“…1) when only parasite eggs occurred in the host (Table 1). To date, parasite eggs have not been shown to release hormones into the host although they are known to take up amino acids [26], and larvae take up ecdysteroids [22] and probably other substances from the host's hemolymph.…”

This i s the first report of a juvenile hormone (JH) in the Caribbean fruit fly, Anastrepha suspensa (Diptera: Tephritidae). JH Ill was identified in whole body extracts of L3 (final instar) larvae and pharate pupae (PhP) by using a physicochemical method. JH Ill was also found in PhP superparasitized (up to 11.3 ? 3.5 S.D. parasitedhost) by the solitary wasp Biosteres longicaudatus (Hymenoptera: Braconidae) and in first instars of the parasite. The levels of JH Ill in hosts were up to 15 x higher than those of the controls. The JH esterase (JHE) levels in the hemolyrnph of I-day-old PhP controls were significantly ( P < 0.05) higher than those of superparasitized individuals. These results suggest that the elevated JH Ill levels induced by superparasitism may arise from JH buildup due either to decreased JHE activitiy to continued synthesis of J H by the ring gland or to secretion of JH Ill by the parasites into the host's hernocoel.

“…Flanders (1942) termed such eggs ''hydropic'' because they swell upon oviposition and were assumed to absorb the nutrients necessary for embryonic development from the host hemolymph. Ferkovich and Dillard (1986) demonstrated the capacity of the hydropic eggs of the braconid parasitoid, Microplitis croceipes, to absorb radiolabeled amino acids, but not proteins, from the hemolymph of their hosts.…”

“…Flanders (1942) described two functional types of egg chorion for parasitic waspsÑanhydropic and hydropic. Anhydropic eggs have enough yolk for subse- quent embryonic development, whereas hydropic eggs do not and absorb nutrients from the host through the chorion (Ferkovich and Dillard 1986). Hydropic eggs occur widely in endoparasitic Hymenoptera.…”

Diadromus collaris (Gravenhorst) is an important pupal parasitoid of the diamondback moth, Plutella xylostella (L.), a major insect pest of cruciferous vegetables worldwide. We studied the development of immature stage of D. collaris by dissecting parasitized hosts in the laboratory at 25 ± 1°C and 50–80% relative humidity. The results show that all immature stages complete their development within the same host in 11≈12 d. The egg is hymenopteriform and appears to be anhydropic. There are four larval instars. The first instar is transparent with a sclerotized rectangular chitinous head capsule and distinct mandibles. Head capsule of the second instar turns into more isosceles trapeziumshaped. The third instar looks similar to the second instar but proportionally much larger. The sclerization and dimension of the fourth instar increases significantly. The pupa is a typical exarate form and lacks a cocoon. All life history was fully documented with detailed photomicrographs. Our study will be useful for understanding the physiological interactions between D. collaris and P. xylostella.
