 | | Insect control is also beneficial to the transplanted cycad as weakened plants are more susceptible to insect infestations and damage. | | | Cycads used inside the house or in shaded situations should be those that naturally occur in conditions of low light such as most species of Ceratozamia and some species of Cycas and Zamia. | | | Cycads may be successfully transplanted any time of the year, but the best time is just before the start of active growth. |

| | CYCAD |
| | Cycads typically produce a small amount of manoxylic wood, with broad parenchymatous rays and often contain abundant resinous cells and resin canals. | | | Generally, cycads, conifers, seed ferns, Ephedra, Ginkgo, and the angiosperms all have haplochelic stomata, where the guard cells of the stoma develop from one epidermal initial and the associated subsidiary cells from another initial. | | | Cycadophyte leaves (of both cycads and cycadeoids) are widespread from the Triassic to the Upper Cretaceous in Western Europe, Greenland, North America, and a number of southern hemisphere localities. |

| | cycad aulacaspis scale, Aulacaspis yasumatsui Takagi |
| | Although scale insects may be spread short distances by wind dispersal of crawlers, we surmise that the long distance spread of this scale insect is by transport of infested plants. | | | The cycad aulacaspis scale is unusual in that it also infests the roots of its host plant at depths of up to 60 cm in the soil. | | | Cycads continue to appear to be highly infested after most of the scale insects have been killed because the scales do not readily drop off. |

| | PACSOA - Cycad Cultivation |
| | Cycad plantings are well complimented and somewhat easier to manage when underplanted with groundcovers such as ornamental grasses, low-growing flowering perennials, etc. Rocks, pebbles and mulches can all be similarly beneficial in showing a cycad planting to its full advantage. | | | Cycads are horticulturally very forgiving plants, requiring a minimum of attention and being undemanding in their soil, water and other environmental needs; in this respect they are ideal for the low-maintenance garden. | | | The cycad species from the northern parts of Australia are not generally as cold tolerant as those from the more souhern latitudes. |

| | Update on Management Methods for Cycad Aulacaspis Scale |
| | Unfortunately, the cycad aulacaspis scale insect is an unusually hard pest to control. | | | Due to the overall impact of the cycad aulacaspis scale, several researchers are studying the life history and control of this pest. | | | More than 20 species of scale insects occur on cycads in Florida, the most damaging of which is the cycad aulacaspis scale (Aulacaspis yasumatsui Takagi) (Figure 1). |

| | Cycads |
| | Cycads are actually a unique assemblage of plants and although they are grouped with the gymnosperms they are in point of fact unrelated to any other group of living plants. | | | Within the living seed plants they are nearly unique in that they produce motile sperm cells, and thus are an important link to the earliest of the ancient seed plants. | | | The leaves of most cycads are once-divided (pinnate) and often develop an attractive palm-like crown. |

| | Others have suggested that the cycads may be closer relatives of the Medullosales, based on their similarity in growth pattern, mannoxylic wood, the presence of multiple leaf traces per leaf, and a double vascular system in the seeds. | | | The Cycad Pages are an invaluable source of information on cycads, with coverage of every known species. | | | The extinct seed plant group Peltaspermales bears some resemblance to the cycads, and so has been suggested as their sister group. |
