs laid and the daily oviposition rate were 82.3/3.6, 90.3/6.0, and 95.5/7.8 at the three different constant temperatures. The sex ratios were 0.37,0.43. and 0.43 at 20,25, and 30
. respectively. Female oviposited 1.4 eggs near parasitized host larva and the average distance between eggs of H. zilahisebessi andhost larva wre 0.92mm. The instrinsic increase rates(r
m/) of H. zilahisebessi were 0.12, 0.19 and 0.27, and net reproduction were 31.0, 40.2, and 40.8 at 20,25, and 30
, respectively. Female of H. zilahisebessi oviposited mainly on the 3rd larva and sex ratio was 0.42, wheras the ratio was declined to 0.1 on the 1st larva.
Analysis of Spatial Coincidence of Thrips and Orius sauteri on Greenhouse Eggplants
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 27~32
Biological control of thrips with a predatory bug species, Orius sauteri Poppius, was evaluated in an eggplant greenhouse, To study the biological control strategy of thrips. three Plots were established: Orius sauteri released plot without pesticide treatment (NRT), pesticide treated plot (PAT), and natural enemy removed plot (RNT) The nymphs of O. sauteri were found on the upper side of leaves in NRT at 21 days after the first release of O. sauteri. The density of thrips were dropped and maintained at lower level in NRT than in RNT. Average damage index of NRT, PAT and RNT was 1.35, 1.21 and 2.90 and the percentage of damaged fruit ratio of those was 70.3, 68.6 and 99.0%, respectively. The damage index and percentage of damaged fruit in NRT were slightly higher than those of PAT, but much lower than in RNT. Taylor's band Iwao's
were greater than 1 for both populations. indicating aggregated distribution. Spatial coincidence index of O. sauteri was high most of the time even at low densities of both populations. The refuge index for thrips decreased as O. sauteri density increased. Results of this study suggest that O. sauteri is a promising natural enemy for thrips control on eggplant.
Mirid Bugs (Heteroptera: Miridae) on Grapevine: Their Damages and Host Plants
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 33~41
The mirid bug damages on grapevine were observed not only on young shoot and leaves (decoloration, deforming, and perforation) but also on fruits (black spot, corky scar, and young fruit shattering). Among 159 fields surveyed throughout the country, 113 fields (71%) were damaged, and the damages were relatively severer in the chief producing districts of grape vine, such as Gimpo, Anseong, Naju, Gimcheon, Buyeo, Daejeon, Yesan than other districts where grapevine yards were not concentrated. The severest shoot damages were observed in two grape vine yards of Naju (85%) and Gimpo (65%) in 1999. Three species of virid bugs were recognized on grape vine tree, Apoygus spinolae (Meyer-Dur), Apolygus lucorum (Meyer-Dur), and Orthotylus (Melanotrichus) flavosparsus(Sahlberg). Among them, A. spinolae was dominant species in the number of specimens collected. A. spinolae were collected on 10 host plants including Vitis vinifera L., Prunus armeniaca var. ansu Max., and prunus serrulata var. spontanea(Max.) Wils. and etc., and A. lucorum were collected on 10 species of plants, including Artemisia iwayomogi Kitamura, Artemisia princeps var. orientalis(Pampan) Hara and etc. Both A. spinolae and A. lucorum distributed widely in Korean grapevine yards
Ecological Characteristics of Protaetia orientalis submarmorea (Burmeister) (Coleoptera: Cetoniidae)
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 43~47
This study was carried out to investigate the ecological characteristics of Protaetia orientalis submarmorea (Burmeister). The emergence period of adults is appeared from April to October, and most abundant in July∼August, once a year in the field. Hibernation took place mostly in larval stage, but some in adult stage, and were generally found in the decayed rice straws and in the soil covered with compost or similar materials with average depth of 17.6 cm The developmental characteristics in the insectary (28
, 70% RH, 16L: 8D) was investigated: the average number of eggs laid per female is 82.8, egg period 8.4 days, 1st instars of larva 10.6, 2nd 18.7, 3rd 38.1, and pupal period 35.5 days. Longevity of the adult was 135.2 days In the female and 121. 7days in the male.
