The banana skipper <em>Erionota torus</em> Evans has recently emerged as a serious pest of banana. In the present study for the first time egg parasitism of <em>E. torus</em> by <em>Ooencyrtus pallidipes</em> (Ashmead), a gregarious parasitoid, is reported from India. The natural percent parasitism observed was 80−82% in the banana field located at Komanal, Shivamogga district, Karnataka. Since this parasitoid has served as an effective biological control agent for <em>E. torus</em> in Mauritius and Taiwan, possibilities are there that it can establish as a potential biological control agent in India as well.

Potential Use

Summary In the period from August to October 2018, 140 specimens of the Spanish slug, Arion vulgaris, were collected from Podbrezje, Slovenia. Slugs were dissected and examined for the presence of parasitic nematodes within the cadavers. Identification of the nematodes was conducted using morphological and molecular techniques and confirmed the presence of Phasmarhabditis papillosa. This is the first record of P. papillosa from the mollusc host, A. vulgaris. Laboratory experiments aimed at testing the efficacy of P. papillosa against A. vulgaris were conducted using nematodes grown in vivo. Nematodes were applied at concentration rates of 50, 100 and 200 nematodes slug−1, respectively. Three weeks following treatment, the mortality of slugs was confirmed in all treatments (50 nematodes slug−1, 37.4 ± 2.7%; 100 nematodes slug−1, 48.4 ± 2.7%; 200 nematodes slug−1, 50.6 ± 2.7%). However, the pathogenesis of P. papillosa was observed first in the treatments with the lowest nematode dose at 4 days after treatments, while a decrease in the feeding behaviour of slugs was noted first in the treatments with the highest nematode dose. Future opportunities for the potential use of P. papillosa as a biological control agent against slugs are discussed. This is the first report of P. papillosa from Slovenia, and of its virulence against A. vulgaris.

A New Species

A new species of Tanaostigmodes (Hymenoptera: Chalcidoidea, Tanaostigmatidae) is described from China—Tanaostigmodes puerariae sp. nov. This is the first record of this family in China. This new species has potential as a biological control agent for control of kudzu, Pueraria lobate, in the U. S., because its preference for making leaf galls on kudzu. It was determined that the wasp has two generations per year, with the second generation overwintering as mature larvae in the gall on leaves that have dropped to the ground. Normally, only one wasp was found per gall, and a single kudzu leaf could have as many as 20 to 50 galls on its surface.

Significant Mortality

Worldwide interest in Phasmarhabditis originates from the successful commercialisation of P. hermaphrodita as a biological control agent against molluscs in Europe. To date, P. hermaphrodita has not been isolated from South Africa and, therefore, the formulated product may not be sold locally. During a survey for mollusc-associated nematodes, P. papillosa was dissected from the slug, Deroceras reticulatum, collected from George, South Africa. The nematode was identified using a combination of morphological, morphometric, molecular and phylogenetic techniques. Virulence tests were conducted which demonstrated that P. papillosa caused significant mortality to the European invasive slug Deroceras panormitanum. Additional data are provided in the morphometrics of the infective juvenile and in the molecular identification, using the mitochondrial cytochrome c oxidase subunit I (cox1) gene. This is the first report of P. papillosa from the African continent and of its virulence against D. panormitanum.

Species Being

Phytoseiidae (Acari: Mesostigmata) is an important family of predatory mites, with some species being commercialized as biological control agents for the control of phytophagous mites and small insects. In Peru, 65 species of this family have been recorded so far, with Amblyseius being the most diverse genus, with 11 species. The aim of this study is to report for the first time the presence of Amblyseius tamatavensis Blommers, 1974 in Peru. In South America, this species has so far been reported only in Brazil and Venezuela. In Peru, A. tamatavensis was found on orange plants [Citrus sinensis (L.) Osbeck] in the district of Pangoa, department of Júnin. In the laboratory, collected specimens were observed to feed on Phyllocoptruta oleivora (Ashmed, 1879) (Acari: Eriophyidae) and Frankliniella occidentalis (Pergande, 1895) (Thysanoptera: Thripidae). Studies to verify the potential of this species as a biological control agent for pests occurring in Peru should be conducted. A key to the Amblyseius species recorded in Peru is presented.

AbstractAbout 130 species of parasitoids and predators are reported, most of them for the first time, to be associated directly or indirectly with the cassava pest Phenacoccus manihoti Matile-Ferrero and its parasitoid, Epidinocarsis lopezi (De Santis), newly introduced into Africa as a biological control agent. About 20 species are common. The species are grouped in 11 guilds, which include the indigenous hyperparasitoids, which originally attacked parasitoids of other mealybugs, the predators with which E. lopezi competes for the same food source and their antagonists.
