Mortality in an invasive ant does not scale linearly with fipronil exposure

Pest Management Science, EarlyView.
Increasing fipronil concentration did not linearly increase yellow crazy ant mortality when introduced via horizontal transfer; high doses may limit food sharing. Queen mortality was low, and surviving workers were averse to feeding. Abstract Background Controlling eusocial invasive and other pestiferous insects is difficult.

The first report of M918L (super‐kdr) and L932F voltage‐gated sodium channel mutations in the English grain aphid (Sitobion avenae)

Pest Management Science, EarlyView.
The study has identified mutations in the voltage gated sodium channel of the English grain aphid (Sitobion avenae) at M918 and L932, which have not been previously reported in this species. Abstract BACKGROUND The grain aphid, Sitobion avenae Fabricius (Hemiptera: Aphididae), is a vector of yellow dwarf viruses and an important pest of cereals.

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

Pest 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

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

Pest 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

Inheritance and fitness costs of field‐evolved resistance to Gpp34/Tpp35Ab1 corn by western corn rootworm, Diabrotica virgifera virgifera (Coleoptera: Chrysomelidae)

Pest Management Science, EarlyView.
Field‐evolved resistance to Gpp34/Tpp35Ab1 corn in two western corn rootworm strains was inherited in a non‐recessive manner and was associated with fitness costs. Abstract BACKGROUND The western corn rootworm, Diabrotica virgifera virgifera LeConte, is among the most serious pests of corn in the United States, and an invasive pest in parts of Europe ...
