  • 과수에서 초기 해충종합관리(IPM) 모형은 응애류 종합관리를 기반으로 수립되었다고 할 수 있다. 근간은 기존 방제체계인 화학적 방제와 호환적인 포식성 이리응애 천적을 접목한 생물적 방제가 작동하는 것에 있었다. 이후로 생태계 종다양성과 해충 개체군 변동과의 상호작용에 대한 가설과 기작은 과수 생태계에서 응애류 중심의 해충관리에 대한 더 넓은 이해의 폭을 제공하였다. 생태계의 원리를 바탕으로 환경의 개변 또는 변경을 통한 생물적 방제와 해충관리는 농생태공학적 개념으로 발전하고 있다. 특히 응애류 해충의 관리에 있어서는 재배환경의 변화에 따라 관련된 천적의 다양성이 역동적으로 변동되어 작동하고 있으며, 식식성 응애류의 종 구성도 과원관리 환경에 따라 변화를 보이고 있다. 본 원고에서는 사과 IPM의 근간이 되었던 응애류 생물적 방제를 고찰하면서 생태공학적 측면에서 종다양성과 해충관리, 포식성 응애류 종다양성과 응애류 관리, 환경과 응애류의 종 구성 변동 원리에 대하여 기존 사례연구를 바탕으로 재조명하고, 향후 우리나라에서 사과원 응애류의 생물적 방제 전략을 제시하고자 한다.

  • In nature, plant diseases, insects and parasites (hereafter called as "pest") must be co-survived. The most common expression of co-survival of a host crop to the pest can be tolerance. With tolerance, chemical uses can be minimized and it protects environment and sustains host productivity and the minimum pest survival. Tolerance can be applicable in all living organisms including crop plants, lifestocks and even human beings. Tolerant system controls pest about 90 to 95% (this pest control system often be called as horizontal or partial resistance), while the use of chemicals or selection of high resistance controls pest 100% (the most expression of this control system is vertical resistance or true resistance). Controlling or eliminating the pests by either chemicals or vertical resistance create new problems in nature and destroy the co-survial balance of pest and host. Controlling pests through tolerance can only permit co-survive of pests and hosts. Tolerance is durable and environmentally-friend. Crop cultivars based on tolerance system are different from those developed by genetically modified organism (GMO) system. The former stabilizes genetic balance of a pest and a host crop in nature while the latter destabilizes the genetic balance due to 100% control. For three decades, the author has implemented the tolerance system in breeding maize cultivars against various pests in both tropical and temperate environments. Parasitic weed Striga species known as the greatest biological problem in agriculture has even been controlled through this system. The final effect of the tolerance can be an integrated genetic pest management (IGPM) without any chemical uses and it makes co-survival of pests in nature.in nature.

  • In India, mulberry (Morus spp.), the sole food plant of the silkworm, Bombyx mori (Linn.), is prone to infestation by the pink mealybug, Maconellicoccus hirsutus (Green). Infestation by this pest causes apical shoot malformation, popularly known as 'tukra'. Occurrence of tukra causes an appreciable reduction in leaf yield and quality, leading to low silkworm cocoon productivity. For management of M. hirsutus (Tukra), an IPM package comprising mechanical, chemical and biological measures was demonstrated in the mulberry gardens of five Government Silk Farms in Mysore District (Karnataka, India) during 1995-96. A suppression of 76.0% in tukra incidence and 90.19% in mealybug population was recorded by employ the IPM package which led to an estimated 4,000 kg recovery in leaf yield/ha/year. The impact of IPM package in the management of M. hirsutus, the role of biocontrol agent (Cryptolaemus montrouzieri Muls.) in pest suppression and the cost-benefit analysis of the IPM package are discussed.

  • Bell pepper is an economically important crop worldwide; however, production is restricted by a number of fungal diseases that cause significant yield loss. Chemical control is the most common approach adopted by growers to manage a number of these diseases. Monitoring for the development to resistance to fungicides in pathogenic fungal populations is central to devising integrated pest management strategies. Two fungal species, Fusarium incarnatum-equiseti species complex (FIESC) and Colletotrichum truncatum are important pathogens of bell pepper in Trinidad. This study was carried out to determine the sensitivity of 71 isolates belonging to these two fungal species to fungicides with different modes of action based on in vitro bioassays. There was no significant difference in log effective concentration required to achieve 50% colony growth inhibition ($LogEC_{50}$) values when field location and fungicide were considered for each species separately based on ANOVA analyses. However, the $LogEC_{50}$ value for the Aranguez-Antracol locationfungicide combination was almost twice the value for the Maloney/Macoya-Antracol location-fungicide combination regardless of fungal species. $LogEC_{50}$ values for Benomyl fungicide was also higher for C. truncatum isolates than for FIESC isolates and for any other fungicide. Cropping practices in these locations may explain the fungicide sensitivity data obtained.

