Alkyl and aryl neoalkanamides with a total carbon number between 11 and 14, or within a molecular weight range between 185 and 227, were highly effective repellents of male German cockroaches, Blattella germanica (L.). Comparison with known repellents showed that members of this unique family of secondary amides are among the most effective and long-lasting repellents of cockroaches examined to...

The long-term costs and efÞcacy of two treatment methodologies for German cockroach, Blattella germanica (L.), control were compared in the public housing environment. The “traditional” treatment forGermancockroaches consistedofmonthlybaseboard andcrack andcrevice treatment (TBCC) by using spray and dust formulation insecticides. The integrated pestmanagement treatment (IPM) involved initial va...

Field studies were conducted to compare the performance of Goliath® Cockroach Gel (fipronil) and a spray treatment of Cislin Residual Insecticide (deltamethrin). These were carried out in Sydney, NSW, Australia against Blattella germanica (L), and Townsville, Queensland, against a mixed population of Periplaneta americana (L.) and Periplaneta australasiae (L). In both studies fipronil (0.05% AI...

We studied the efficiency and toxicity of new insecticide “GET Dry” (active ingredients alpha-cypermethrin imidacloprid). The target as acute residual impact was studied, when agent applied against tropic bed bugs (Cimex hemipterus), German cockroach (Blatella germanica), false stable flies (Musca domestica) larvae leather beetles (Attagenus smirnovi). demonstrated strong effect (about 100%), c...

A field study on cockroach species diversity, and influence of sanitation on infestation level, was conducted on six different locations (four apartment settings [Tmas, Bmaung2, Relau and Kmelayu], a residential slum setting [Sg Batu] and a terrace houses setting [Bmaungl]) in Penang Island, Malaysia. A total number of 192 residential premises were sampled and 3,289 cockroaches, consisting of 1...
