Foraging, recruitment and emigration inMegaponera foetens (Fab.) (Hymenoptera: Formicidae) from the Nigerian Guinea Savanna
Regional differences in foraging and recruitment in the species thoughout the African savannas are compared, and it is confirmed that the scout ant also guided the columns of ants to the termites.
Predation by Megaponera foetens (Fabr.) (Hymenoptera: Formicidae) on termites in the Nigerian southern Guinea Savanna
It is concluded that factors including termite abundance,termite foraging regimes and seasonality, termite biomass and the reactions of the ants to the termites and their products are involved in successful predation of termites by Megaponera.
Pyrethroid resistance monitoring in European populations of pollen beetle (Meligethes spp.): a coordinated approach through the Insecticide Resistance Action Committee (IRAC).
Pyrethroid-resistant beetles dominate in Western and Central Europe and are becoming established in the North and East, the main oilseed-rape-growing areas of Europe.

Sulfoxaflor was largely unaffected by existing cases of neonicotinoid resistance in B. tabaci and T. vaporariorum, and its lack of cross-resistance indicates that sulfoxflor is a valuable new tool for the management of sap-feeding pests already resistant to established insecticide groups.
MANAGEMENT OF MEALYBUG, PHENACOCCUS SOLENOPSIS TINSLEY IN COTTON WITH A NEW SAP FEEDING INSECTICIDE "SULFOXAFLOR"
Sulfoxaflor can be considered as a very good alternative tool to manage P. solenopsis in cotton by providing a high level of control at 3-10 days after application at rates of 25-50 gai/ha.
Development of a monitoring trap for the olive fly, Dacus oleae (Gmelin) (Diptera: Tephritidae), using a component of its sex pheromone as lure
In studies in an olive grove near Granada, Spain, a 25-mg spiroacetal lure used with a vertical yellow trap gave catches of males of D. oleae which were four times as great as those in delta traps with the same lure or in unbaited yellow traps.
Alkylpyrazines in ponerine ants: Their presence in three genera, and caste specific behavioural responses to them in Odontomachus troglodytes
In O. troglodytes caste-specific behavioural differences were found between males and workers in response to gland equivalent quantities of their pheromones, whereas the fragile males retreated from the alkylpyrazines whereas the workers were attracted to and attacked the peromone source.
Foraging, recruitment and predation by Decamorium uelense (Sanstchi) (Formicidae: Myrmicinae) on termites in Southern Guinea Savanna, Nigeria
A scout ant searches for foraging termites and returns to the nest where it recruits a column of 10–30 ants which attack and immobilize the termites, and a mass recruitment phase is then instigated, with larger numbers of ants retrieving the prey.
COMPARATIVE EFFICACY OF SULFOXAFLOR AGAINST COTTON LEAFHOPPER, AMRASCA DEVASTANS (DISTANT) (CICADELLIDAE: HOMOPTERA) UNDER FIELD CONDITIONS OF PUNJAB AND SINDH
Sulfoxaflor proved as an excellent new tool for managing the most destructive pest of cotton in Pakistan and demonstrated very robust short-term and residual activity when applied @ 25-50 g a.i.i per hectare.
Quinoxyfen perturbs signal transduction in barley powdery mildew (Blumeria graminis f.sp. hordei).
RT-PCR profiles of signal transduction genes, recorded during wild-type germling morphogenesis, reveals that quinoxyfen alters the accumulation of Protein Kinase C, pkc-like and catalytic subunit of protein Kinase A transcripts, which suggests that resistance bypasses host recognition signals.
