Fig. 3. Coffee berry borer external feeding and reproduction behavior on Cenibroca artificial diet with 60% moisture content at 75% relative humidity. Notice how the external reproduction offers a simple separation of the coffee berry borer immature and adults from the diet for coffee berry borer parasitoid production. (A) Diet pellet 10 to 15 d afer infestation showing external feeding and development of first-generation offspring, arrows showing eggs of first generation. (B) Diet pellet 25 to 30 d afer infestation showing external feeding and development of first-generation offspring. Stages suitable for the African ectoparasitoids (Cephalonomia stephanoderis and Prorops nasuta) reproduction. (C) Diet pellet 35 to 40 d afer infestation showing external feeding and development of first-generation offspring. Notice the presence of mature and teneral females, arrows showing oviposition of second generation. (D) Diet pellet> 50 d afer infestation showing female production, suitable for the reproduction of the African ectoparasitoid P. nasuta.

Fig. 2. Relationships among host tree diameter, height above ground, and site of attack by Euwallacea nr. fornicatus. Density of beetle entrance holes versus the trunk or branch diameter (A) and the trunk or branch height (B) of host Lysiloma latisiliquum from 4 trees. Mean values topped by the same letter are not significantly different (Tukey's test, P = 0.05).

Fig. 1. Mean (+ SE) number of Scyphophorus acupunctatus captured per trap baited with different amounts of fresh agave tissue in 2 trials. The 1st trial was performed from 18 Jan to 8 Feb 2013 (A), while the 2nd trial was carried out from 11 Apr to 23 May 2013 (B). Bars with the same letter are not significantly different (Tukey's, a = 0.05).

Fig. 2. Venn diagram for the relative distribution of proteins spots in control, mechanically wounded, and red palm weevil infested date palm samples. The non-overlapping segment of diagram represent the number of proteins which were significantly up-regulated (> 1.5-fold) in the corresponding group when compared with the other two groups. The overlapping region between any two groups represents the number of protein spots significantly up-regulated (> 1.5-fold) compared to the third one. The central overlapping region depicts the protein spots where no statistically significant change in up- or down-regulation was observed.
