Seasonal activity and bait preferences of the Argentine ant (Hymenoptera: Formicidae).
Foraging by workers of Argentine ants, Linepithema humile (Mayr), in California was seasonal, with peak activity occurring from June to October. Workers foraged throughout the other cooler months,… Expand
Delayed Toxicity as a Critical Factor in the Efficacy of Aqueous Baits for Controlling Argentine Ants (Hymenoptera: Formicidae)
Abstract Boric acid, imidacloprid, and thiamethoxam in sucrose aqueous baits had different delayed toxicities to worker Argentine ants, Linepithema humile (Mayr). The concentrations required to… Expand
Influence of repellency on the efficacy of blatticides. I. Learned modification of behavior of the German cockroach.
Devices were developed for determining the behavior of the German cockroach, Blattella germanica (L.), when it is given the ‘choice’ of entering or avoiding areas that would normally be attractive,… Expand
Control of American cockroaches (Dictyoptera: Blattidae) in sewers.
Baits, dusts, and aqueous sprays were applied to sewer shafts to control American cockroaches, Periplaneta americana (L). Boric acid and hydramethylnon baits failed to provide consistent control… Expand
Pest Management of Argentine Ants (Hymenoptera: Formicidae)
Control of Argentine ants, Linepithema humile (Mayr), around structures in urban settings requires an extensive and thorough use of existing registered sprays and baits. Barrier sprays must be thor...
Comparative water relations and temperature sensitivity of cockroaches
1. 1. Cuticular permeability (CP) and critical thermal maxima (CTM) were determined for ten cockroach species representing three families. 2. 2. The CP ranged from 53.7 μg/cm2/hr/mm Hg for… Expand
Relationship between insecticide resistance and performance in choice tests of field-collected German cockroaches (Dictyoptera: Blattellidae).
Topical application (LD) and time-mortality response (LT) methods were used to determine resistance levels of field-collected strains of the German cockroach, Blattella germanica (L.). LD50s for… Expand
Directed Sprays and Liquid Baits to Manage Ants in Vineyards and Citrus Groves 1
Chemical treatments were evaluated for efficacy against spe- cific ant pests in two perennial field crop systems. A directed spray of Lorsban applied in grape vineyards resulted in significant… Expand
Predation of the endangered California Least Tern, Sterna antillarum browni by the southern fire ant, Solenopsis xyloni (Hymenoptera, Formicidae)
The southern fire ant, Solenopsis xyloni (McCook), is capable of breaching and foraging on eggs of Coturnix Quail, Cotumix coturnix (L.), which are similar in size and egg shell thickness to… Expand
