These data are for individual caterpillars 3rd instar and beyond collected from experimental plants and brought to the lab for rearing. Columns in the file are: Number (collection number, each caterpillar is a separate record, some multiple in one collection number - initially renumbered with decimals, that convention later abandoned); plant number (same as in other file); Collection date; Life History stage (instar); Caterpillar species (s.o. = sleepy orange, Abaeis nicippe; c.s. = cloudless sulfur, Phoebis sennae; o.b.s. = orange-barred sulfur, Phoebis philea); Pupated (yes/no); Pupation date; Adult M/F (No or sex); Parasitized; Virus; Moldy; Discontinued date; comments

Arthropods on Senna mexicana var. chapmannii plants in plantation at TREC, Homestead, Florida 2003-2004

Plants were established, then manipulated throughout the growing season, and weekly observations were made of arthropods. Columns of data are: Plant number; date; block; treatment (1 = TF = tanglefoot; 2 = C = control; 3 = NP = nail polish; 4 = NPC = nail polish control); status (plant alive, sick, dead); sulfurcp (eggs and larvae of Pieridae); flysuck (Ceratopogonidae); tortricid (larvae tying stem tips); spider; bug predators; wasp predators; ladybug (Cocinellidae); fire ants (Solenopsis); Tiny brown ants (Brachymyrmex); Large Black Ants (Camponotus rasilis & C. sexguttatus); Odontomyrmex; crazy ants (Paratrechina); Camponotus abdominalis; weevils; Pseudomyrmex elongatus; Pseudomyrmex mexicanus (=P. gracilis); snakes (occasionally around or in plants). For all ant species, Ceratopogonidae, weevils, only presence/absence on plant was noted (1 = present)

<p>When viruses are involved, the pupae do not hatch, but instead turn various colors.</p

Ants on <i>Senna mexicana</i> var. <i>chapmanii</i> (experimental plantation) plants in Homestead, FL.

<p>Mean and standard error of numbers summed over the field season, over all plants, by treatment. Differences among treatments shown by Kruskal-Wallis for presence/absence data. Treatments abbreviated as C = control, TF = (tanglefoot) ant exclusion, NP = nail polish, NPC = nail polish control. Sample sizes of plants monitored were TF = 12, C = 15, NP = 12, and NPC = 11).</p

Rates of parasitization, virus death, and adulthood reached by caterpillars by treatment.

<p>Sample size is the number of caterpillars collected from plants (3^rd instar and beyond) and reared from plants in each treatment group. Parasitized counts include both definitely and “maybe parasitized” individuals.</p