Polyclonal Antibody against Paenibacillus larvae and its Application
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 49~53
Paenibacillus larvae is a gram-positive, spore-forming bacterium that is etiological agent for american foulbrood disease (AFB), which is the most severe disease in honey bee. To detect P. larvae from infected honeybee-comb or larvae, polyclonal antibody against whole bacterium was produced from guineapig and its specificity was evaluated. After optimization of ELISA-based detection system using these antibodies, a number of different P. larvae strains were analysed. Polyclonal antibody against P. larvae ATCC 25747 showed high affinity to most strains of P. larvae including P. larvae. strain ATCC 9545 (type strain), ATCC 25747 and other korean strain, SJl5 but exhibited no cross-reaction with other bacterial species. Additionally, this type of ELISA system was used for the detection of AFB in field-application The results have shown that this antibody could be useful for the rapid identification and monitoring of P. larvae in honeybee-comb.
Comparison of Predation Rates of Three Phytoseiid Mite Species on Citrus Red Mite (Panonychus citri McGregor) on Citrus Tree
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 55~60
Predation amount and density suppression ability of three species of phytoseiid mites (one native, Amblyseius womersleys Schica; two introduced species, Amblyseius fallacis Garman and Typhlodromus occidentalis Nesbit) on Panonychus citri McGregor were examined in laboratory condition (25
, RH 65
5%, 16L:8D). A. fallacis and T. occidentalis consumed 20.1 and 9.1 eggs of P. citri, respectively, whereas A. womersleyi consumed 1.1 eggs. When each larva, protonymph and deutonymph of P. citri were supplied as prey for 24 hours. A. womersleyi consumed 23.8, 16.5 and 9.0, and A. fallacis consumed 26.1, 18.2 and 7.4, respectively. However, T. occidentalis consumed only 7.8, 4.2 and 4.2. respectively Density suppression ability of A. womersleyi and A. fallacis against P. citri was very high at the release ratios of 20 : 1 (prey : predator). However, T. occidentalis did not regulate P. citri population effectively Developmental periods from egg to adult of A. womersleyi and A. fallacis was 6.1 and 5.9 days at 25
Parasitism of Liriomyza trifolii (Diptera: Agromyzidae) by Hemiptarsenus zilahisebessi(Hymenoptera: Eulophidae) on Tomato
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 61~65
This study was conducted to investigate percentage of parasitism and control effect of Liriomyza trifolii by Hemiptarsenus zilahisebessi on tomato. Percentages of parasitism on L. trifolii larva by ectopatasitoids war e 26∼45% Among them the parasitism by H. zilahisebessi was highest as 47∼75% in tomato. The parasitoids preferred 1 st to 3rd instar of host larvae. In laboratory test, the parasitoids showed high parasitism on 3rd instar larvae of host by 89.8∼93.1% when the female parasitoids were introduced by the ratios of 1 : 10, 1 : 20, and 1 : 30. In field test, 3 or 5 female parasitoids were introduced per plant. In the case, the parasitism increased to 80% 4 weeks after introduction of the parasitoids. This increased parasitism was resulted from density reduction of the host larvae There were no significant differences in parasitism, density of alive host, and percentage of damaged leaf between inoculation density.
Management Strategies for Apolygus spinolae(Hemiptera: Miridae) in Grapevine Yards
Korean journal of applied entomology, volume 41, issue 1, 2002, Pages 67~73
Studies were conducted to investigate the control effects of several insecticides on Apolygus(=Lygocoris) spinolae(Meyer-Dur) and to develop its management strategies in grapevine yards. Of insecticides which were applied by farmers in commercial grapevine yards, chlorpyrifos, parathion, fenvalerate, and esfenvalerate
fenitrothion showed good control effects against A. spinolae. In designed field experiments of fenitrothion and chlorpyrifos for the evaluation of A. spinolae control, both insecticides showed high control efficacy of 94.8 and 91.6%, respectively. The damage of A. spinolae was examined in a grapevine yard, where five different combinations of application timing and number were treated with fenitrothion to assess yield losses (average cluster weight) by A. spinolae. There were no significant differences among average cluster weights of sprayed vines; 466.0 g in sprayed vines on 2 to 3 leaves unfolded stage, 460.7g in sprayed vines on flower separating stage, 465.0 g in sprayed vines each on 2 to 3 leaves unfolded and flowers separating stage, and 487.4 g in sprayed vines each on 2 to 3 leaves unfolded, flowers separating and fruit set stage. Weights of fruit clusters of unsprayed vines was significantly lower than those of sprayed vines. Based on yield and spray cost, chemical control on 2 to 3 leaves unfolded stage produced higher net income than each spray on 2 to 3 leaves unfolded and flower separating stage (i.e., two times of spray), and produced similar net income as each spray on 2 to 3 leaves unfolded, flowers separating and fruit set stage (i.e., three times of spray). Thus, the 2 to 3 leaves unfolded stage was economical spray timing to controlA. spinolae in grapevine yards. Also, management strategies for A. spinolae were discussed.
