Orchid Insect and Mite Pests in South Florida

Doug Caldwell and Twyla Leigh

This publication presents information on the most common and damaging arthropod pests of orchids. It is based on literature review and interviews with local nurseries in the Ft. Myers and Naples, Florida, area as well as with local orchid club members. Orchids are one of the most popular plants in the ornamental realm. Extension agents and Master Gardeners need information to help address client questions about orchid ailments and orchid pests.

Presence of a Non-Pest Mite Tarsonemus confusus Ewing (Acari: Tarsonemidae), in Florida Strawberry Fields

Lovely Adhikary and Sriyanka Lahiri

This publication aims to benefit growers and Extension agents by increasing awareness of a fungus-feeding mite, Tarsonemus confusus, commonly found in strawberry fields. Tarsonemus confusus may be misidentified as other pest mites. In fact, without help from an expert mite taxonomist, incorrect species identification can be a major concern. Although this mite species typically does not achieve pest status on most crops, an incorrect pest identification may lead to unnecessary application of miticides, triggering a secondary pest outbreak.

Using Wolbachia Bacteria to Control Mosquitoes and Mosquito-Borne Disease

Leena A. Salama, Abdullah A. Alomar, Daniel W. Pérez-Ramos, and Eric P. Caragata

This publication is intended for both the general public and mosquito control professionals. It outlines the use of the bacterium Wolbachia pipientis as a tool to control mosquito populations and reduce the spread of mosquito-borne disease. Biting mosquitoes transmit many pathogens that cause deadly diseases in people, our pets, and our livestock. Collectively, malaria, dengue, West Nile, filariasis, and other mosquito-borne diseases result in millions of infections and hundreds of thousands of deaths every year. Effective vaccines for most of these have not been developed or are not yet available to the general public, and disease management is focused on controlling mosquito populations. Insecticides have become less effective over the past fifty years as mosquito populations all over the world have developed resistance. This has driven scientists to explore new options for controlling mosquitoes, including using the bacterium Wolbachia pipientis.

Monitoring for Amoebic Disease (Malpighamoeba mellificae) in Honey Bee Colonies

Hannah N. Gurland, James C. Fulton, Marley E. Iredale, Amy Vu, and Julia St. Amant

Digestive health is an overlooked but vital component of the success of Western honey bee (Apis mellifera) colonies. Viral, bacterial, fungal, and protozoal infections can inhibit nutrient uptake and waste elimination by the honey bee digestive tract. Active management requires monitoring honey bee health on an individual and colony basis, providing adequate nutrition, and controlling for other pests and diseases. One organism that has gained recent attention is Malpighamoeba mellificae. This publication describes how to detect M. mellificae in A. mellifera colonies.

A Guide to Selecting and Using Pesticides During the Blueberry Pollination Period: How Can We Reduce Risk to Pollinators?

Rachel E. Mallinger, John J. Ternest, and Douglas A. Phillips

This publication provides blueberry growers strategies for choosing and applying fungicides and insecticides during bloom so as to minimize harm to pollinators. Insect pollinators, particularly wild and managed bees, are necessary to achieve adequate fruit set in blueberries. Without insect pollinators, berries may form, but they will be significantly smaller and misshapen and will take longer to ripen than bee-pollinated berries. Managed bees, wild bees, and other insect pollinators are susceptible to pesticides, especially when applied during bloom when pollinators are foraging in blueberry fields. Growers thus must balance disease and pest protection with pollinator protection. This publication provides information on the toxicity to pollinators and residual activity of insecticides and fungicides used during blueberry bloom, and strategies for minimizing pollinator exposure.

A Concise Guide on the Bionomics and Key Morphological Characteristics for Identifying Aedes pertinax (Grabham, 1906) – a Mosquito Species from the Neotropics Expanding in Geographic Range

Ana L. Romero-Weaver, Michael T. Riles, Kristin Sloyer, Yoosook Lee, Lindsay P. Campbell, and Bryan V. Giordano

Aedes pertinax is a non-invasive mosquito first described in Jamaica by Grabham in 1906. It is currently classified in the Protoculex Group. It was first identified in the U.S. in 2015; its current distribution is unknown because it is so difficult to differentiate it from other mosquito species that are morphologically similar. It has not been reported in association with humans or animal diseases, but Ae. Atlanticus, another mosquito in the Protoculex Group, is a vector of the Keystone virus and the West Nile virus, which have the potential to cause encephalitis and death. Moreover, Ae. serratus, once classified as synonym of Ae. pertinax, was reported infected with yellow fever in Brazil in 2008. Because Ae. pertinax may be a vector and because it has expanded its geographical range, it should be monitored closely. This publication provides a description of the species so that it can be identified and monitored.

