| update on the status of africanized honey bees in the western states. | the africanized honey bee (ahb), apis mellifera scutella--perhaps better known as the "killer bee"--has arrived in the western united states and in southern california, following a nearly 50-year north-ward migration across south and central america. first detected near hidalgo, texas in october 1993, the bees continue to advance 100 to 300 miles per year by colonizing existing hives or forming new hives in the wild. although the ahb's "killer" reputation has been greatly exaggerated, the presen ... | 1999 | 10344176 |
| africanization in the united states: replacement of feral european honeybees (apis mellifera l.) by an african hybrid swarm. | the expansion of africanized honeybees from south america to the southwestern united states in <50 years is considered one of the most spectacular biological invasions yet documented. in the american tropics, it has been shown that during their expansion africanized honeybees have low levels of introgressed alleles from resident european populations. in the united states, it has been speculated, but not shown, that africanized honeybees would hybridize extensively with european honeybees. here w ... | 2005 | 15937139 |
| efficacy of strips coated with metarhizium anisopliae for control of varroa destructor (acari: varroidae) in honey bee colonies in texas and florida. | strips coated with conidia of metarhizium anisopliae (metschinkoff; deuteromycetes: hyphomycetes) to control the parasitic mite, varroa destructor (anderson and trueman) in colonies of honey bees, apis mellifera (hymenoptera: apidae) were compared against the miticide, tau-fluvalinate (apistan) in field trials in texas and florida (usa). apistan and the fungal treatments resulted in successful control of mite populations in both locations. at the end of the 42-day period of the experiment in tex ... | 2007 | 17203363 |
| formic acid treatment for control of varroa destructor (mesostigmata: varroidae) and safety to apis mellifera (hymenoptera: apidae) under southern united states conditions. | the efficacy of a formic acid pad formulation was field tested for control of the honey bee parasitic mite varroa destructor anderson & trueman in florida and texas. this pad formulation gave 39.8 +/- 11.1% control at the end of a 6-wk treatment period, which did not significantly differ from the initial sample date. coumaphos treatment provided poor control (38.4 +/- 11.1%) over the 6-wk period, confirming reports of coumaphos resistance in the region. under relatively warm winter conditions in ... | 2004 | 15568336 |
| temporal pattern of africanization in a feral honeybee population from texas inferred from mitochondrial dna. | the invasion of africanized honeybees (apis mellifera l.) in the americas provides a window of opportunity to study the dynamics of secondary contact of subspecies of bees that evolved in allopatry in ecologically distinctive habitats of the old world. we report here the results of an 11-year mitochondrial dna survey of a feral honeybee population from southern united states (texas). the mitochondrial haplotype (mitotype) frequencies changed radically during the 11-year study period. prior to im ... | 2004 | 15212385 |
| the africanized honey bee. | the africanized honey bee (ahb), "the bee with an attitude problem," is described as more defensive, more likely to defend its nest in large numbers, and therefore cause multiple stings compared with the european honey bee (ehb) with which we are familiar. we can expect a greater number of toxic reactions related to multiple stings in addition to the more familiar allergic (ige-mediated) reactions. the title "killer bees" is largely media derived. the first identified colony arriving by natural ... | 2005 | 1577266 |
