Population genetic structure of the maize weevil, Sitophilus zeamais, in southern Mexico
PLOS ONE, 18(4).
MeSH headings : Animals; Humans; Weevils / genetics; Mexico; Agriculture; Genetic Drift; Genetic Structures; Zea mays / genetics
TL;DR:
It is shown that although there continues to be gene flow between populations of maize weevil, that fine-scale genetic structure exists and is shaped by the movement and trade of maize by humans in the region, by geographic barriers to gene flow, or a combination of factors.

author keywords: Gene drive; CRISPR; slippery slope argument; ethics; regulation
TL;DR:
It is concluded that this argument does not provide compelling reasons for banning the use of gene drives in wild pest populations, but it still has value as a morally instructive cautionary narrative that can motivate scientists, ethicists, and members of the public to think more clearly about appropriate vs. inappropriate uses.

Mathematical modeling of genetic pest management through female-specific lethality: Is one locus better than two?
EVOLUTIONARY APPLICATIONS, 14(6), 1612–1622.
author keywords: eradication; female killing; mathematical modeling; multilocus; population genetics
TL;DR:
A population genetics model with density dependence is used to evaluate the relative effectiveness of female killing approaches based on single- and two-construct arrangements and finds that the single-construct arrangement results in slightly faster population suppression, but the two- construct arrangement can eventually cause stronger suppression and cause local elimination with a smaller release size.

GEOGRAPHIC AND TEMPORAL VARIATION IN MOTH CHEMICAL COMMUNICATION
[Review of ]. EVOLUTION, 63(8), 1987–2003.
Contributors: A. Groot n, O. Inglis n, S. Bowdridge n, R. Santangelo n, C. Blanco *, J. Lopez *, A. Vargas*, n , C. Schal n
author keywords: Experience; female sex pheromone; Heliothis subflexa; Heliothis virescens; male response; phenotypic plasticity; selection
MeSH headings : Animal Communication; Animals; Female; Male; Mexico; Moths / chemistry; Moths / metabolism; Sex Attractants / chemistry; Sex Attractants / metabolism; United States
TL;DR:
The pattern of temporal variation within populations suggests that optimization of the pheromonal signal also may be driven by within-generation physiological adjustments by the moths in response to their experience of the local chemical environment.

JOURNAL OF ECONOMIC ENTOMOLOGY, 100(1), 187–194.
author keywords: DNA diagnostics; resistance monitoring; tobacco budworm; cotton
TL;DR:
The first Bt resistance-causing mutation described at the molecular level was a retrotransposon insertion into the gene encoding a 12-cadherin-domain protein expressed in the midgut of larval Heliothis virescens, and the first large-scale screen for this mutation was reported using a polymerase chain reaction (PCR)-based approach on >7,000 field-collected individuals.

Experimental evidence for interspecific directional selection on moth pheromone communication
PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA, 103(15), 5858–5863.

MeSH headings : Animals; Female; Genotype; Male; Moths / genetics; Moths / physiology; Phenotype; Pheromones / physiology; Regression Analysis; Sexual Behavior, Animal
TL;DR:
It is quantitatively estimate that the directional selection exerted by Hv males on Hs females to produce relatively high amounts of acetates can range from 0.135 to 0.231, which may counteract intraspecific stabilizing selection that impedes evolutionary changes in pheromone blends and could lead to diversification of sexual signals.

The HevCaLP protein mediates binding specificity of the Cry1A class of Bacillus thuringiensis toxins in Heliothis virescens
BIOCHEMISTRY, 43(44), 14299–14305.
MeSH headings : Animals; Bacillus thuringiensis / genetics; Bacillus thuringiensis / metabolism; Bacillus thuringiensis Toxins; Bacterial Proteins / metabolism; Bacterial Toxins / metabolism; Binding, Competitive; Cadherins / genetics; Cadherins / physiology; Endotoxins / metabolism; Genotype; Hemolysin Proteins; Insect Proteins / genetics; Insect Proteins / metabolism; Insect Proteins / physiology; Iodine Radioisotopes / metabolism; Microvilli / metabolism; Moths / microbiology; Phenotype; Protein Binding; Receptors, Cell Surface / metabolism; Transport Vesicles / metabolism
TL;DR:
Testing the correlation between BtR-4 gene disruption, lack of HevCaLP, and altered Cry1A toxin binding supports the earlier suggestion that a separate genetic change occurred in YHD2 after appearance of the cadherin disruption, conferring even higher resistance in the resulting Y HD2-B strain as well as a large reduction in Cry1Ab and Cry1Ac binding.

Do dynamics of crop maturation and herbivorous insect life cycle influence the risk of adaptation to toxins in transgenic host plants?
Onstad, D. W., & Gould, F. (1998, June). ENVIRONMENTAL ENTOMOLOGY, Vol. 27, pp. 517–522.
author keywords: Ostrinia nubilalis; Zea mays; Bacillus thuringiensis; insecticide resistance; host plant resistance
TL;DR:
It is hypothesized that genetically engineered toxins will often decrease in leaf and stem titer as crops reach maturation, and the insects feeding and surviving on a crop during its senescence may have important consequences for the population genetics of the breakdown of host plant resistance.

author keywords: Nomuraea rileyi; Bacillus thuringiensis toxin; tritrophic interactions; host plant resistance
TL;DR:
It is hypothesized that a pathogen should interact with herbivore behavior to accelerate Herbivore adaptation to toxic plants: individuals not adapted to toxin tend to move more on toxic plants, and therefore are more likely to encounter a lethal dose of pathogen, further increasing the probability that they will be eliminated by selection.
