First known host records for the egg parasitoid Gonatocerus californicus (Hymenoptera Mymaridae)
نویسندگان
چکیده
Two leafhopper (Hemiptera Cicadellidae) hosts are reported for Gonatocerus (Gonatocerus) californicus Girault (Hymenoptera Mymaridae): Exitianus obscurinervis (Stal) and Spangbergiella vulnerata lacerdae Signoret. At El Manantial site in Tucumán Province, Argentina, G. californicus emerged from 7.1% and 90.5% of the parasitized sentinel eggs of the respective host on maize plants. Notes on the biological traits of G. (G.) californicus are provided.

Egg age preference, competitive ability, and behavior of Gonatocerus tuberculifemur (‘new association’ parasitoid) and Gonatocerus ashmeadi (‘old association’ parasitoid) were investigated in the laboratory to determine if one species exhibited competitive superiority. When searching concurrently for Homalodisca vitripennis egg masses, G. ashmeadi consistently outperformed G. tuberculifemur by ...

The egg parasitoid Gonatocerus ashmeadi Girault (Hymenoptera: Mymaridae), was introduced into French Polynesia as a biological control agent to control the invasive plant feeding pest Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae). The short-distance dispersal of G. ashmeadi was monitored as part of the biological control program. G. ashmeadi showed exponential dispersal capacity wi...

Egg maturation and oosorption in Gonatocerus ashmeadi were investigated in the laboratory and the relationship between hind tibia length (HTL) and <12 h egg load, and wing wear and parasitoid age were determined. G. ashmeadi given access to honey-water and hosts, on average, matured 77 eggs in excess of those they were born with. The number of mature eggs in female G. ashmeadi provided honey-wa...

The functional response of two egg parasitoids, Gonatocerus tuberculifemur (Ogloblin) and G. ashmeadi Girault (Hymenoptera: Mymaridae), to varying densities of Homalodisca vitripennis (Germar) (Hemiptera: Cicadellidae) eggs was studied in the laboratory. G. tuberculifemur showed a type II functional response where parasitism increased at a decreasing rate as host egg density increased from 5 to...
