| 中文摘要 | 鱗翅目夜蛾科(Lepidoptera: Noctuidae)秋行軍蟲(Spodoptera frugiperda(J. E. Smith, 1797))原產於北美洲南部,文獻紀載可作為其寄主的植物多達76科,354種以上,現已擴散到全球,深受各國重視。此害蟲於2019年入侵臺灣,並有危害多種作物的報導。雖然目前在田間以危害禾本科(Poaceae)玉米(Zea mays L.)和高粱(Sorghum bicolor(L.)Moench)為主,但此害蟲對茄科(Solanaceae)的番茄(Solanum lycopersicum L.)、菸草(Nicotiana tabacum L.)與番椒(Capsicum annuum L.)等作物亦具危害潛力,而其中番茄在臺灣甚具經濟價值。故本研究選擇包含商業種植之大果(黑柿)和小果(美女)番茄品種,取其葉片餵食玉米品系(corn strain)秋行軍蟲幼蟲,再以取食實驗室保存(由國立嘉義大學植物醫學系植物細菌研究室提供)之番茄(L390)品種、硬質玉米(台農一號)葉片和人工飼料之族群作為對照,進行生活史觀察比較。結果顯示,取食黑柿番茄葉片之個體皆無法完成生活史,其平均幼蟲期分別為取食美女番茄葉片組為29.8日、L390組為29.2日、取食硬質玉米葉片者為17.4日和取食人工飼料者為19.7日。兩性生命表分析,內在增值率(r)分別為為取食美女番茄葉片者為0.0338 day-1、L390葉片者為0.1030 day-1、硬質玉米葉片者為0.1490 day-1與人工飼料者為0.1784 day-1。本研究結果顯示,受試秋行軍蟲對番茄葉片的寄主適應性較低,其中黑柿品種試驗組之幼蟲皆無法存活,而取食美女品種與L390葉片之族群雖可完成生活史,但各項族群參數皆低於取食玉米葉片與人工飼料者,故於臺灣番茄田間當前對此害蟲之防治可暫以田間監測為主。本研究主要以不同品種番茄葉片為食物飼育玉米品系秋行軍蟲幼蟲並建立相關生物學資訊,所得資料為此害蟲整合管理(IPM)策略擬定之重要參考。 |
| 英文摘要 | Fall armyworm (FAW)(Spodoptera frugiperda (J. E. Smith, 1797))(Lepidoptera: Noctuidae) is an important agricultural pest. It has rapidly spread through Asia and Oceania from its native distribution of tropical and subtropical North America and has been recorded on 354 plant species from more than 76 families. FAW invaded Taiwan in 2019 and has significantly reduced crop yield of maize (Zea mays L.) and sorghum (Sorghum bicolor (L.) Moench)). FAW also feeds on leaves of some crops of Solanaceae, such as tomato (Solanum lycopersicum L.), tobacco (Nicotiana tabacum L.) and pepper (Capsicum annuum L.). Tomato crops are widely planted and have a high economic value in Taiwan. In this study, we tested whether two commercial tomato varieties, Rosa and FMTT593, are suitable host plants for FAW. In addition, leaves of the experimental tomato line (L390), maize (Tainong No. 1) and artificial diets were used as controls to do life history experiments. The developmental periods were 29.8 days for population fed on Rosa leaves, 29.2 days for population fed on L390 leaves, 17.4 days for population fed on maize leaves, and 19.7 days for population fed on artificial diets. The larvae fed on FMTT593 leaves did not survive. All collected data were analyzed by using TWOSEX-MSChart and the results show that the intrinsic rate (r) was 0.0338 day-1 for Rosa, 0.1030 day-1 for L390, 0.1490 day-1 for maize, and 0.1784 day-1 for artificial diet. We conclude that tomato is not a suitable host plant for FAW, even though individuals can feed on the leaves and can complete their life cycles on L390 and Rosa. This study contributes to the development of an integrated pest management (IPM) strategy to manage damage caused by FAW in Taiwan. |
