Stored product pests are not typically called urban pests, however because of urbanisation and the concentration in towns and cities of the population world-wide, silos and other types of grain warehouses and mills are also nearer to cities or are even built right into the cities. One of the greates...

The intrinsic activity of combinations of methoprene and chlorfluazuron and methoprene and fipronil was determined against larval cat fleas, Ctenochephalides felis (Bouché). Methoprene synergized the activity of the IGR chlorfluazuron and the adulticide fipronil. The LC50s of chlorfluazuron, fiproni...

New bed bug control products, methods and Codes of Practices have been introduced, but it is likely that until we have a novel insecticide molecule and their formulations to which the bed bugs are fully susceptible, we cannot achieve appropriate results. Following a series of individual laboratory t...

Several ant species have association to human structures in Brazil and their presence promotes problems such as contamination of food, damage to electronic appliances, and allergies due to the their venom. The objective of this work was to evaluate the effects of a methoprene-based bait against diff...

Widespread resistance to conventional residual neurotoxic insecticides such as pyrethroids is likely to be a major factor in bed bug infestations. To identify an insecticide with an alternative mode of action that is effective against the bed bug, the juvenile hormone analogue (S)-methoprene, was ev...

Climatic changes, tourism and travel, intensive product deliveries, especially of tropical plants, all contribute to the growth of ant infestations in Europe. These rapidly adopting ant species might need to be more thoroughly learnt and understood and possibly new, inventive eradication systems be ...

The Pharaoh’s ant, Monomorium pharaonis (L.) is an important species in the urban environment. This paper discussed the performance of a new bait formulation containing S-methoprene. Discussions are made on various laboratory experiments (in Budapest, Hungary and Penang, Malaysia) and field trials i...

Efficient control and eradication of Pharaoh’s ant is a difficult task for PCOs mostly due to the fact that several queens live in a nest, all of which can not be killed with traditional methods. PROTECT B Pharaoh’s ant killer bait is a special ready-to-use formulation that contains an insect growth...

The history of natural and synthetic bioanalogues of insect juvenile hormone (JH), juvenoids is more than 40 years old. The first JH-active lipid extracts prepared from the cecropia moths in 1956. The first JH-active was an isoprenoid farnesol isolated in 1961, then “pseudojuvenilizing” or JH-mimeti...

Pyriproxyfen, a synthetic analogue of the juvenile hormone of insects, has been used in the form of 0.5% granules (Sumilarv, Sumitomo, Japan) against preimaginal stages of house flies and mosquitoes for suppressing their quality. As the main condition of the experiment was to use strictly equalized ...

Mosquito-borne disease is an increasing concern in Australia. Endemic malaria has been eradicated but up to 1,000 infections are imported annually and local cases occur occasionally in the northeast, where local Dengue infections are reported annually and Japanese encephalitis virus has been introdu...

Currently 3 insect growth regulators either are or soon will be labelled as on-animal treatments to control fleas on pets and livestock. These chemicals, fenoxycarb, methoprene and pyriproxyfen are juvenile hormone mimics that disrupt embryonic and post-embryonic development when present during cert...
