The cultivation of sweet herb of great economic importance for small farmers in the micro and Agrest Swamp of Paraíba and also in the state of Pernambuco. Among the natural enemies, the scissors Euborellia annulipes proves to be a voracious predator, that is, with high ability to attack and feed on different prey, particularly of eggs and immature stages of insects of Lepidoptera, Hemiptera, Coleoptera and Diptera. The objective of this research was to study the biological aspects of E. annulipes on H. foeniculi laboratory. The study was conducted at the Entomology Laboratory, Department of Plant Protection at the UFPB in a climatic chamber, at 25 ± 1 ºC, relative humidity of 70 ± 10% RH and 12 hours. Scissors were selected in adulthood from rearing on artificial diet in the laboratory. From these insects have made observations of posture, viability and morphology of eggs of E. annulipes. Fifty nymphs were selected for each stage of development (1, 2, 3, 4 and 5) of the scissors and fed separately with aphids (1st-2nd, 3rd and 4th instar). There has been evaluation regarding the number and duration of instars. There are five instars to the nymphal stage of E. annulipes, the average incubation period was 12.9 days, pre-oviposition period of 18.2 days and 46.75 eggs per clutch, there was an increase of nymphal E. annulipes in that it offered up more aphids developed.
