Presticide Resistance Menagement of Pest and Beneficial Arthropods and More Biologically-Based IPM on Apple
Croft, B.A. ;
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 373~381
Resistance evolution to organophosphate-based pesticides in apple and pear inhabiting arthropods of western North America extends to many classes of pest and some beneficial species. Resistance management programs to minimize resistance in pests while exploiting it in natural enemies have met with mixed success. Among beneficials, resistances have been exploited mostly among predators of pest mites. Evolution of resistant mites, leafminers, leafhopper, aphids, leafrollers and some internal fruit feeders have led to development of new monitoring methods and means to delay or avoid resistance. But it is resistance to azinphosmethyl in codling moth (Cydia pomonella) that is changing the pest control system and moving it from chemical to biologically-based means. Newly merging IPM system will depend more on use of biological, cultural, behavior and genetic controls. But more selective pesticides also will be needed to augment pheromones, resistant host plants and genetically altered organisms. These more biologically-based tactics will be prone to resistance evolution in pests as well, if used too unilaterally and/or too extensively.
Evaluation for Biocontrol Potentials of Nematophagous Fungi against Root-knot Nematode
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 382~388
Five nematophagous fungi, Arthrobotrys arthrobotryoides, A. conoides, A. oligospora, Dactylella lobata and Fusarium oxysporum were evaluated for nematicidal effect on Meloidogyne hapla in greenhouse. Treatment of nematophagous fungi reduced the root galling by M. hapla and increased red-pepper growth in naturally infested pot soil. Number of galling were significantly less inall pots in 4 different inoculum densities of 5 nematophagous fungi compared to untreated plots. Especially, treatment of F. oxysprum resutled significant reduction of root gall of red-pepper. The increased shoot growth was significantly higher in pretreated plots by A. arthrobotryoides, A. conoides, A. oligospora, D. lobata and F. oxysporum at inoculum concentration of 1:100 but other treatments were not significantly increased shoot growth. Two promising fungi, D. lobata and F. oxysporum were selected in greenhouse test and in vitro results of previously experiment and applied to field plot naturally infested by M. hapla serverely. Number of galls were remarkably fewer in plots treated with D. lobata and F. oxysporum at either 1:70 or 1:100 concentration compared to the untreated plots. The shoot growth of red-pepper was increased strikingly in the plots following the red-pepper was increased strikingly in the plots following the treatment of both fungus than greenhouse test.
Seasonal Fluctuation of Beet Armyworm, Spodoptera exigua (Hubner), Adult and Larva
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 389~394
Seasonal fluctuation of Beet armyworm, Spodoptem exigua, adults and larvae were momtored by pheromone trap and direct obseration in the welsh onion field, respecLively. Adult peaked on mid~late November and occurred 4 Limes a year by pheromone trap at Yesan, 1990. There were 3 peaks a year at Asan, 1991. The highest number of adults were caught on early September. In Suwon, the yearly number of adults caught by pheromone trap was high in the order of 1990, 1991, and 1992. In 1992, the moLh was initily caught on mid April by pheromone trap at Koheung, Chonnam, and it vms 3 month earlier than that at Suwon. The larvae of beet armyworm at welsh onion field at Asan, 1991 was first found on late June and gradually increased until mid September. The density at peak occurrence was about 20 individual per 100 hills of welsh onion. The peak of the larvae appeared 20 days after peak emergence of adult. It is expected that there are 4 times of occurrence when the first egg of beet armyworm IS laid on mid May at Suwon. It takes 48, 25, 23, and 58 days to complete 1st, 2nd, 3rd. and 4th generation, respectively.
An Artificial Diet and the Rearing Method for the Asian Corn Borer, Ostrinia furnacalis (Guenee) (Lepidoptera; Pyralidae)
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 395~406
This experiment was carried out to develop an artificial diet and a mass rearing system, which is essentIal in the pheromone research for Ostrmia furnacalis. Component deletion and addit.ion methods were applied t.o define the nut.ritional Importance of some components, especially yeast, Wesson's salt mixture and vitamin complex. Secondly we have developed a proper rearmg syst.em for O. furnacalis. and also tried to find out the factors affecting rapid sclerotization (dark-canning) of pupae. AddItion of yeast raIsed the pupal weight. and pupation rate. However Wesson's salt mixture got the female pupae lighter. Vitamin complex as a substitue for yeast showed a good survivahty in an early larval stage buL pupal weight was lower than that of the individuals reared on the yeast dIet. Also corrugated cardboard was found to be very good for pupation. And the rate of dark~tannmg in pupae was higher as the period of larval development was shorter.
