NURSERY/GREENHOUSE INSECT MANAGEMENT

Aphid Management
Over 250 species of the superfamily Aphidoidea feed on agricultural and horticultural crops throughout the world (Blackman & Eastop 1984). Pest aphids tend to have a wider host range than economically unimportant species.

Biocontrol Products
Purchasing and releasing natural enemies for control of insect and mite pests is an attractive alternative to the potential hazards associated with chemical insecticides (i.e., toxic effects on non-target organisms, development of pesticide resistance and persistence in the environment). Furthermore, releasing natural enemies, such as lady beetles, is educational and fun for children and adults alike.

Calculating Dilutions and Site Size
Applying the correct amount of pesticide is a must for responsible, effective pest management. The pesticide label and other recommendations tell you how much to apply.

Consideration for Purchasing and Relasing Biological Control Products
Purchasing and releasing natural enemies for control of insect and mite pests is an attractive alternative to the potential hazards associated with chemical insecticides (i.e., toxic effects on non target organisms, development of pesticide resistance and persistence in the environment). Furthermore, releasing natural enemies, such as lady beetles, is educational and fun for children and adults alike.

Control Options Database
The CONTROL OPTIONS database can be searched by various combinations of parameters. Select the pest from the pull down list. Select only one pest to see the greatest number of controls.

Equipment
The best application equipment for a particular situation is that which provides thorough coverage within a reasonable amount of time and with reasonable effort.

First Japanese Beetle Collected in Texas
Japanese beetles, Papillia japonica Newman (Coleoptera: Scarabidae), are serious pests of turf and ornamental plants in the states east of the Mississippi river except Florida, Mississipi and Minnesota.

Fungus Gnat Management
The term, fungus gnat, applies to a number of species in the insect order Diptera, family Sciaridae (dark winged fungus gnat species Bradysia coprophila, impatiens and paupera). Fungus gnat adults are a nuisance to greenhouse operators, interiorscapers as well as consumers.

Greenhouse Mites
Four groups of mites are important in the greenhouse (Table 1): 1) spider mites (two-spotted spider mites); 2) false spider mites or flat mites; 3)broad and cyclamen mites; and 4) bud, gall, rust or eriophyid mites. Mites are small and are thus difficult to identify.

Home Remedies, Repellents, & 25(b) Products
There are a whole host of "actions" a nursery crop producer can use to try to manage insects in the greenhouse/nursery operation. However, many "novel" methods can be costly and sometimes, ineffective.

Integrated Pest Management Guide
This guide has been prepared to assist producers in developing an IPM program specific to their needs and growing operation. Because the nursery/floral industry is so diverse with little standardization, a great deal of flexibility has been built into this information. However, the basic IPM components are outlined in detail and the format has been designed to fit a wide range of applications.

Managing the Sweet Potato Whitefly
The sweetpotato/silverleaf whitefly has become a widespread difficult-to-control pest of Texas greenhouse and nursery crops since 1987. It is the number one pest of poinsettia grown in Texas nurseries, and control failures have been reported for most conventional insecticides.

Pest Management in Greenhouses
Pest management programs should be designed to meet a specific production objective. In greenhouse production, this objective is usually to produce undamaged pest-free plants. However, in some situations the objective may be to maintain healthy plants.

Pest Management Training Programs Available from TCE
Greenhouse and nursery operators and their employees have a need for access to pest management and pesticide safety training (Note: TCE faculty can use these materials as take-home material for providing Continuing Education Units for individuals maintaining a Texas Department of Agriculture only for private applicators and only if accompanied by a worksheet, e.g., some type of written exercise, for return as proof of completion).

Potting Plugs
Sometimes the simplest of things can be extremely complex. Take potting and transplanting plugs. This is one of the most basic functions in crop production but if plants are not handled properly at this stage, big problems can arise. Mistakes during potting and transplanting are magnified because of the repetitive nature of the entire process.

Sampling and Monitoring for Pests and Their Natural Enemies
Various methods have been devised to sample, or estimate the numbers of, arthropods on trees and shrubs. Many of these procedures were first developed for use in agricultural crops, but several have resulted from investigations on landscape ornamental pests.
