Southern Chinch Bug

Southern chinch bug, Blissus isularis Barber, is the most damaging insect pest of St. Augustinegrass in the United States. St. Augustinegrass is the most common turfgrass used in Florida. The ubiquity of this single turfgrass species makes southern chinch bug an economically important pest in the state. In fact, chinch bugs cost Florida homeowners and professionals millions of dollars every year. This 7-page fact sheet written by Eileen A. Buss, Brianna M. Whitman, and Adam G. Dale and published by the UF/IFAS Department of Entomology and Nematology describes the biology of the pest and the damage it causes and lists ways to scout and monitor for chinch bugs and some strategies for control of the pest.https://edis.ifas.ufl.edu/lh036

Abstract Chalcodermus aeneus Boheman (Coleoptera: Curculionidae) has been the most destructive insect pest of black-eyed peas or cowpeas, Vigna unguiculata L. (Fabales: Fabaceae), over the last century in the southeastern United States. The historical distribution of this semitropical pest suggests the likelihood that diapause plays a key role in the overwintering success in parts of the United States. However, this report is the first to document biological evidence for diapause in C. aeneus. Our study assessed larval emergence from cowpea pods in the summer to fall growing seasons, egg development in female adults over the first (summer) and second (fall) generations, and adult emergence from infested soil after the first and second generations. There was a clear reduction in larval emergence from summer to fall. Egg and follicle development in female C. aeneus dropped off dramatically by September of each year. There was an extended emergence pattern of weevil adults from the soil in the fall as compared to the summer generation. Any future regional management of cowpea curculio will have to take into account the ability of this insect to diapause, thereby increasing its capacity to overwinter in regions where the cowpea crop, a warm-season, semitropical plant, is terminated with winter freezing temperatures.

The rice water weevil, Lissorhoptrus oryzophilus Kuschel, is the most widely distributed and destructive pest of rice in the United States. This 4-page fact sheet written by Matthew T. VanWeelden and Ron Cherry and published by the Department of Entomology and Nematology provides a description of the rice water weevil, its distribution in the state of Florida, methodology for scouting, and options for managing this pest in commercial rice fields.http://edis.ifas.ufl.edu/in1167

Florida accounts for 30% to 40% of all commercially produced fresh-market tomatoes in the United States. Almost every southern county in the state grows tomatoes. This 4-page fact sheet written by Zhengfei Guan, Feng Wu, and Steven Sargent and published by the UF/IFAS Food and Resource Economics Department presents the results of a 2015 study that examined the time it takes to harvest this important crop. http://edis.ifas.ufl.edu/fe1026

The citrus peelminer is a dark-gray moth with mottled white and brown markings and about 4 mm in length. This moth is considered native in the United States, attacking willow. It is believed that a host-shift occurred to multiple non-native plants including all varieties of citrus and certain ornamentals, such as oleander. Citrus peelminer has been reported to occur in low numbers in Florida and at least three Marmara species have been identified in the state. Recent evaluations of an experimental pheromone lure that is still under development by researchers at the University of California, Riverside have confirmed captures of citrus peelminer (Marmara sp.) in Polk County, Florida.

Abstract Tagosodes orizicolus (Muir) is the most important pest of rice in Latin America. Besides causing direct damage called hopperburn from feeding on and ovipositing in rice leaves, this insect pest also transmits rice hoja blanca virus (RHBV, Family Phenuiviridae, Genus Tenuivirus) in a persistent-propagative manner. This pathosystem can cause up to 100% yield loss in Latin American rice fields. T. orizicolus and RHBV symptoms were detected in Louisiana, Mississippi, and Florida rice fields in the 1950s, 1960s, and 1980s. However, neither has been detected in the United States since. Two outbreaks of T. orizicolus on ratoon rice occurred in the fall of 2015 and 2018 in counties southwest and south of Houston, TX. Insects were collected from ratoon rice fields by sweep net methods. Insects from the 2015 and 2018 outbreaks were tested individually and in pools of 10, respectively, for RHBV infection and the cytochrome oxidase 1 (CO1) gene from Delphacidae. No insects were positive for RHBV, however, all samples yielded amplicons for the CO1 gene. Furthermore, the CO1 gene from five 2015 individuals was sequenced and found to have a 100% identity to the Fer26_Argentina and 99.81% identity to the DEL074 Venezuela isolates of T. orizicolus. Five new sequences from 2015 individuals have now been deposited in GenBank. It is imperative to stay up to date on the potential invasion and establishment of this exotic pest of rice in Texas and other rice-growing regions of the United States through continued monitoring and research.

Childcare Policy

For many families across Pennsylvania, child care is an ever-present concern. Since the 1970s, when Richard Nixon vetoed a national childcare program, child care has received little time in the policy spotlight. Instead, funding for child care in the United States now comes from a mixture of federal, state, and local programs that do not help all families. This article explores childcare options available to families in the state of Pennsylvania and highlights gaps in the current system. Specifically, we examine the state of child care available to families in the Commonwealth in terms of quality, accessibility, flexibility, and affordability. We also incorporate survey data from a nonrepresentative sample of registered Pennsylvania voters conducted by the Pennsylvania Center for Women and Politics. As these results support the need for improvements in the current childcare system, we discuss recommendations for the future.

AbstractThe main objective of the study is to trace the perceptions of the task of an aviation component to provide direct aviation support to both ground and naval forces. Part of the study is devoted to tracing the combat experience gained during the assignment by the Bulgarian Air Force in the final combat operations against the Wehrmacht during the Second World War 1944-1945. The state of the conceptions at the present stage regarding the accomplishment of the task in conducting defensive and offensive battles and operations is also considered. Emphasis is also placed on the development of the perceptions of the task in the armies of the United States and Russia.