Genomic Recombination of Bombyx mori and Autographa californica Nuclear Polyhedrosis Viruses
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 407~413
Twelve recombinant viruses with wider host range were plaque purified after coinfectian of Autographa cahjornica and Bombyx mOT! NPVs into Sf9 ar BmN-4 cells. Restriction endonucleases analysis of the recombinant's DNAs showed that the recombinatIOn between AcNPV and BmNPV genomes had occurred more than once. When the recombinam RecB-8, derived from BrnN-4 cells, was observed by electron rntcroscopy, the shape of the polyhedron was a regular tetrahedron, and few virions were occluded into a polyhedron.
Species and Seasonal Occurrences of Sericinae, Melolonthinae, and Rutelinae Chafers Captured by Blacklight Traps in Suwon and Chonju
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 414~419
Species and seasonal occurrences of Sencinae, Melolonthinae and Rutelinae chafers captured b by blacklight traps were investigated from 1989 to 1991 in Suwon and Chonju. Numbers of s species captured in Suwon and Chonju were 6 and 6 for Sericinae, 8 and 7 for Melolothinae, 7 a and 8 for Rutelinae, 21 and 21 in total, respectively. Species with more captures from both districts in each subfamily were Maladera orientalis of Sericinae, Holotrichia morosa and H. diomphalia of Melolonthinae, and Anomala corpulenta, and A. rufocuprea of Rutelinae. Adults of t the above five species were captured 1O~20 days earlier in Chonju than in Suwon. H. d diomphalia adults occurred mamly In odd years in Chonju, which is the same pattern as in S Suwon.
Chorion Gene Expression in the Cellular Differentiation and Accumulation of Chorion Protein Synthesis of Silkmoth, Bombyx mandarina(Lepidoptera: Bombycidae). II. Synthesis Programme of Chorion Proteins
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 420~425
The programme of silkrnoth chorion protem synthetIc changes is autonomous i. e.,it is imple I mented WIth normal kinetics by follicles cultured in isolation in a defined tIssue culture medium. On the basis of protem synthetic profiles, 8 stages of chorwgenesis are defined. Detail a analysis of the proteins of chorion of Bombyx mandarina, reveals more than 17 components by eletrophoretic mobility and synthetic kinetics. We have defined three abbreviated synthetlc s stages, based on the pattern of protein synthesized at early, middle, and late synthetic stages

-endotoxins produced by newly isolated Bacillus thuringiensis NT0423
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 426~432
Thirteen isolates of Bacillus thunngiensls producing parasporal mclusions, obtained from 45 samples of dust and soil of sericultural tarms in Kyeong-ki province, were exammed for their toxicity against larvae of Lepidoptera, Dipwra and Coleoptera. Of these isolates, Bacillus f thuringiensis NT0423 was toxic to bath Lepidoptera, and Dipteran larvae. NT0423 showed that the
values against the Lepldaptora, Plutella macuhpennis and the Diptera, Culex pipiens were
CFU/ml, respectively. The tYPlcal bipyramldal crystals produced by NT0423 composed of protoxms of 130-140kDa encoded by one or more plasm mid-horne genes. Also, plasmid DNA analysis indicated Lhat this isolate has 9 plasmids which d differ with reported several B. thuringiensis strains.
Taxonomic Study on Cyclamen Mite (Phytonemus pallidus) and Broad Mite (Polyphagotarsonemus latus)
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 433~439
Morphological characteristics and taxohomy of the two most important Tarsonemid mutes in agriculture, cyclamen mite (Phytonemus pallidus (Banks), 1899) and Broad mite (Polyphagotarsonemus lalus Banks, 1904) are described and drawings of ventral and dorsal views of females and males of each species are provided. Cyclamen mite was collected from fatsia japonica, and Broad mite was collected from Capcicum annuum, Rhododennon schlippenbachil, impatrens sulianti, Ilex serrata, and Fraxinus rhynchophylla.

Effects of Methoprene on Embryo Development in the Gypsy moth, Lymantria dispar
Korean journal of applied entomology, volume 32, issue 4, 1993, Pages 450~456
We investigated effects of a topical treatment of methoprene(0.5-5.0
/egg), a juvenLle horm mane analogue, on embryo development in the gypsy moth, Lymantri
dispar. Methoprene lowered egg hatching rate, and also reduced the mean wet weights of hatched 1st instar larvae w with the most effect shown at the highest concentration. The differences in protein(p < 0.01) and carbohydrate(p < 0.05) contents between control and methoprene(5
/ egg) treatment g groups were observed during embryo development.
