目的了解海军某编队害虫种群构成、密度情况,为现场防治提供参考。方法以编队舰船内厨房、餐厅、居室、库房和轮机附近舱室作为调查点,采用粘捕及现场查看的方式进行调查,并结合舰船实际进行分析。结果共捕获蟑螂741只,其中德国小蠊占94.87%,澳洲大蠊占3.91%,美洲大蠊占1.21%。蟑螂主要分布于厨房和轮机附近舱室,其次为居室,餐厅和库房最少,侵害率存在显著差异(χ2=84.322,P<0.001)。舰船在海上航行期间,共捕获蝇类45只,其中家蝇32只,果蝇13只,数量较少。另外在舰船常温干货库内发现了赤拟谷盗、锯谷盗、米象、印度谷螟、烟草甲虫等仓储害虫的成虫或幼虫。结论编队内舰船蟑螂、仓储害虫危害严重,建议采取综合防治措施。
Objective To understand the population composition and density of a certain formation pest in the Navy and provide a reference for on-site prevention and treatment. Methods Taking the cabins of kitchens, restaurants, living rooms, warehouses and turbines as the investigation points in the fleet of ships, the investigation was carried out by means of sticky catch and on-site inspection, and the actual ship analysis was conducted. Results A total of 741 cockroaches were captured, of which, Blattella germanica accounted for 94.87%, Australian cockroach accounted for 3.91% and American cockroach accounted for 1.21%. The cockroaches were mainly distributed in the cabin near the kitchen and the turbine, followed by the living room, the least restaurant and the warehouse, and the infringement rate was significantly different (χ2 = 84.322, P <0.001). During the sea voyage, a total of 45 flies were captured, of which 32 were housefly and 13 were fruit flies, with a small number. In addition, the adult or larvae of storage pests such as red tarragon, sawtooth booby, rice elephant, Indian rice stem borer and tobacco beetle were found in the normal temperature dry cargo warehouse of the ship. Conclusion The formation of cockroaches in ships and warehousing pests are seriously endangering. It is suggested that comprehensive prevention and control measures should be taken.
