Fig. 1 in Insect visitors to the annual plant community in a xeric environment in Central Mexico

Fig. 1. Abundance-rank curves of the insect species collected visiting the flowers of annual plants in sites with contrasting plant density. Relative abundance is plotted on a log10 scale, and the abscissa is the rank from the most to the least common species (James & Rathbun 1981). Closed triangles and diamonds indicate the abundance of Dasytinae species 1 (Coleoptera) and Miridae species 1 (Hemiptera), in the low and high plant density sites, respectively.

Fig. 1 in Assessment of barrier materials to protect plants from Florida leatherleaf slug (Mollusca: Gastropoda: Veronicellidae)

Fig. 1. Diagram of barrier and soil moisture evaluation arena. Slugs were inoculated onto moist soil in region "a," and could access a leaf disc on moist soil in region "c" afer traversing region "b" that contained wet or dry soil that was either with or without physical 'barrier' material. The circles represent a small plastic Petri dish within a larger Petri dish; the walls of dishes preserved the integrity of the soil moisture treatments.

Fig. 1 in The effects of non-host plant extracts on the oviposition deterrent and ovicidal activity of Conopomorpha sinensis Bradley (Lepidoptera: Gracillariidae)

Fig. 1. The effect of 5 plant extracts on oviposition activity index (OAI) values of Conopomorpha sinensis in the choice test. Plant extracts with oviposition activity indexes of ≥ 0.3 are considered as attractants, whereas those of ≤ −0.3 are considered to be deterrents. Negative values indicate that more eggs were deposited in the control group than those in groups receiving treatment with plant extracts.
