Effect of bacterial strains isolated from the medfly on the average length of larvae developing in fruit. Surface sterilized eggs incubated in a pure culture of each isolate or in an equal mixture of all isolates (Mix), all in PBS, were subsequently inoculated into plums. Larval length was recorded after eight days. Control eggs were treated with sterile PBS Treatments differing significantly from the control are denoted by asterisks (Wilcoxon signed rank test, Z = − 4.23, P < 0.0055)
