Red imported fire ant (Hymenoptera: Formicidae) control with a corn grit bait of fenoxycarb without soybean oil.

Microencapsulated Bait: Does It Work With Red Imported Fire Ants, Solenopsis invicta (Hymenoptera: Formicidae)?

The preference of red imported fire ants, Solenopsis invicta, for microencapsulated (MC) pyriproxifen based corn grit baits (P-bait) was conducted in laboratory and field conditions. A positive correlation between the microencapsulation rate and water tolerance ability of P-bait was observed. A 20% increment of water tolerance ability of P-baits was observed when P-baits were microencapsulated ...

Effect of the Insect Growth Regulator Fenoxycarh on the Ovaries of Queens of the Red Imported Fire Ant (Hymenoptera: Formicidae)

The insect growth regulator, fenoxycarb, ethyl [2-(4-phenoxyphenoxy)ethyl] carbamate, causes retrogression of the ovaries of mated queens of the red imported fire ant, Solenopsis invicta Buren. Fenoxycarb completely suppresses growth of the follicular epithelium, nurse cells, and cytoplasm/yolkplasm. Most developing eggs are resorbed and no new workers are produced. Thus, prolonged exposure of ...

Aggressive interactions between Solenopsis invicta and Linepithema humile (Hymenoptera: Formicidae) under laboratory conditions.

The Argentine ant, Linepithema humile (Mayr), and the red imported fire ant, Solenopsis invicta Buren, are natural agonists in their country of origin. Since the first report of L. humile in California in 1907 its range expanded statewide, displacing native ant species wherever it spread. Since the discovery of established populations of S. invicta in southern California in 1998, it has been re...
