New Pest

A new psyllid pest of ficus, Macrohomotoma gladiata (Hemiptera: Sternorrhyncha: Psylloidea), is reported for the first time from North America (California, U.S.A.). Notes on another adventive psyllid species that has been collected from ficus in California, Homotoma ficus, are given, together with a list diagnostic features that separate between M. gladiata and H. ficus.

Eleven Species

Eleven species of free-living Copepoda are dealt with in this paper. One of them (Eucyclops lilljeborgi (Sars)) is recorded for the first time in North America. Three species (E. prionophorus Kiefer, Megacyclops latipes Lowndes, and Acanthocyclops carolinianus Yeatman) have not been recorded in Canada before, while three species (A. venustoides Coker, A. venustoides bispinosus Yeatman, and Paracyclops affinis (Sars)) have not hitherto been recorded in Ontario. Four species considered rare, namely Diaptomus wilsonae Reed, Diacyclops navus Herrick, Macrocyclops ater Herrick, and Mesocyclops leuckarti Claus, but found to be widely distributed are briefly referred to. Notes are given of the diagnostic features and distribution of each species.

AbstractEcological data, distribution records, comments, and diagnostic features are given for eight European species of Longitarsus Latreille introduced into North America: L. ferrugineus (Foudras); L. succineus (Foudras); L. luridus (Scopoli); L. jacobaeae (Waterhouse); L. ganglbaueri Heikertinger; L. pratensis (Panzer); L. pellucidus (Foudras); and L. rubiginosus (Foudras). The last two species are reported for the first time in North America.

First Time

Drosophila suzukii (Diptera, Drosophilidae) is an exotic species, endemic to Asia and currently a pest to small and stone fruits in several countries of North America and Europe. It was detected in 2013 for the first time in South America, in the south of Brazil. Unlike most drosophilids, this species deserves special attention, because the females are capable of oviposit inside healthy fruits, rendering their sale and export prohibited. Despite the confirmed existence of this species in different states of Brazil, this insect is yet been to be given the pest status. Nevertheless, the mere presence of this species is enough to cause concern to producers of small fruits and to justify further investigation for it’s control, especially chemical control for a possible change in status. Therefore, the goal of this work was to evaluate, in laboratory, mortality of D. suzukii adults and ovicidal effect when exposed to different insecticides registered for species of the Tephritidae and Agromyzidae families in different cultures. The insecticides deltamethrin, dimethoate, spinosad, fenitrothion, phosmet, malathion, methidathion, and zeta-cypermethrin resulted in mortality to 100 % of the subjects three days after the treatment (DAT). Regarding the effects over eggs, it was  established that the insecticides fenitrothion, malathion, and methidathion deemed 100 % of the eggs not viable, followed by phosmet and diflubenzuron, which also caused elevated reduction in the eclosion of larvae two DAT.

First Time

SummaryThe Devonian brachiopod Tropidoleptus is recognized for the first time in South Africa. It is present in the lower part of the Witteberg Group at four widely separated localities. Data regarding the stratigraphical range of the genus elsewhere, combined with information on recently described fossil plants and vertebrates from underlying strata of the upper Bokkeveld Group, suggest that a Frasnian or even Givetian age is reasonable for the lower part of the Witteberg Group. The recognition of Tropidoleptus in a shallow water, near-shore, molluscan association, at the top of the South African marine Devonian sequence, is similar to its occurrence in Bolivia, and suggests a common Malvinokaffric Realm history of shallowing, prior to later Devonian or early Carboniferous non-marine sedimentation. It is noteworthy that Tropidoleptus is now known to occur in ecologically suitable environments around the Atlantic, but is absent from these same environments in Asia and Australia. Tropidoleptus is an excellent example of dispersal in geological time — first appearing in northern Europe and Nova Scotia, then elsewhere in eastern North America and North Africa, followed by South America and South Africa, while continuing in North America.

AbstractChaetocnema concinna (Marsham, 1802), a European flea beetle, is reported for the first time from Canada. Preliminary collection data indicate that it may feed on the same host plants as in Europe. It has been collected to date in Prince Edward Island, Nova Scotia, and Maine.

Procteria (Pachyprocteria) vermifera n. sp. is described from the upper part of the York River Formation (Gaspé Sandstones Group), lower Eifelian (brachiopod Amphigenia Zone), Rimouski County (Quebec, Canada). This new species is considered part of a new lineage of Pachyprocteria characterized by the presence of interstitial corallites. This study reveals for the first time that the granules on the lower (proximal) side are distributed irregularly, their density being higher in the central area of this side than at the periphery. The unusual association of the tabulate coral Procteria (Pachyprocteria) with the “worm” Hicetes is pointed out. The record of the new species adds to the known paleogeographic distribution of Pachyprocteria in North America (Laurussia).
