In this study, molecular and morphological analysis of Palmicultor Williams, 1963 (Hemiptera: Coccomorpha: Pseudococcidae) mealybugs, intercepted on plant material entering California and collected in Florida, provides evidence for the existence of a cryptic species under the taxon currently known as P. palmarum (Ehrhorn, 1916). A characterization and analysis based on three molecular markers (mitochondrial COI 5′ end and COI 3′ end regions and nuclear rRNA 18S) for all four described species and the putative cryptic species is presented. Morphological characters used to diagnose species of Palmicultor are evaluated, and an updated identification key to adult females is presented. The history of interceptions of invasive species of Palmicultor in California is addressed, and new host plant records are reported. Considering the high intraspecific morphological variability within the genus, the molecular markers sequenced here provide a useful tool to confirm species identity during high-risk interceptions of these mealybugs.","PeriodicalId":56098,"journal":{"name":"Pan-Pacific Entomologist","volume":"97 1","pages":"240 - 260"},"PeriodicalIF":0.5,"publicationDate":"2022-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46815695","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dalmatian toadflax, Linaria dalmatica (L.) Mill., and yellow toadflax, Linaria vulgaris Mill. (Plantaginaceae), are exotic forbs that have become widespread in North America, including California. Both species have accumulated several exotic insects from accidental and intentional introductions. Until recently, Mecinus janthiniformis Toševski & Caldara, 2011 was known to occur at only one location in southern California. Recent surveys of L. dalmatica in northern California recovered M. janthiniformis and a second weevil, Rhinusa neta (Germar, 1821), the latter a new California record. From 2010–2015, M. janthiniformis was recovered at 24 of 27 sites in Lassen, Modoc, Plumas, Siskiyou, and Trinity Counties. After 2014, four locations in Trinity County and one in Sierra County were monitored annually through 2020, but no M. janthiniformis have been recovered to date suggesting this species has not extended its range since 2014. In 2018, R. neta was discovered in L. dalmatica seed capsules in Trinity and Sierra Counties. Later surveys found R. neta infesting L. dalmatica at five locations in four counties and Sairocarpus virga (A. Gray) D. A. Sutton (= Antirrhinum virga A. Gray) (Plantaginaceae), a native species, at one location in Colusa County. The intensity of attack of R. neta on L. dalmatica ranged from 9–70% of seed capsules infested. Being found 300 km south of the Oregon border suggests that R. neta spreads more readily than M. janthiniformis, which has only spread 190 km south of the Oregon border but no further since 2014. Repeated annual sampling at uninfested sites found R. neta to have spread 42 km in one year, an unusually high dispersal rate for exotic Coleoptera.","PeriodicalId":56098,"journal":{"name":"Pan-Pacific Entomologist","volume":"97 1","pages":"150 - 160"},"PeriodicalIF":0.5,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44950978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Peña-Martínez, Néstor Bautista-Martínez;, Rosa María de Guadalupe Quezada-Daniel","doi":"10.3956/2021-97.3.147","DOIUrl":"https://doi.org/10.3956/2021-97.3.147","url":null,"abstract":"Coriander or cilantro, Coriandrum sativum L. (Apiaceae), is a plant used as an ingredient in dishes of Mexican cuisine. In 2017, Mexico exported around 64,000 tons to the United States and Canada, valued at more than US$47 million (SIAP 2019). Today, 6983 ha are cultivated, with Puebla being the largest producer with 3294 ha (SIAP 2021). Since 2018, technicians have reported the presence of an unknown type of aphid on the roots and base of cilantro. In February 2021, aphids were collected in Palmarito Tochapan, Quecholac, Puebla (N18.924975°, W97.644956°). The nymphs and adults were preserved in 70% ethyl alcohol. Using the keys of Blackman & Eastop (2006) and Peña-Martínez et al. (2017), the species was identified as the rice root aphid, Rhopalosiphum rufiabdominale (Sasaki, 1899). The rice root aphid is frequently found on species of Poaceae, Cyperaceae, and Rosaceae (Blackman & Eastop 2006). It has also been reported on cotton (Doncaster 