Bionomics of Diamond-back Month, Plutella xylostella(Lepidoptera: Plutellidae) in Southern Region of Korea
Korean journal of applied entomology, volume 30, issue 3, 1991, Pages 169~173
These studies were conducted to investigate overwintering forms and adult population fluctuation in field condition, and life cycle in field-cage condition of diamondback moth, Plutella xylostella (L.). Plutella xylostella overwintered as all the stages of eggs, larvae, pupae and adults in southern region of Korea. The occurrence which adult moths were attracted by light trap at 5-day intervals, reached their peaks in May, mid-June to mid-July, and late September to early November, and fell in late July to mid-September. Under field-cage condition, they occurred 10-11 generations a year and the period of adult emergence from egg was 11-18 days in July and August, 19-23 days in June and September, 28-34 days in April, May and October, and about 50-100 days in other months. And the longevities of adults were 4-11 days in summer, 7-17 days in spring and fall. A number of eggs laid by individual female ranged from 50 to 240. The females laid more eggs in spring and fall than they did in summer. The period of developmental stages under field-cage conditions was 2-3 days for eggs, 7-8 days for larvae and 4-6 days for pupae in July and August; 4-5 days for eggs, 3-12 days for larvae and 6-8 days for pupae in June and September; 6-18 days for eggs, 13-20 days for larvae and 8-14 days for pupae in March, April, May and October; and 12-40 days for eggs, 50-100 days for larvae, and about 20 days for pupae in winter.
Pattern of Ginseng Damage by Korean Black Chafer (Holotrichia diomphalia Bates) in Spring
Korean journal of applied entomology, volume 30, issue 3, 1991, Pages 174~179
Patterns of ginseng damage by larvae of Holotrichia diomphalia Bates in spring were investigated in 3rd year ginseng fields from 1986 to 1990. Ginseng damages were more serious in outer areas than inner areas of ginseng fields, which seemed to be due to nocturnal migration behavior of adult females. Damaged parts of 3rd year ginseng plants due to 3rd instar larvae were top, middle, bottom or whole of main roots, and rarely underground stems. Mean inhabitation depth of 3rd instar larvae were 3.2cm, 5.6cm, 6.6cm and 4.9cm in 1st, 2nd and 3rd year ginseng fields and mugwort fields, respectively. Larval feeding damage of ginseng in spring oc¬curred mainly from mid-May to early July and appeared to decrease temporarily when rainfalls increased.
Biochemical Characteristics of the Granulosis Viruses Proteins of Common Cabbage Worm, Pieris rapae and Pieris brassicae
Korean journal of applied entomology, volume 30, issue 3, 1991, Pages 180~186
This study was carried out to acquire some basic biochemical informations on the granulosis virus(GV) of Pieris rapae and Pieris brassicae. The capsule protein was composed of a single polypeptide with a molecular weight of 30,000 dalton for P. rapae GV and 31,000 dalton for P. brassicae GV. The major amino acids of capsule protein were glutamic acid, aspartic acid and lysine. When the capsule protein was partially digested with trypsin, chymotrypsin, papain or Staphylococcus aureus V8 protease, the digested products of the two viruses showed no difference in electrophoretic mobility. The patterns of the polypeptides of the two virus particle on SOS-polyacrylamide gel showed a little difference in high molecular weight region(over MW 100 kd).
Purification and Pathogenicity of the Granulosis Viruses of Common Cabbage Worm, Pieris rapae and Pieris brassicae
Korean journal of applied entomology, volume 30, issue 3, 1991, Pages 187~195
This study was carried out to acquire some basic biological informations on the granulosis virus (GV) of Pieris rapae and Pieris brassicae. Purified fractions of GV capsules in an sucrose density gradient centrifugation yielded on homogenous and sharp peak without a shoulder. Electron microscopy revealed that GV capsules were mostly ovalglove in shape. P. rapae and P. rapae GV isolated from P. rapae comprised granules(
for P. rapae GV.
for P. brassicae GV) which contained single virus particle. The virus particles were 250-
-73nm for P. rapae GV and 243-250
63-75nm for P. brassicae GV containing a nucleocapsid 225
31nm for P. rapae, 225
29nm for P. brassicae within an envelope. The virulent difference between the two viruses was very small in their virulence for P. rapae larvae showing the
( -log) with 5.5673 for P. rapae GV and 5.8104 for P. brassicae GV. Also the
of the 3rd instar P. rapae larvae against
inoculum was 8.17 days for P. rapae GV and 7.16 days for P. brassicae GV.
Korean Species of the Genus Athrips Billberg (Lepidoptera: Gelechiidae)
Korean journal of applied entomology, volume 30, issue 3, 1991, Pages 196~200
A Species of the genus Athrips Billberg, A. polymaculella sp. nov. is described as new to science and A. adumbratella (Snellen) is reported for the first time from Korea.
Taxonomic Notes on 6 Unrecorded Anthomyiid Flies from Korea (Diptera: Calyptratae)
Korean journal of applied entomology, volume 30, issue 3, 1991, Pages 201~211
A total of 38 species belonging to 19 genera of the Anthomyiidae form Korea are treated. Among them, 1 genus and 6 species are new to Korean fauna.
Pathogenicity of Spodoptera exigua Nuclear Polyhedrosis Virus and Cross Infection of Baculoviruses to the Beet Armyworm, S. exigua (Lepidoptera: Noctuidae)
Korean journal of applied entomology, volume 30, issue 3, 1991, Pages 212~218
Pathogenicity of Spodoptera exigua nuclear polyhedrosis virus (SeMNPV) against the host insect and 8 species of lepidopterous insects and cross infection of baculoviruses to third instar of S. exigua larvae were studied to determine as a biocontrol agent for S. exigua. The median lethal concentrations(
)of the SeMNPV to egg mass was
PIBs/ml and higher than that to the larvae of S. exigua. Mortality of the SeMNPV in third ins tar larvae was more increased than that in first and fifth instar of S. exigua larvae by 1.16 and 4.11 times, respectively. The median lethal times(
PIBs/ml was in the range of 4.25 to 5.04 days. Infectivity of the SeMNPV against eight species of lepidopterous insects was showed only in the host insect, S. exigua. Autographa cali/ornica MNPV, Mamestra barassicae MNPV, and Trichoplusia ni MNPV were cross-infected to third instar of S. exigua larvae among ten of baculoviruses tested.
A Cytoplasmic Polyhedrosis Virus Isolated from the Oriental Tobacco Budworm, Heliothis assulta Guenee (Lepidoptera: Noctuidae)
Korean journal of applied entomology, volume 30, issue 3, 1991, Pages 219~226
A cytoplasmic polyhedrosis virus isolated from the oriental tobacco budworm, Heliothis assulta (HaCPV), was studied on morphology of the polyhedron and virus particles, analysis of viral protein and nucleic acid, and bioassay of the HaCPV to determine the feasibility of application as a microbial control agent. The shape of polyhedron was hexagonal ranging 0.5-3.7
and the virus particles were icosahedral outline measured 55 nm in diameter. Polyhedral protein was composed of a major polypetide of 24.3 Kd and 5 minor components and virus particle had seven polypeptides ranging in 28.0 Kd-133. 6 Kd by the SDS-P AGE. The genome of virus was segmented with 10 double stranded RNA in the total mol. wt. of 18.08 Md ranging in 0.65 Md -2.79 Md. The
values of the HaCPV to the 3rd instar of H. assulta larvae were calculated to
values in the concentration of
was 16.4 days.
