Stichotrema pasteelsi (Luna de Carvalho, 1956) is redescribed based on the type specimen, other specimens collected by Luna de Carvalho, and an additional collection of specimens from Ghana. Stichotrema szekessyi (Luna de Carvalho, 1959) becomes a junior synonym of S. pasteelsi based on current knowledge of the variation within the species. A checklist of African Stichotrema is provided along with comments on the known distribution of the genus in Africa.
Ten species are added to the leafhopper genus Fusigonalia Young. Six species are from Colombia, including F. lobata, F. chelata, F. clavata, F. spinata, F. delta, and F. bispinata, and four are from Peru, including F. plecta, F. ortha, F. aspra, and F. heppneri. Also included is a description of the female of F. caucaensis Young.
Pseudoscorpions employ phoresy for dispersal, in which one animal attaches to another for transportation. This study documents the occurrence and phoresy by Americhernes aff. incertus (Pseudoscorpiones: Chernetidae) on the fly Fannia canicularis (Diptera: Fanniidae) in a fragment of semi-deciduous seasonal Atlantic Forest, in the state of Pernambuco, northeast Brazil. The pseudoscorpions were found attached to the ventral surface of six individual flies. To our knowledge, no previous studies have shown the presence of Americhernes aff. incertus in the northeast Atlantic Forest and its use of flies as a dispersal method.
We have found a new host plant for the long-horn beetle Agapanthia lateralis Gangl. in the north Turkey in the city Kastamonu and in its surroundings. The adults hatched from stalks of herb Onobrychis hypargyrea Boiss. where larvae were found. The diet of Agapanthia lateralis is broader than previously thought and a larger diversity of host plants can probably enable them to occur in more diverse habitats.
The tropical grasshopper (Usherhopper), Poekilocerus bufonius (Orthoptera: Pyrgomorphidae) is found on several host plants such as Calotropis procera, Aizoon canarense, Zygophyllum simplex and Pulicaria crispa in Saudi Arabia (KSA). Many species of Sarcophagidae and Tachinidae parasitize P. bufonius. Here we present the first published record of Blaesoxipha rufipes parasitizing P. bufonius and the first record of its occurrence in Saudi Arabia. We collected 568 adults of the host from five regions in the Middle West of KSA. These were dissected in order to study the parasitoid distribution, parasitism ratio and sex ratio. The parasitoid occurred in all regions investigated but its incidence gradually decreased from East to West. We found that hopper females were significantly more infested (=32.3%) than males (=18.3%). Also, the number of maggots per infested host ranged from 2 to 11 and averaged 6.7 with a significant difference in the mean number of parasitoids for each infested adult male (=3.8) vs. adult female (=7.7). Parasitoid sex ratio overall was 40.1%:59.1% males to females. Occurrence of this parasitoid in KSA suggests further study to investigate its potential as a biological control agent for more damaging Orthoptera.
Whiteflies (Hemiptera: Aleyrodidae) are some of the most problematic global pests of agricultural crops. Yet, natural enemies help control whiteflies. A field survey was conducted to identify and record the natural enemies associated with whiteflies in Egypt. Fifty-two natural enemies (29 species of parasitoids, 8 species of pathogens, and 15 species of predators) were found attacking or isolated from 14 whitefly species in Egypt. New world records are reported herein for two parasitoids [Encarsia lutea Masi and Eretmocerus mundus (Mercet)] on eight species of whiteflies, and for three predators [Chilocorus bipustulatus L., Chrysoperla carnea (Stephens), and Coccinella septempunctata L.] on a single whitefly species [Siphoninus phillyreae (Haliday)]. In addition, new local records of natural enemies on whiteflies are reported; this is the first local report of six predators and three entomopathogenic fungi of whiteflies in Egypt. This work helps in defining the natural enemies of whiteflies in and near agricultural communities.
The morphology of third instar larvae of Solter ledereri Navás, 1912 is described and figured for the first time using light and scanning electron microscopy. The females were collected from Karacadağ Mountain, Diyarbakir Province, Turkey, and maintained in the laboratory. The different parts of the third instar larvae such as head, mandibles, antennae and types of sensory receptors are described and illustrated.
