Dispersal of the egg parasitoid Gryon gallardoi (Brethes) (Hymenoptera: Scelionidae) in tobacco crops.
A mass marking-recapture experiment was carried out to study the dispersal of Gryon gallardoi (Brethes) (Hymenoptera: Scelionidae) in tobacco crops. Parasitoids emerged in the laboratory were marked with dye powder. Six separate field trials were conducted in Jan/Feb 2002 involving the simultaneous release of marked parasitoids. Dispersal was determined by the recapture of individuals in sets o...
متن کاملMorphology and distribution of antennal sensilla of Gryon gallardoi (Brèthes) (Hymenoptera: Scelionidae) females.
With the aid of scanning electron microscopy, the external morphology and distribution of the antennal sensilla were described for females of Gryon gallardoi (Bréthes), an egg-parasitoid of coreids. The geniculated and clavated antennae are composed of 12 antennomeres. Along the flagelum we registered dorsal glands and seven types of sensilla: papillary, chaetica of two sizes--long and short ty...
متن کاملReproductive parameters and longevity of Gryon gallardoi (Brethes) (Hymenoptera: Scelionidae) parasitizing Spartocera dentiventris (Berg) (Hemiptera: Coreidae) eggs.
The fecundity, daily progeny and longevity of Gryon gallardoi (Brethes) (Hym.; Scelionidae) were determined under laboratory conditions, using Spartocera dentiventris (Berg) (Hem.; Coreidae) eggs as host. Nineteen G. gallardoi females and 34 males were reared at 25 +/- 1 degrees C, with a 12 h photophase, fed on a 10% aqueous honey solution and provided with 25-30 S. dentiventris eggs daily. Th...
متن کاملEffects of egg age of Spartocera dentiventris (Berg) (Hemiptera: Coreidae) on parasitism by Gryon gallardoi (Brethes) (Hymenoptera: Scelionidae).
To evaluate the effect of egg age of Spartocera dentiventris (Berg) on the parasitism by Gryon gallardoi (Brethes), groups of 12 eggs of 2, 3, 4, 5, 6, 7, 8, and 12 days old were exposed to one female of G. gallardoi on a test tube, with the wasp observed for 2h subsequently. Later, the eggs were individualised and incubated (25 +/- 1 degrees C; 12h photoperiod) until adult emergence. To identi...
متن کاملOn the misidentification of Anagrus ustulatus Haliday (Hymenoptera: Mymaridae).
The cosmopolitan genus Anagrus Haliday is one of the largest in Mymaridae (Hymenoptera: Chalcidoidea), and includes very common egg parasitoids, mostly of leafhoppers. The smallest species (body length: 0.4-0.6 mm) are found in the atomus species group. This group at present includes about 20 species worldwide. Anagrus atomus (Linnaeus) is among the most common species in the Palaearctic region...
