The red imported fire ant,Solenopsis invicta Buren, was identified as a key predator of the boll weevil,Anthonomus grandis Boheman. Although key factor analysis does not guarantee that the key factor is the causative agent, the evidence of boll weevil mortality was so clear that the fire ant could be identified as causing the mortality. Ant predation on immature boll weevils during the summer of 1981 averaged 84%. When this predation was combined with other natural mortality factors, the weevil… 

Naturally-occurring biological control of the boll weevil [Col.: Curculionidae]

Red imported fire ants,Solenopsis invicta Buren, are effective predators of the boll weevil,Anthonomus grandis Boheman, in east Texas cotton fields, and unnecessary applications of insecticides should be eliminated.

Impact of the red imported fire ant upon cotton arthropods

Inclusion/exclusion field experiments demonstrated that the red imported fire ant, Solenopsis invicta Buren, did not affect the abundance of 49 groups of insects and spiders collected in pitfall traps, but arthropod diversity was significantly greater in exclusion plots relative to inclusion plots, and it was demonstrated that S. Invicta can have an important impact upon cotton arthropods communities, including key predator species.

Effects of malathion ULV applied for boll weevil eradication on survival and foraging activity of the red imported fire ant, Solenopsis invicta Buren, in Texas (USA) cotton

It is suggested that boll weevil eradication with malathion ULV negatively impacts red imported fire ant abundance and foraging and predatory activities in cotton fields.

Dry bolls and their association with Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae) survival through cotton fallow periods

Remaining inside the dry bolls is an important survival strategy for boll weevils during the cotton fallow period, and cotton cultivars with a greater propensity for the formation of dry boll might favour survival of the pest during this period.

The Insecticidal Activities of Fire Ant (Hymenoptera: Formicidae) Venoms Against Plutella xylostella (Lepidoptera: Plutellidae) Larvae

The results of the experiment showed that the larval symptoms induced by fire ant venom include contractile, flaccid paralysis, black coloration and death, and P. xyhstella larvae were most susceptible to S. geminata venom.

Interference between fire ants and mealy bug as well as aphids was recorded in different altitudes of the Eastern Himalayas and found that the incidence of fire ants Solenopsis sp.

It is shown that fallen squares in late-planted cotton contribute more to adult boll weevil populations than bolls, or squares of earlier plantings.

The Conundrum of Chemical Boll Weevil Control in Subtropical Regions

The boll weevil has spread from the tropics to temperate cotton producing areas of the United States and south to northern provinces of Argentina, and chemical intervention against building infestations has been the chief control tactic.

Multiple factors mediate insecticide toxicity to a key predator for cotton insect pest management

Investigating the selectivity of insecticides used against sap-sucking and chewing cotton pests for two E. annulipes populations indicates that insecticide selectivity outcome varies by the insecticide, predator life stage and the predator's behavior.

Failure of the Red Imported Fire Ant to Reduce Entomophagous Insect and Spider Abundance in a Cotton Agroecosystem

Large numbers of the red imported fire ant, Solenopsis invicta Buren, were unable to pauperize the predator arthropod fauna of a cotton field in east Texas, suggesting that it is a fairly specialized predator though probably a polyphagous scavenger.

Red imported fire ants were introduced into an early-planted East Texas cotton plot, while ants were essentially removed from a control plot with Mirex. In the ant plot, predation by ants reduced the

Single‐Factor Analysis in Population Dynamics

A preliminary examination of rather extensive life-table data for the spruce budworm suggested that the factors affecting this species in any one place are of two types-those that cause a relatively constant mortality from year to year and contribute little to population variation, and those thatCause a variable, though perhaps much smaller, mortality and appear to be largely responsible for the observed changes in population.

Differences in Reproductive Potential, Feeding Rate, and Longevity of Boll Weevils Mated in the Fall and in the Fall and Spring

Among groups of weevils which emerged normally, there was no difference in longevity between females remated in the spring and those mated only the previous fall.

Contemporaneous Mortality Factors in Population Dynamics

Abstract The effect of any mortality factor on population trend is influenced greatly by other factors that operate contemporaneously within the same age interval, and by the extent to which it