1956), chili and aeroponic pumpkin (Etzel & Petit 1992), tomato and potato (Blackman & Eastop 2000), celery (Dara 2015), and hemp (Cranshaw & Wainwright-Evans 2020). Aldryhim & Khalil (1996) also reported the presence of R. rufiabdominale on C. sativum roots in Saudi Arabia. This report is the first record of the rice root aphid in Mexico affecting the cilantro crop. The collected individuals varied in coloring, ranging from orange in early instars to dark green in wingless adults (Fig. 1). In both cases, a reddish area was visible at the height of the cornicles. This pattern of coloring is distinguishable from Rhopalosiphum maidis (Fitch, 1856), which is bluish green and has dark spots at the base of the cornicles. However, they can be frequently confused with Rhopalosiphum padi (Linnaeus, 1758) because of the reddish coloring at the cornicles, but R. padi has six antennal segments, while R. rufiabdominale has five (Doncaster 1956). Aphid outbreaks can cause significant economic damage. Large populations feeding directly on the crop can cause a reduction in growth, yellowing, and leaf deformation. Some plants infested with rice root aphid exhibited yellowing and reduced growth (Fig. 1a). However, some of the specimens were collected from plants that were not yellowing and were apparently healthy. The highest incidence of this insect in Puebla occurs from December to March, when precipitation is low. The cryptic habit of this aphid makes its detection difficult, and if initial infestations are not detected on time, this can lead to high densities that seriously affect the crop. The purpose of this note is to inform of the presence of R. rufiabdominale on cilantro in Puebla, Mexico, so that growers and field technicians can take timely measures, such as frequent monitoring when there are optimal conditions for development of this pest and management of alternate hosts. In addition, it is necessary to generate information on alternative tools that would allow us to give sound advice for control of this pest.","PeriodicalId":56098,"journal":{"name":"Pan-Pacific Entomologist","volume":"97 1","pages":"147 - 149"},"PeriodicalIF":0.5,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42677479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under this species is a second citation to a new species description of the same name (Pic 1940). After comparing both descriptions, it seems clear that Pic observed two different specimens and species with different characters but assigned both the name P. semiluteus. The 1939 description states the thorax has a black midline and two red spots, while the 1940 description says the thorax is yellow with a red center and three black dots. Pic (1939) also states the size as 9 mm, while it is only 8 mm in the second description (Pic 1940). After comparison of the descriptions, I conclude Pic described two different species. Thus, P. semiluteus Pic, 1940 is a primary homonym requiring a new name (ICZN 1999, Articles 23.3.5 and 60.3). Here, I propose Photinus davisae Keller, nomen novum, to replace P. semiluteus Pic, 1940. Etymology.

Ms. Davis is retiring at the end of August 2021, and this is my way to say thank you. Distribution. Pic (1940) states the type location as “B.-Ayres”, Argentina. Ideally, the holotypes for each species would have been observed, but due to COVID-19 and the recently established policy by the Muséum National d’Histoire Naturelle in Paris not to loan primary types anymore this was not feasible at this time. Pic’s type specimens are also difficult to locate due to the lack of type labels for many species he described.","PeriodicalId":56098,"journal":{"name":"Pan-Pacific Entomologist","volume":"97 1","pages":"179 - 180"},"PeriodicalIF":0.5,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44869164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Arachnids, insects, and centipedes are constantly interacting with each other and with other arthropods (Polis et al. 1981), and field observations of these interactions are important to increasing our knowledge of local food webs. The scorpion genus Centruroides Marx, 1980 currently comprises 93 species and two subspecies (Ponce-Saavedra & Francke, 2019; Rein 2021), 47 of which are found in Mexico (González-Santillán et al. 2019, Ponce-Saavedra & Francke 2019, Quijano-Ravell et al. 2019). Centruroides infamatus C. L.
