| 0019013 | red grass thrips | Aptinothrips rufus | small wingless , yellow color , antenna 6 segments with large terminal segment and simple sense cones, pronotal setae not long, 1-segmented tarsi Note anterior antenna and pronotum. Found on Star Moss and Bromus inermis, Festuca arundinace.

| 0019014 | grass thrips | Anaphothrips obscurus | Second-instar larvae are yellow with grey markings, medially on the head, two spots laterally on the pronotum, and transversely on tergites IX and X near the posterior margin. Tergite IX bears two pairs of setae with the apices capitate, and the posterior margin of this segment has a row of teeth. Body yellow with brown markings, antenna 9 segments with VI having at least a partial transverse suture Males of A. obscurus are not known; worldwide the species has never been confirmed to be other than parthenogenetic. The females are dimorphic, either fully-winged (macropterous), or short-winged (micropterous or brachypterous). The macropterae are mainly yellow in colour, although the posterior margin of the head has a brown transverse marking, and the anterior tergites are variably shaded with brown; the forewings are slightly yellow, and the distal antennal segments are mainly brown. Micropterous individuals are usually almost clear yellow. The head and pronotum have no long setae, in contrast to most other pest thrips species. The abdominal tergites are completely sculptured medially, and the eighth abdominal tergite has a complete comb along the posterior margin. Found on corn, rice, wheat, and grasses (per CPC). Host and distribution information from Crop Protection Compendium (CPC) and SFO collection Europe, Asia, Africa, Oceania, pacific, Western Hemisphere CPC Damage: Kamm (1971) recorded a 16% reduction in seed yield of bentgrass (Agrostis stolonifera) in Oregon, USA, and added that subsequent damage to the leaves of the plants almost certainly resulted in further yield reduction. In other reports of yield reduction in grasses grown for seed it is clear that A. obscurus is only one of a group of thrips species that are associated with such damage (Zawirska, 1970). Near Beijing in China, Han et al. (1979) noted that A. obscurus caused serious damage to young maize in late spring if large populations had first built up on wheat in spring and then migrated to maize. Rains depressed population size, but drought increased them. |

| 0019004 | coconut palm | Cocos nucifera | |
| 0019005 | byfield fern | Bowenia serrulata | "As its common name suggests, this cycad has far more in common, appearance wise, with ferns than with cycads. Rather than the typical circular layout of leaves, these leaves stand up straight, up to 1.5 metres (5 feet) high, and are branched, having between 6 and 10 branches on a mature leaf. The individual leaflets, arranged bipinnately around the stem, are usually between 60 to 100 mm (2.5 - 4 ins) long, 20 - 30 mm ( 0.75 - 1.25 ins) wide and are a dark, shiny green, with serrated edges. They have the standard pineapple shaped cone, producing green/purple, oval seeds, 30 mm (2.25 in) long. " Citation from the Palm & Cycad Societies of Australia at http://www.pacsoa.org.au/cycads/Bowenia/serrulata.html "Because of their attractiveness, the leaves of this plant were regularly harvested for use in floral arrangements. Collectors used to be able to get a licence for the exclusive rights to harvest in a certain area. The plants are now protected [added-CITES Appendix II], and they are far too slow growing to be produced commercially for this use, so they are now rarely seen in floral arrangements. occasionally one sees plastic copies of the leaves, however."

| 0019001 | mango scale | Aulacaspis tubercularis | The female armor (cover) is white with a circular, flat, thin and often wrinkled shaped. Exuviae is submarginal giving the appearance of median black ridge or bar (especially at low power). Male covers are small, white, sides nearly parallel and with three distinct carinae. The adult female is characteristically shaped with an elongate and somewhat parallel-sided pygidium. This is one of the few pests found on mangoes that can be identified in the field for the most part because of the "bar" characteristic. The cover MUST have the black bar-shaped submarginal character.
