In April 2018, specimens of an asterolecaniid were collected on infested wild plants of Asclepias curas­savica Linnaeus, 1753 (Gentianales: Asclepiadaceae) in Jiquilpan, Michoacan, Mexico. The collected specimens were identified as Planchonia stentae (Brain, 1920) (Hemiptera: Asterolecaniidae). In this paper, we record for the first time the presence of P. stentae infesting A. curassavica in Mexico

Revision of the family Asterolecaniidae (Hemiptera: Coccomorpha) in Argentina

The Asterolecaniidae (Hemiptera: Coccomorpha), known as pit scales, are currently represented by 11 genera and 52 species in the Neotropical region, and by five species in Argentina. The goal of this study is to review and update the information currently known about the biodiversity of Asterolecaniidae in Argentina. We describe Argenta Granara de Willink new genus, Argenta eduardoi Granara de Willink new species, Mycetococcus ligae Granara de Willink new species, and Sclerosococcus williamsi Granara de Willink new species; an illustration of Pollinia pollini (Costa) is also included; the species Asterolecanium puteanum Russell and Russellaspis pustulans (Cockerell) are noted for the first time in Argentina. Dichotomous keys to the genera of Asterolecaniidae and the species of Asterolecanium Targioni-Tozzetti, Mycetococcus Ferris, and Sclerosococcus McKenzie in Argentina are presented. This work increases the number of known species in Argentina to ten.

Triangle network motifs predict complexes by complementing high-error interactomes with structural information

BackgroundA lot of high-throughput studies produce protein-protein interaction networks (PPINs) with many errors and missing information. Even for genome-wide approaches, there is often a low overlap between PPINs produced by different studies. Second-level neighbors separated by two protein-protein interactions (PPIs) were previously used for predicting protein function and finding complexes in high-error PPINs. We retrieve second level neighbors in PPINs, and complement these with structural domain-domain interactions (SDDIs) representing binding evidence on proteins, forming PPI-SDDI-PPI triangles.ResultsWe find low overlap between PPINs, SDDIs and known complexes, all well below 10%. We evaluate the overlap of PPI-SDDI-PPI triangles with known complexes from Munich Information center for Protein Sequences (MIPS). PPI-SDDI-PPI triangles have ~20 times higher overlap with MIPS complexes than using second-level neighbors in PPINs without SDDIs. The biological interpretation for triangles is that a SDDI causes two proteins to be observed with common interaction partners in high-throughput experiments. The relatively few SDDIs overlapping with PPINs are part of highly connected SDDI components, and are more likely to be detected in experimental studies. We demonstrate the utility of PPI-SDDI-PPI triangles by reconstructing myosin-actin processes in the nucleus, cytoplasm, and cytoskeleton, which were not obvious in the original PPIN. Using other complementary datatypes in place of SDDIs to form triangles, such as PubMed co-occurrences or threading information, results in a similar ability to find protein complexes.ConclusionGiven high-error PPINs with missing information, triangles of mixed datatypes are a promising direction for finding protein complexes. Integrating PPINs with SDDIs improves finding complexes. Structural SDDIs partially explain the high functional similarity of second-level neighbors in PPINs. We estimate that relatively little structural information would be sufficient for finding complexes involving most of the proteins and interactions in a typical PPIN

First record of \u3ci\u3eDactylopius confusus\u3c/i\u3e (Cockerell, 1929) (Hemiptera: Coccomorpha: Dactylopiidae) in Michoacan, Mexico

In April 2017, several scale insect specimens in the family Dactylopiidae were collected from infested cladodes of wild Opuntia tomentosa Salm-Dyck, 1822 (Cactaceae) in the outskirts of Morelia City, Michoacan, Mexico. The specimens were identified as Dactylopius confusus (Cockerell, 1929) (Hemiptera: Coccomorpha: Dac­tylopiidae). In this article, the presence of D. confusus in Michoacan state, Mexico, is recorded for the first time. A subsequent finding of D. confusus on Opuntia ficus-indica (L.) Mill., (1768) (Cactaceae) in October 2019 was confirmed with 18S rDNA and 28S rDNA
