Reduced fitness cost accounts for the stability of a malathion‐resistant heterogeneous duplication haplotype in Ceratitis capitata field populations

open access: yesPest Management Science, EarlyView.
Malathion resistance in Spanish field populations of Ceratitis capitata is associated with a point mutation (R allele) and a heterogeneous duplication (RS haplotype) of the Ccace2 gene. The R allele imposes a higher fitness cost than the RS haplotype under laboratory and field conditions. An evolutionary model supports the stability of the RS haplotype

Predation Behavior of the Myrmeleon Brasiliensis (Neuroptera: Myrmeleontidae) Larval Instars

open access: yesRevista Colombiana de Entomología, 2011
Myrmeleon brasiliensis larvae are predators that use the sit-and-wait tactic to catch their prey, and to fulfill this pit-making funnel traps in the sandy soil and remain buried waiting for prey to slip. The objective of this study was to observe the predation behavior of larvae of M ...

Characterization of Cry2Ab2 resistance in Crocidosema sp. (Lepidoptera: Tortricidae): resistance selection, inheritance, cross‐resistance patterns, and fitness costs

open access: yesPest Management Science, EarlyView.
This article reports the first characterization of Cry2Ab2 resistance in Crocidosema sp. Resistance appears to be autosomal and incompletely recessive, with a major‐gene contribution and potential involvement of additional genetic factors, and did not confer cross‐resistance to Cry1Ac or Cry1A.105. Abstract BACKGROUND The soybean bud borer, Crocidosema

Evaluating larvicide performance against Culicoides sonorensis in semi‐field conditions

open access: yesPest Management Science, EarlyView.
This study evaluated the efficacy of larvicide products against Culicoides sonorensis populations under controlled semi‐field conditions. Larvicide efficacy against C. sonorensis declined over time, in different environmental conditions. In particular, precipitation and habitat disturbance influenced residual performance. Abstract BACKGROUND Culicoides

Rapid evolution and genetic basis of spinetoram resistance in Phthorimaea absoluta: evidence from six years of monitoring and laboratory selection

open access: yesPest Management Science, EarlyView.
Resistance to spinetoram in Phthorimaea absoluta is rapidly selected and functionally recessive at field‐relevant concentrations. Metabolic detoxification contributes partially, while cross‐resistance to spinosad and increased susceptibility to diamides and isoxazolines highlight practical options for resistance monitoring and insecticide rotation ...