  • Hexane extract of Porteresia coarctata (Roxb.) exhibits a toxic effect on the tissues of Spodoptera litura (F) while fed at the dose of 1000 and 2000 ppm thoroughly mixing with castor leaves (Ricinus communis L) after dissolving in DMSO at late fourth instar whereas only DMSO treated castor leaves were fed to control group. The larvae were put to rear at $28^{\circ}C{\pm}1^{\circ}C$, $76{\pm}4%$ R.H. under 12 L + 12 D photoperiodic regime. In test group insects substantial reduction of protein and DNA content was marked in fat body and midgut tissues compared to DMSO treated control group. The significant biochemical alterations in the midgut tissues and fat body of test group insects indicate the insecticidal property of the said plant extract that could be tested in facilitating the phenomenal stride in Integrated Pest Management.

  • 포식성 천적 칠레이리응애에 대하여 8종 살충제들의 감수성을 검정하였다. 칠레이리응애 암컷성충은 실험약제들의 처리 168시간 후에 78-92%의 개체들이 생존하였으며, 무처리 암컷성충에 비해 62.6-93.4%의 산란수를 보였으며, 산란된 난들의 부화에 영향이 없었다. 실험약제들은 칠레이리응애 난의 부화와 약충의 생존율에 큰 영향이 없었다. 칠레이리응애의 발육태들은 실험약제들이 처리된 잎 절편에서 생존율에 큰 영향을 받지 않아, 98-100%의 개체들이 성충태에 도달하였다. 이상의 결과로 보아, 실험약제들은 해충종합관리 체계에서 칠레이리응애와 함께 활용할 수 있을 것으로 생각된다.

  • One major constraint in the development and implementation of a successful and cost-effective area-wide integrated pest management (AW-IPM) programme with a SIT component for Bactrocera oleae (Diptera: Tephritidae) is the ability to produce a large number of high quality mass-reared individuals. The aim of this study was to develop a more efficient and practical egg collection system in an attempt to improve the mass-rearing of this species. The following basic parameters were examined: egg production per female, egg hatch, pupal recovery, pupal weight, adult emergence and percentage of fliers. Three different strains (Israel wild-type, France wild-type, and Greece laboratory) were tested and each strain was evaluated for six generations. Female flies of the Israel strain produced significantly more eggs per female than the other two strains, but egg hatch was significantly lower. Egg hatch of the France wild type and the Greece laboratory strain was similar. For all other parameters, there was no significant difference between strains; however, there was a significant generational effect for all parameters observed. As a result of this study, a protocol was developed for the mass-rearing of this species that included the use of large adult holding cages that could house up to 96,000 flies per cage. The newly developed method of egg collection using a flat wax panel as one of the sides of an adult holding cage proved to be cost-effective, efficient, making colony growth easier for industrial mass-rearing.

  • This study was performed to develop an information processing system for the sound conservation of soil and groundwater resources. The system contains the geographic spatial information system(GSIS), and the numerical model of groundwater flow and contamination. Numerical models (MODFLOW, MOC3D, MT3D, PMPATH, PEST, UCODE) and GSIS(ArcView) were integrated for the construction of an integrated management system of subsurface environment. The developed system was applied to the management of three mineral water companies located in clean mountain area. The impact of pumping over the overall catchment basin was modeled using the developed system for the decision of future management criteria.

  • 국제 무역량 증가와 기후변화에 따라 아열대성 해충이 온대지역으로 침입하는 사례가 늘고 있다. 과실파리과는 초파리과와 더불어 두 과실파리 분류군 가운 데 하나로 약 5,000 종 이상이 포함되어 있다. Anastrepha, Rhagoletis, Ceratitis 및 Bactrocera 속에 속한 일부 과실파리류가 높은 침입력으로 여러 온대 지역의 과실과 채소류에 막대한 피해를 일으키고 있다. 본 종설은 이들 과실파리류들의 침입과 정착을 억제하는 기술이 비교적 잘 개발되어 적용된 Bactrocera 속에 속한 해충류를 중심으로 고찰하였다. 이들 과실파리류에 대해 많은 방제 기술이 개발되었지만, 효율적인 종합해충관리 프로그램 개발이 아직 널리 정착되지 않고 있다. 이에 본 종설은 과실파리를 방제하는 여러 기술을 설명하고, 이 가운데 아열대 군도에서 실시된 종합해충관리의 성공사례를 소개한다. 아울러 국내에 큰 피해를 주는 주요 과실파리의 발생생태와 방제기술도 정리하였다.
