植物源甘油酯及其减药组合对3种柑橘害虫的药效评价

为探索植物源甘油酯及其减药组合对3种柑橘害虫的防效和减药增效作用,以柑橘红蜘蛛、柑橘粉虱和康氏粉蚧为防治对象,测试了植物源甘油酯及其与联苯肼酯的减药组合对柑橘红蜘蛛的防控效果,植物源甘油酯及其与啶虫脒的减药组合对柑橘粉虱、康氏粉蚧的防控效果。结果表明,将植物源甘油酯作助剂,与减少50%用量的联苯肼酯、啶虫脒混用,均可达到与常规剂量的防效,甚至部分处理防效略高于常规剂量;单独喷施2次植物源甘油酯100倍液和200倍液对柑橘粉虱的防效与常规剂量的啶虫脒防效均无显著差异,但喷施1次植物源甘油酯200倍液对柑橘红蜘蛛和柑橘粉虱的防效较差;植物源甘油酯对康氏粉蚧无效。因此,单独使用植物源甘油酯防控柑橘红蜘蛛和柑橘粉虱时,建议采用200倍液喷施2次,推荐将植物源甘油酯与减少50%用量的联苯肼酯或啶虫脒混配使用。

Heartworm in dogs in Canada in 1984

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal.

Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection.
