在匈牙利发现了黑核桃新种--胡桃叶潜蝇，报道为欧洲新记录种。黑核桃(Juglans ngra(L.))、白核桃(J.cinerea(L.))和亚利桑那州核桃(J.Major(Torr.))，后两种为核桃核桃寄主新记录种。在山核桃(Carya cordiformis(Wangenh.)K.Koch)和高加索翼果(Ptercarya fraxinifolia(Lam).SPACH.)(一新寄主植物)，以及普通核桃(Juglans Regia L.)有趣的是，荧光藻被认为在被引入欧洲后进行了寄主植物的转移，而核桃隐杆藻显然没有。胡兰氏吸虫在匈牙利有三代人。这两个物种的秋季世代产生的地雷比春季世代多得多。从核桃小蜂饲养的膜翅目寄生蜂标本1例。核桃隐翅虫和核桃隐翅虫的幼虫、地雷和成虫可以很容易地区分开来，并给出了区别和图解。首次描述了核桃隐杆线虫的生殖器。
The Nearctic leafminer of black walnut Coptodisca juglandiella (Chambers, 1874) was found in Hungary and reported as new for Europe. Larvae were found in leafmines on black walnut (Juglans nigra (L.)), white walnut (J. cinerea (L.)) and Arizona walnut (J. major (Torr.)); the latter two Juglans species are new host plant records for C. juglandiella. Mines of Coptodisca lucifluella (Clemens, 1860), another Nearctic invader, were found on leaves of bitternut hickory (Carya cordiformis (Wangenh.) K.Koch) and Caucasian wingnut (Pterocarya fraxinifolia (Lam). Spach.) (a new hostplant record), in addition to common walnut (Juglans regia L.). Interestingly, C. lucifluella is thought to have performed a host plant shift after its introduction into Europe, whereas C. juglandiella apparently did not. Coptodisca juglandiella has three generations in Hungary. The autumn generations of both species produced many more mines than the spring generations. One hymenopteran parasitoid specimen was reared from C. juglandiella. Larvae, mines and adults of C. juglandiella and C. juglandiella can be easily distinguished, differences are presented and illustrated. The genitalia of C. juglandiella are described for the first time.
