Part 3 of 8 BOISDUVAL SCALE

All control methods are at their greatest effectiveness against the crawlers, but there is only a fortnight peri­od of effectiveness for each generation. By the time the insects have formed their hardened cover (the scale), it is too late to easily kill those individuals with most pes­ticide formulations. Also, darker colored scales indicate already dead females, but these "shells" are usually full of eggs, which are themselves resistant to controls and will spill when the shell is ruptured or removed.

Light infestations restricted to one or a few plants can usually be treated with household products and considerable hand time rather than concentrated insec­ticides. When possible, immediately isolate infested plants from others to prevent the crawlers from mov­ing amongst them. To bring a serious problem under control you will need to do a treatment every two to three weeks, de-pending on the life cycle in individual growing conditions and control meth-ods used, because the life cycle of scales can be so short, combined with the overlap-ping of generations. Con­sequently, the key factors to scale con­trol are persis-tence, intensity, and regu­lar scheduling of control meth-ods. Because of plant costs, personal at­tachment to plants by owners, and well-meaning desires to avoid insecticides, a variety of home remedies for scale control have been developed over the years by hobby growers. Though such methods may be useful for remov­ing the easy to spot insects, be aware that non-insectici­dal treatments are not likely to be highly effective for com-plete elimination of scales. In order to eradicate Boisduval scale, whether one plant or a greenhouse of plants, the grower may find that only the "big guns" will work. Thus, home remedies should be viewed as con-trols, not necessarily as eradicator methods. Also, many common home chemicals are extremely toxic to hu-mans, pets, and plants even in diluted forms, so due care in judgment of mixing combinations and their use is necessary. Frankly, more often than not, it is more effective and efficient to toss a heavily infected plant.

Biological Control

There are no viable options for biological control of Boisduval scale at this time. Parasitoid wasps from several families do attack this scale. Those of the genus

Ventral aspect of Phaius leaf show- ing a heavy infestation and charac- teristic wilting and curling damage.

ON ORCHIDS PAUL J. JOHNSON

Coccidencyrtus (Hymenoptera: Encyrtidae) particularly are scale killers, and C. ochraceipes is known to kill Boisduval scale in Hawaii and California, and C. malloi in Argenti-na and France. But experimental results in greenhouses are equivocal and these tiny wasps are not generally available commercially. Still, these wasps may be more widely distributed than reported, unrec­ognized, and may be falling victim to sticky traps and insecticides.

The ladybeetles Telsimia nitida and Lindorus lophan-thae (Coleoptera, Coccinellidae) and a Cybocephalus sp. (Coleoptera, Cybocephalidae) are reported to feed on Boisduval scale. I have observed feeding by the conver­gent ladybeetle (Hippodamia convergens) and the other­wise invasive Asian ladybeetle (Harmonia axyridis), but not with significant population reducing effects. Ants (Pheidole sp.) may feed on crawlers occasionally but otherwise seem disinterested in Boisduval scale. None of these are relia-ble for the necessary intensity or dura-

tion to eradicate scale from a greenhouse. Generally speaking, biological controls rarely

elimi­nate the pest species, and this is typically the goal of a grower. Further, biocontrol insects are themselves sus­ceptible to pesticide and other con-trol methods. Sometimes, they can become pests themselves. For example, the Asian ladybeetle will feed on orchid blooms too.

Rubbing Alcohol Probably the most popular and basic home reme-

dy is to swab and daub plants with a cotton-tipped swab
