Abstract The brown pod-sucking bug, Clavigralla tomentosicollis Stal (Hemiptera: Coreidae), causes significant damage to cultivated cowpea, Vigna unguiculata Walp, a staple crop in sub-Saharan Africa. C. tomentosicollis pierce and suck sap from cowpea pods, resulting in reduced grain yield and quality. The complete, 16,089 bp mitogenome of C. tomentosicollis encodes 13 protein-coding genes (PCGs), 22 transfer RNAs (tRNAs), two ribosomal RNAs (rRNAs) and an A + T rich control region, with gene or...

Adaptation of insect phenotypes for survival after exposure to xenobiotics can result from selection at multiple loci with additive genetic effects. To the authors’ knowledge, no selective sweep analysis has been performed to identify such loci in highly dichlorodiphenyltrichloroethane (DDT) resistant insects. Here we compared a highly DDT resistant phenotype in the Drosophila melanogaster (Drosophila) 91-R strain to the DDT susceptible 91-C strain, both of common origin. Whole genome re-sequenc...

Insecticide-resistant Drosophila melanogaster strains represent a resource for the discovery of the underlying molecular mechanisms of cytochrome P450 constitutive over-expression, even if some of these P450s are not directly involved in the resistance phenotype. For example, in select 4,4’-dichlorodiphenyltrichloroethane (DDT) resistant strains the glucocorticoid receptor-like (GR-like) potential transcription factor binding motifs (TFBMs) have previously been shown to be associated with consti...

In 2010, the initial annotations of the genomes of the body louse (Pediculus humanus humanus Linnaeus) and its primary endosymbiont, “Candidatus Riesia pediculicola,” were completed. The body louse had the smallest genome of any insect sequenced to that point. Prior to the proposal for the sequencing project, there was a dearth of information about louse genes, with no more than around 500–600 inferred open reading frames in public databases. Since the publishing of this genome project, the fiel...

The Drosophila melanogaster 91-R and 91-C strains are of common origin, however, 91-R has been intensely selected for dichlorodiphenyltrichloroethane (DDT) resistance over six decades while 91-C has been maintained as the non-selected control strain. These fly strains represent a unique genetic resource to understand the accumulation and fixation of mutations under laboratory conditions over decades of pesticide selection. Considerable research has been done to investigate the differential expre...

During the 20th century, pesticide use has become integral for current agricultural practices, as has the challenge associated with pesticide resistance. Traditional resistance management plans have often used a “use and discard” approach, changing the chemical to target a different mode of action in the pest species once resistance becomes a problem in the field. An alternative strategy is to identify compounds that confer negative cross-resistance (NCR), where the NCR compound is more toxic to...

We tend to think of the word resistance in terms of evolutionary changes in an insect population that occur in response to repetitive exposures to pesticides or other xenobiotics used to manage insect pests in crops, homes, and gardens, or on livestock or humans (including disease vectors). Resistance can also be defined in broader terms since insects are “resistant” to many naturally occurring abiotic and biotic factors they encounter in their environment. In this chapter, we will outline the c...

BACKGROUND: Moderate to high DDT resistance in generally associated with overexpression of multiple genes and therefore has been considered to be polygenic.
