Abstract

C. viridivittatus, citrus weevil distributed throughout the coffee maker and Andean region of Colombia. The larvae feed on roots and adults on leaves and flowers. On three citrus farms of the Valley were isolate and evaluated fungi and entompathogenic nematodes M. anisopliae and B. bassiana and Steinernema sp. and Heterorabditis sp.on larvae of C. viridivittatus 26, 36, 48 and 53 days of age. In 120 from 132 soil samples were found 21 fungi and none nematodes. Commercial B. bassiana B9 and B10 caused 100 % adult mortality in a time of 4.3 and 4 days. M. anisopliae M6 y M7 caused 94 % and 97 % of mortality to the 4.3 and 5 days. Steinernema sp. UNS09 caused 65 % of mortality on larvae of 48 and 53 daysof age, seven days later. No were differences between UNS09 Steinernema and Heterorhabditis UNH16.Steinernema sp. UNS09 caused 85.7 % of mortality on 53 days larvae and 81.9 % and 81.1 % to larvae of 36 and 26 days. Heterorhabditis sp. UNH16 killed larvae of 36, 26 and 56 days was 79 %, 81 % and 75.4 % seven days later. In conclusion, fungi and nematodes can be an alternative to management of C. viridivittatus larvae.

柑橘相关昆虫病原及其对Compsus viridivittatus guerin - meneville(鞘翅目:Curculionidae)的致病性

C. viridivittatus，柑橘象鼻虫，分布于哥伦比亚的咖啡壶和安第斯地区。幼虫以根为食，成虫以叶和花为食。在3个柑桔场对26、36、48和53日龄的绿僵菌(C. viridivitatus)幼虫分别进行了真菌和昆虫病原线虫的分离鉴定。在132份土壤样品中，120份中发现21种真菌，未发现线虫。商业球孢白僵菌B9和B10的成虫死亡率分别为100%和4.3 d和4 d。绿僵菌M6和M7对4.3和5 d的致死率分别为94%和97%。7 d后，对48和53日龄幼虫的死亡率为65%。UNS09 steinerma与Heterorhabditis un16间无差异。对53日龄幼虫的死亡率为85.7%，对36日龄和26日龄幼虫的死亡率分别为81.9%和81.1%。7 d后，异habditis sp. un16对36、26和56 d幼虫的杀虫率分别为79%、81%和75.4%。综上所述，真菌和线虫可以作为一种替代方法来管理毒蛾幼虫。

期刊介绍： The journal Ciencia y Tecnología Agropecuaria (Science and Agricultural Technology) is a four-monthly scientific publication edited since October 1996 by the Corporación Colombiana de Investigación Agropecuaria - Agrosavia. The journal publishes articles on diverse thematic areas typical of the agricultural sector (multidisciplinary), written in Spanish or English, especially from Latin American and Caribbean researchers. The contributions that apply for the journal must be original and unpublished. The articles are reviewed by national and international peers (peer review). The journal is non-commercial and open access, this means that it doesn’t charge for the reception and/or publication of articles in both, its printed and digital version. The journal is aimed at the scientific community of the agricultural sector in Latin America and the Caribbean.
