TAP Sampling for Asian Citrus Psyllid (ACP) Field Sheet

Jawwad A. Qureshi and Phil Stansly

Monitoring ACP populations is an important tool in the integrated management of citrus greening. The most efficient way to estimate field populations of this insect is by monitoring adults. Tap sampling has proven to provide data needed to make informed decisions for managing this insect pest. Other pest and beneficial insects and mites may fall on the sheet and can also be counted. We recommend 10 tap samples in each of the 10 locations per block, 5 on the periphery and 5 in the interior. ACP tends to accumulate on the block periphery, which therefore may require more frequent sprays.

Muestreo por Golpeo para el Psílido Asiático de los Cítricos (PAC). Hoja de campo

Jawwad A. Qureshi and Phil Stansly

El monitoreo de las poblaciones del PAC es muy importante en el manejo integrado de la enfermedad llamada enverdecimiento de los cítricos. La manera más efectiva de estimar las poblaciones de este insecto en campo es el muestreo de adultos. El muestreo por golpe ha probado ser una herramienta que provee los datos e información necesarios para la toma de decisiones en el manejo de esta plaga. Otras plagas, insectos y ácaros benéficos podrían caer también a esta hoja y ser contados. Se recomiendan 10 muestreos en cada una de 10 localizaciones por bloque, 5 en la periferia y 5 en el interior. El PAC tiende a acumularse en la periferia del bloque, que por lo tanto puede requerir aplicaciones para su control más frecuentes.

Citrus Rust Mite Phyllocoptruta oleivora (Ashmead) (Arachnida: Acari: Eriophyidae)

Leptomastix dactylopii Howard (Hymenoptera: Encyrtidae): parasitoid of mealybugs (Hemiptera: Pseudococcidae)

Salman Al-Shami and Jawwad A. Qureshi

This publication describes the biology, distribution, behavior, and impact of the parasitoid Leptomastix dactylopii Howard. This beneficial insect is known for providing significant reductions in mealybug populations in Florida and other locations. It is also intended to provide knowledge about this parasitoid to a wide range of interested audiences including growers, Extension agents, researchers, students, laypersons, and other stakeholders.

Individual Protective Covers (IPCs) for Young Tree Protection from the HLB Vector, the Asian Citrus Psyllid

Fernando Alferez, Ute Albrecht, Susmita Gaire, Ozgur Batuman, Jawwad Qureshi, and Mongi Zekri

Psyllid exclusion is the most effective strategy to keep citrus trees free from HLB. Individual protective covers (IPCs) are a novel strategy based on psyllid exclusion of individual trees using a protective mesh bag. This new 3-page publication summarizes the knowledge we have accrued from our 3-year-long field studies using the IPC system and provides recommendations that can help with effective use of this technology. By F. Alferez, U. Albrecht, S. Gaire, O. Batuman, J. Qureshi, and M. Zekri.

Insect Management for Legumes (Beans, Peas)

Jawwad A. Qureshi, Dakshina Seal, and Susan E. Webb

Many different insects attack leguminous vegetables. Aphids damage terminals, whiteflies feed on sap and transmit bean golden mosaic virus, and caterpillars, like bean leafroller, and beetles feed on leaves. Flower thrips feed in blossoms and stink bugs, corn earworm, and leaffooted bugs damage seeds and pods.

Insect Management for Cucurbits (Cucumber, Squash, Cantaloupe, and Watermelon)

Jawwad A. Qureshi, Dakshina Seal, and Susan E. Webb

Insects and mites can cause severe problems in the production of watermelon, squash, cucumber, and cantaloupe either through direct feeding damage to the crop or through the transmission of disease agents, such as the aphid-borne mosaic viruses. Common pests of cucurbits are described below. For each pest described, a table of management options will be found after the damage. Pesticides for controlling insects not described below can be found by looking under the "Insects" column in the table.

The Citrus Red Mite (Panonychus citri): A Pest of Citrus Crops

Emilie Demard and Jawwad A. Qureshi

Panonychus citri is a phytophagous mite of economic importance in open citrus orchards and a major pest in Citrus Under Protective Screen (CUPS), a new undercover production system tested in Florida. Immatures and adults feed on citrus leaves, fruits, and green twigs resulting in mesophyll collapse, shoot dieback, and fruit drop. In Florida, P. citri occurs throughout the year but is most abundant in spring or early summer and autumn or early winter. Although chemical sprays like Abamectin or Fenbutatin oxide provide some control of P. citri, resistance has been reported in different regions of the world. Several predatory insects and mites have been shown to attack the mite and could be potential natural enemies to use in biological control programs.

Insect Management for Okra

Jawwad A. Qureshi, Dakshina Seal, and Susan. E Webb

Okra is a warm-weather crop grown in the summer throughout Florida. Most commercial production is concentrated in South Florida, where it can be grown most of the year. It is often grown as a second crop after more valuable vegetables.
