Oocyte membrane localization of vitellogenin receptor coincides with queen flying age, and receptor silencing by RNAi disrupts egg formation in fire ant virgin queens
TLDR
Silencing of the receptor in virgin queens through RNA interference abolished egg formation, demonstrating that VgR is involved in fire ant ovary development pre mating. Expand
Host regulation and release of parasitism-specific proteins in the system Toxoneuron nigriceps-Heliothis virescens.
TLDR
The braconid wasp Toxoneuron nigriceps induced qualitative and quantitative changes in the protein composition of the moth Heliothis virescens host hemolymph, and incubation of host derived tissues, parasitoid larvae and teratocytes in 35S conditioned media suggested PSPs were a product of teratocyte. Expand
Changes in differential haemocyte count and in vitro behaviour of plasmatocytes from host Heliothis virescens caused by Campoletis sonorensis polydnavirus
TLDR
The abnormalities induced in H. virescens plasmatocytes by C. sonorensis virus contribute to the suppression of encapsulation, and the onset of haemocytic abnormalities occurred more rapidly after natural parasitism of 3rd-instar host larvae. Expand
Quantitative food distribution studies within Laboratory colonies of the imported fire ant,Solenopsis invicta Buren
TLDR
The distribution of three forms of egg yolk protein, liquid bovine hemoglobin, soybean oil, honey, and water was studied in laboratory colonies of the imported fire antSolenopsis invicta Buren to determine the distribution of food and average cumulative consumption in micrograms or microliters. Expand
Passive evasion by eggs of braconid parasitoid Cardiochiles nigriceps of encapsulation in vitro by haemocytes of host Heliothis virescens. Possible role for fibrous layer in immunity
TLDR
It is proposed that the fibrous layer may, among other possible functions, delay encapsulation until a more permanent means of suppressing encapsulation of the egg is established in the host. Expand
A possible mechanism for the physiological suppression of conspecific eggs and larvae following superparasitism by solitary endoparasitoids.
TLDR
It is suggested that the general changes in the hemolymph of a parasitized host become unfavorable for the development of newly oviposited eggs. Expand
Encapsulation reactions in vitro by haemocytes of Heliothis virescens
TLDR
Preliminary evidence indicates that encapsulation promoting factors in the lysate originate in haemocytes, which is similar to those formed in vivo. Expand
Differential gene expression during wing morph differentiation of the ectoparasitoid Melittobia digitata (Hym., Eulophidae).
TLDR
The differential gene expression between SWM and LWM larvae of M. digitata is described in order to unravel the molecular mechanisms controlling the morph differentiation in this minute parasitoid and pinpoint the pathways involved in the regulation of this developmental process. Expand
Induction of a new haemolymph glycoprotein in larvae of permissive hosts parasitized by Campoletis sonorensis
TLDR
Parasitization by Campoletis sonorensis consistently results in the appearance of a new polypeptide, a glycoprotein, in several habitual host species, and can be duplicated by the injection of either calyx fluid or purified C. sonoresis virus. Expand
Effect of parasitism by Cardiochiles nigriceps on food consumption and utilization by Heliothis virescens
TLDR
The effect of parasitism on the ability of H. virescens larvae to utilize ingested food was partially reduced by parasitism, and larvae parasitized by a normal female were less efficient than non-parasitized larvae in digesting food. Expand