Arthropod Pest Management Practices of Strawberry Growers in Florida: A Survey of the 2019–2020 Field Season

Sriyanka Lahiri

This publication is aimed at growers, Extension agents, industry partners, and the general public who have an interest in integrated pest management (IPM) tools used by growers in general and strawberry growers in particular. The purpose is to establish a baseline of adopted IPM practices by the strawberry industry in Florida so that changes in behavior can be tracked in future. To document the current pest management practices, an in-person survey of 24 strawberry growers in Hillsborough Co., FL was conducted (IRB# 201902072) during the field season of 2019-2020. The survey showed that 70% of strawberry growers spray their crop more than 5 times in a season with an insecticide/miticide. But strawberry growers have developed an awareness of IPM tools available to them and are already using these tools such as releasing biological control agents for mite management, cover cropping, and considering planting banker (flowering) crops in designated spaces in and around their fields.

Chagas Disease: A Review of Vector-Borne Transmission by Triatomine Bugs (Hemiptera, Reduviidae, Triatominae)

Bethany R. Eutsey, Cameron J. Jack, Shelley A. Whitehead, and Eva A. Buckner

Chagas disease is a potentially fatal, chronic disease caused by Trypanosoma cruzi, a protozoan parasite. It causes 6 to 8 million cases and 50,000 deaths each year. Humans and animals usually become infected with T. cruzi via triatomine bugs, also called kissing or conenose bugs, found only in the Americas. Disease transmitted by triatomine bugs generally occurs in rural areas of Mexico, Central America, and South America, but it is becoming more prevalent in non-endemic areas like the US as asymptomatic infected people move from rural to urban areas of Latin America and other regions. In the US, approximately 300,000 people are currently infected with Chagas disease, 18,000 in Florida. Most if not all of them were infected elsewhere; local transmission of Chagas disease via triatomines in the US is rare. Awareness and understanding of Chagas disease are critical to detect and treat cases early. This publication is intended for anyone interested in learning more about Chagas disease.

Common Arthropod Pests in Blackberries and Pomegranates in Florida

Chastity Perry, Hugh Smith, Zhanao Deng, and Sriyanka Lahiri

Blackberry and pomegranate are growing in importance as alternative crops in Florida. In the past decade, blackberry production in Florida increased from 64 acres in 2007 to 173 acres in 2017. The many health benefits acquired from these fruits make them good alternative options for growers in Florida to diversify their operations by planting some new and less traditional crops, providing them a niche in the Florida agriculture market. The intended audience of this publication includes blackberry and pomegranate growers in Florida as well as Extension agents providing expert recommendations to both these industries. The purpose of this publication is to share information derived from a one-year field survey on commonly encountered pests.

Container Mosquito Habitat Community Cleanup: A How-To Guide for Event Organization

Amy Hallock, Eva A. Buckner, Ricky W. Telg, and Alena R. Poulin

Being bitten by the container mosquitoes Aedes aegypti and Ae. albopictus means a higher risk of becoming infected with Zika, dengue, or chikungunya virus. Container mosquitoes develop in the water that collects in discarded tires, jars, cans, buckets, and boats. The best way to prevent irritating bites and dangerous mosquito-transmitted illnesses is to get rid of all trash that holds water. This fact sheet is packed with recommendations that will help you to successfully develop and host a cleanup event to reduce potential mosquito larval habitats in your community and keep yourself and your neighbors safe.

Cover Crops for Managing Root-Knot Nematodes

Harsimran K. Gill, Zane J. Grabau, and Robert McSorley

Cover crops are grown between cash crop cycles or incorporated with cash crops to improve soil fertility and structure, decrease soil erosion, and suppress weeds, insects, nematodes, and other plant pathogens. Cover crop residues can be incorporated as “green manure” to increase soil fertility for the next crop. Cover crops also help to enhance many beneficial organisms and may contribute to carbon sequestration. They help curtail the spread of nematodes because nematodes cannot migrate to another field if a cover crop is not a host to them. Instead, some of them may starve, which helps to manage their population. Fallow soil also helps keep nematode populations lower, but it may lead to erosion and other problems. Many different types of cover crops are adapted for cultivation in the southern United States, including cowpea, sorghum-sudangrass, sunn hemp, marigolds, jointvetch, sesame, grasses, rye, wheat, oats, crimson clover, vetch, lupine, and, of late, legumes.
