Young Southern Field Crop Insect Management Laboratory USDA-ARS, P.O. Box 346 Stoneville, Mississippi 38776 USA Timothy C.

Agric. & Cons . Serv. P.O. Box 1269 Gainesville, Florida 32602 USA ABSTRACT Over a seven-year period, approximately 35,000 spiders representing 26 families, 133 genera, and 234 species were captured in Washington County, Mississippi, by pitfall, sweepnet, vacuum, bag, and hand. Specimens were collected in 10 different habitat types and in four vegetational strata . Old-field habitats yielded the most species (152) and residential lawns the fewest (14) . Considering all habitats sampled, the ground layer produced 111 species, the herbaceous strata 133, the shrub layer 49, and the tree strata 30 species . The sweepnet method of capture obtained 128 species, pitfall 95, hand 61, vacuum 53, and bagging 19 species. The largest number of species were obtained in spring and early summer (maximum of 125 in May), with the fewest in mid-winter (Jan . = 24) . Twenty-one species were considered abundant, 51 common, 67 uncommon, and 95 rare . Additions to the state list of Dorris (1972) number 102 species, for a new state total of 364 species . A comparison with the North American fauna and with other surveys indicates that Washington County is underrepresented both in cursorial forms active on the soil surface and web-spinning forms typical of undisturbed habitats . -

Abstract The expansion of red palm mite (RPM), Raoiella indica (Acari: Tenuipalpidae) in Brazil could impact negatively the native plant species, especially of the family Arecaceae. To determine which species could be at risk, we investigated the development and reproductive potential of R. indica on 19 plant species including 13 native species to the Brazilian Amazon (12 Arecaceae and one Heliconiaceae), and six exotic species, four Arecaceae, a Musaceae and a Zingiberaceae. -

Aphid-Parasitoid (Insecta) Diversity and Trophic Interactions in South Dakota
Proceedings of the South Dakota Academy of Science, Vol. 97 (2018) 83 APHID-PARASITOID (INSECTA) DIVERSITY AND TROPHIC INTERACTIONS IN SOUTH DAKOTA Abigail P. Martens* and Paul J. Johnson Insect Biodiversity Lab South Dakota State University Brookings, SD 57007 *Corresponding author email: [email protected] ABSTRACT Parasitoid wasps of the subfamily Aphidiinae (Hymenoptera: Braconidae) specialize on aphids (Hemiptera: Aphididae) as hosts. The diversity of known and probable aphidiine wasps from South Dakota is itemized, with represen- tation by 13 genera and 42 species, 43% of which are probably adventitious. The wasps and aphids are central to various combinations of multitrophic relationships involving host plants and secondary parasitoids. Selected native and introduced aphid host taxa were quantitatively and qualitatively collected from diverse native and crop host plants in eastern South Dakota and western Iowa. Wasps were reared to confirm plant association, host aphid association, taxonomic diversity, and native or introduced status of the wasps. Acanthocaudus tissoti (Smith) and Aphidius (Aphidius) ohioensis (Smith) were found together on the native aphid Uroleucon (Uroleucon) nigrotuberculatum (Olive), a new host aphid species for both wasps on Solidago canadensis L. (Asterales: Asteraceae). The native waspLysiphlebus testaceipes (Cresson) was repeatedly reared in mas- sive numbers from mummies of invasive Aphis glycines Matsumura on soybean, Glycine max (L.) Merr. This wasp was also reared from the non-nativeAphis nerii Boyer de Fonscolombe and the native Aphis asclepiadis Fitch, both on Asclepias syriaca L. The introduced wasp Binodoxys communis (Gahan) was not recovered from any Aphis glycines population. Hyperparasitoids from the genus Dendrocerus Ratzeburg (Hymenoptera: Megaspilidae), and the pteromalid (Hymenoptera: Pteromalidae) genera Asaphes Walker, and Pachyneuron Walker were reared from mummies of Uroleucon (Uroleucon) nigrotuberculatum parasitized by either Acanthocaudus tissoti or Aphidius (Aphidius) ohioensis. -

Analyses conducted using repetitive DNAs have contributed to better understanding the chromosome structure and evolution of several species of insects. There are few data on the organization, localization, and evolutionary behavior of repetitive DNA in the family Lygaeidae, especially in Brazilian species. To elucidate the physical mapping and evolutionary events that involve these sequences, we cytogenetically analyzed three species of Lygaeidae and found 2n (♂) = 18 (16 + XY) for Oncopeltus femoralis; 2n (♂) = 14 (12 + XY) for Ochrimnus sagax; and 2n (♂) = 12 (10 + XY) for Lygaeus peruvianus. Each species showed different quantities of heterochromatin, which also showed variation in their molecular composition by fluorochrome Genetics and Molecular Research 13 (1): 2186-2199 (2014) ©FUNPEC-RP www.funpecrp.com.br Physical mapping in Lygaeidae 2187 staining.

Insect Egg Size and Shape Evolve with Ecology but Not Developmental Rate Samuel H
ARTICLE https://doi.org/10.1038/s41586-019-1302-4 Insect egg size and shape evolve with ecology but not developmental rate Samuel H. Church1,4*, Seth Donoughe1,3,4, Bruno A. S. de Medeiros1 & Cassandra G. Extavour1,2* Over the course of evolution, organism size has diversified markedly. Changes in size are thought to have occurred because of developmental, morphological and/or ecological pressures. To perform phylogenetic tests of the potential effects of these pressures, here we generated a dataset of more than ten thousand descriptions of insect eggs, and combined these with genetic and life-history datasets. We show that, across eight orders of magnitude of variation in egg volume, the relationship between size and shape itself evolves, such that previously predicted global patterns of scaling do not adequately explain the diversity in egg shapes. We show that egg size is not correlated with developmental rate and that, for many insects, egg size is not correlated with adult body size. Instead, we find that the evolution of parasitoidism and aquatic oviposition help to explain the diversification in the size and shape of insect eggs. Our study suggests that where eggs are laid, rather than universal allometric constants, underlies the evolution of insect egg size and shape. Size is a fundamental factor in many biological processes. The size of an 526 families and every currently described extant hexapod order24 organism may affect interactions both with other organisms and with (Fig. 1a and Supplementary Fig. 1). We combined this dataset with the environment1,2, it scales with features of morphology and physi- backbone hexapod phylogenies25,26 that we enriched to include taxa ology3, and larger animals often have higher fitness4.
