Eurygaster integriceps Put., 1881 (Hemiptera: Scutelleridae)’in yumurta parazitoiti Trissolcus semistriatus (Nees, 1834) (Hymenoptera: Scelionidae)’da konukçuyu ayırt etme ve süperparazitizm üzerine bir değerlendirme

Abstract

Trissolcus semistriatus (Nees, 1834) (Hymenoptera: Scelionidae) Eurygaster integricepsPut., 1881 (Hemiptera: Scutelleridae)’in en yaygın ve önemli yumurta parazitoitidir. Bu çalışma, 2016 yılında laboratuvarda tercihli ve tercihsiz denemelerle T. semistriatus’un kendisi ya da diğer bir dişisi tarafından parazitlenmiş E. integricepsyumurtasını ayırt etme durumunu tespit etmek ve ergin parazitoit ve konukçu yoğunluğunun parazitlenme üzerindeki etkisini saptamak için yürütülmüştür. Dişi parazitoit kendisi tarafından parazitlenmiş konukçu yumurtasını süperparazitlememiştir. Ancak ilk parazitlenmeden sonraki 1 saat içinde diğer bir dişi tarafından parazitlenmiş yumurtaların %18’inin (%81’lik parazitizm oranından önemli olarak daha düşük oranda) süperparazitlendiği görülmüştür. İlk parazitlenmeden 24 saat sonrasındaki tercihli denemelerde kaydedilen %23’lük orana göre tercihsiz denemelerde önemli olarak daha düşük %1’lik bir oranda süperparazitizm meydana gelmiştir. Parazitizm artan konukçu yumurtası sayısı ile önemli oranda düşmüş, ancak artan parazitoit yoğunluğu ile değişmemiştir. Bu nedenle, T. semistriatus’un parazitlenmiş konukçu yumurtasını ayırt edebildiği, dişilerin ilk parazitlenmeden 48 saat sonrasına kadar önceden parazitlenmiş konukçu yumurtalarıyla karşılaştığında nadiren bir süperparazitizm meydana geldiği kanısına varılmıştır.

An evaluation on host discrimination and superparasitism in Trissolcus semistriatus (Nees, 1834) (Hymenoptera: Scelionidae), egg parasitoid of Eurygaster integriceps Put., 1881 (Hemiptera: Scutelleridae)

Abstract

Trissolcus semistriatus (Nees, 1834) (Hymenoptera: Scelionidae) is the most common and important egg parasitoid of Eurygaster integricepsPut., 1881 (Hemiptera: Scutelleridae). This study was conducted to determine discrimination E. integricepseggs parasitized by either self or a conspecific female of T. semistriatusin choice and no-choice tests, and to establish effect of adult parasitoid density and host density on parasitism in the laboratory in 2016. Female parasitoids did not superparasitize self-parasitized host eggs. However, superparasitism of 18% (significantly lower than the 81% parasitism rate) of the eggs parasitized by another female occurred within 1 h of first parasitism. Superparasitism was significantly lower at 1% in no-choice tests than the 23% recorded in choice tests within 24 h of first parasitism. Parasitism significantly decreased with increasing host egg number, but parasitism did not change with increasing parasitoid density. Therefore, it is concluded that T. semistriatuscan discriminate between parasitized and unparasitized host eggs, with superparasitism infrequent when females encounter preparasitized host eggs within 48 h of first parasitism.
