Insecticide resistance in the German cockroach, Blattella germanica (L.), is a significant challenge affecting pest management professionals worldwide. The use of gel baits against German cockroaches has become a popular option in Asia. However, recently, there were anecdotal reports that the field ...

Combinations of bait and spray were tested against susceptible and field-collected German cockroaches, Blattella germanica. In exposure tests, residual deposits of all sprays were lethal to a susceptible strain, but pyrethrin and certain pyrethroid sprays were repellent in choice boxes. Indoxacarb b...

The DDT, deltamethrin, and malathion susceptibilities of five tropical bed bug (Cimex hemipterus) strains, and their resistance mechanisms were investigated using synergism studies and detection of kdr mutations. All C. hemipterus strains showed high resistance to DDT and deltamethrin and moderate t...

Pest identification and monitoring are essential components in an IPM program. In industrial food manufacturing facilities, pest management professionals monitor insect numbers with glue traps using UV- attraction or sex pheromone. Each trap will be collected and closely examined to identify and cou...

The German cockroach, Blattella germanica (L.) is an important urban insect pest world-wide. Heavy reliance and frequent usage of residual insecticides have led to the development of insecticide resistance in the German cockroach. Bait formulations containing fipronil and indoxacarb are excellent re...

In this study, we examined the resistance status of six field-collected strains from Singapore to eight insecticides, as well as the resistance of the parental through F5 generations after they were selected with indoxacarb bait. All strains showed no resistance to acetamiprid (0.7–1.9x), imidaclopr...

Worldwide, there are many reports of pyrethroid resistance in bed bugs (Cimex spp.). Previous studies on the Common bed bug, Cimex lectularius L., have identified two mutations (V419L and L925I) in the voltage-gated sodium channel (VGSC) gene responsible for knockdown resistance (kdr). However, noth...

Choice experiments determined sucrose bait base preference by using laboratory colonies of 10 species of urban pest ants, namely Monomorium pharaonis (L.), Monomorium floricola (Jerdon), Monomorium destructor (Jerdon), Monomorium orientale Mayr, Tapinoma indicum (Forel), Tapinoma melanocephalum (Fab...

Questionnaire-based surveys of homeowners revealed that ants were the most economically important and abundant household pest after mosquitoes and cockroaches in Malaysia. Twenty-five species of ants were found indoors and outside buildings; all species nest outdoors except Monomorium pharaonis, Mon...

Structure-infesting ants are an important group of insect pests in many parts of the world, particularly in residential premises, food outlets, and factories. In Malaysia, it is gradually becoming a major problem especially in urban settings (Lee et al., 1999; Lee and Robinson, 2001). Currently, ant...

The Pharaoh ant, Monomorium pharaonis (L.) is an important pest ant species in many parts of the world. Knowledge and understanding of feeding behavior of this species are essential to the success of baiting. Transfer of a toxicant in a bait to kill a targeted colony depends on the ability of the nu...
