摘要

The Khapra Beetle (KB), Trogoderma granarium Everts, of family Dermestidae, is considered to be one of the most serious, destructive and formidable pests of stored grain, grain products and seeds in the world. KB is classified as a quarantine pest, not known to occur in Singapore. Singapore imports large quantities of stored grain commodities, rice, cereals and spices to ensure adequate supply of these commodities for local consumption, trans-shipment trade as well as repacking for export. KB is reported to be endemic in the countries listed in the CABI CPC 2014 and Singapore imports a variety of commodities from 11 of these countries. KB infestation in Singapore would pose a serious threat to our grain and stored products industry, which are of economic importance for both domestic and foreign markets. Detection survey for Trogoderma granarium has been on going in Singapore since the 1990s with the use of commercial pheromone traps in local warehouses and commodity sampling. This findings of the detection survey conducted from 2005 to 2012 were reported here. A total of 2326 KB specific pheromone traps had been installed and monitored in 5 local warehouses during this period and no khapra beetle had been detected. In addition, a total of 354 imported commodities (rice, various types of spices, dried fruits, nutmegs, etc.) sampled from local warehouses revealed absence of khapra beetle. Only common stored product pests such as Tribolium sp, Orphinus sp, Lasioderma serricorne, Carpophilus sp and Sitophilus sp have been detected. The status of Trogoderma granarium in Singapore is Absent: no pest record (confirmed by survey). The situation is continuously being monitored with pheromone trapping and commodity sampling.

During the continuation of the survey from 2015 to 2020, 332 combined samples from pheromone traps and commodity sampling from local warehouses yielded negative result for Trogoderma granarium and Prostephanus truncates. (Survey for P. truncates has been added in 2015). Rice and various types of spices were among the imported commodities being sampled. In addition, a total of 1,098 re-export commodities mainly wheat products, cocoa products, spices were sampled and tested to be free from KB.

The updated status of Trogoderma granarium in Singapore as of end 2020 remained as Absent: no pest record(confirmed by survey).
