“…Several species of Anastatus have been used for biological control of various insect pests in China and elsewhere (Stahl et al 2018), including A. japonicus in China against the litchi stink bug, Tessaratoma papillosa Stål, 1864 (Hemiptera, Tessaratomidae) (Li et al 2014), and more recently A. bifasciatus (Geoffroy, 1785) in Europe against the invasive brown marmorated stink bug, Halyomorpha halys Stål, 1855 (Hemiptera, Pentatomidae) (Hancock et al 2018;Judith et al 2018). As part of studies to discover potentially new biological control agents of C. japonica in China, members of the Institute of Biological Control, Jilin Agricultural University, collected eggs of this species in Gansu, Jilin and Liaoning provinces and reared these in the laboratory for parasitoids.…”

Four species of Anastatus Motschulsky (Hymenoptera, Eupelmidae, Eupelminae) are newly reported as egg parasitoids of the Japanese giant silkworm, Caligula japonica Moore and, as an alternate laboratory host, the Chinese oak silk moth, Antheraea pernyi (Guérin-Méneville) (Lepidoptera, Saturniidae) in China. The four species, A. fulloi Sheng & Wang, 1997, A. gansuensis Chen & Zang, sp. nov., A. japonicus Ashmead, 1904, and A. meilingensis Sheng, 1998, were reared initially from eggs of C. japonica collected in Gansu, Jilin and Liaoning provinces and subsequently cultured in the laboratory on eggs of A. pernyi. An illustrated key to differentiate females of the four species, and males of some of the species is provided. Key features are illustrated, both sexes of the new species are described, and diagnoses of females of the other species are given.

“…Infestation to seed and fruits of litchi is reported by number of lepidopteran species which includes Conopomorpha sinensis Bradley, Conopomorpha litchiella Bradley, Conopomorpha cramerella Snellen (Lepidoptera: Gracillariidae), Cryptophlebia ombrodelta Lower, Cryptophlebia illepida Buttler, Gatesclarkeana erotias Meyrick (Lepidoptera: Tortricidae) and Blastobasis sp. (Li et al,7;Bhatia et al,1;Kumar et al,6). Species composition of fruit borer population in litchi ecosystems has been found to affect the level of damage and timing of incidence in litchi fruits.…”

Fruit borers are the major insect pests of litchi in humid orchard conditions at the time of fruit ripening in Indian subcontinent. The major constraint faced in formulating any management strategies against the borer is the difficulty in identification of the correct species. The litchi fruit borer has low intraspecific variation among the existing borer populations. Molecular approaches have been used to identify various species. In the present study, partial cytochrome oxidase I (COI) sequences were used to understand the phylogenetic relationship among borer complex, and assess their usefulness to identify and classify unknown borer species collected from litchi orchards. All together, 150 specimens of litchi fruit borer from Bihar and Jharkhand were examined and 2 morphologically similar moths of each genus were used for further analysis. Sequence analysis revealed that the intraspecific and interspecific variations ranged from zero to 10.0% and 4.4 to 20.3%, respectively among fruit borer complex. The phylogenetic analysis showed that the borers specimen used in this study clustered in to distinct species-groups designated as Conopomorpha sinensis Bradley, C. litchiella Bradley, Cryptophlebia ombrodelta Lower and Gatesclarkeana spp. Higher intraspecific genetic variation was observed in Conopomorpha species complex as compared to Cryptophlebia species complex. Present study has clearly demonstrated that DNA barcoding is an efficient and accurate method for identification of coexists of borer complex infestation in litchi fruits. Hence, this approach can play important role in formulating viable pest management strategies.

“…1 Introduction 1.1 Modeling the biological control of invasive pests Biological invasions are a major contemporary problem (Pimentel 2011;Garnier et al 2012;Mistro et al 2012;Potapov & Rajakaryne 2013;Wang et al 2013;Savage & Renton 2013) for which few solutions are available, all of which are very costly. The use of natural enemies for the biological control of invading insects is one of the most promising possibilities (Moffat et al 2013;Li et al 2014;Ye et al 2014;Basnet & Mukhopadhyay 2014). As invasion is essentially a spatial process, the potential of natural enemies to stop or even reverse an invasion is of particular interest.…”

Bistability induced by generalist natural enemies can reverse pest invasions

Abstract. Reaction-diffusion analytical modeling of predator-prey systems has shown that specialist natural enemies can slow, stop and even reverse pest invasions, assuming that the prey population displays a strong Allee effect in its growth. Few additional analytical results have been obtained for other spatially distributed predatorprey systems, as traveling waves of non-monotonous systems are notoriously difficult to obtain. Traveling waves have indeed recently been shown to exist in predator-prey systems, but the direction of the wave, an essential item of information in the context of the control of biological invasions, is generally unknown. Preliminary numerical explorations have hinted that control by generalist predators might be possible for prey populations displaying logistic growth. We aimed to formalize the conditions in which spatial biological control can be achieved by generalists, through an analytical approach based on reaction-diffusion equations.The population of the focal prey -the invader -is assumed to grow according to a logistic function. The predator has a type II functional response and is present everywhere in the domain, at its carrying capacity, on alternative hosts. Control, defined as the invader becoming extinct in the domain, may result from spatially independent demographic dynamics or from a spatial extinction wave. Using comparison principles, we obtain sufficient conditions for control and for invasion, based on scalar bistable partial differential equations (PDEs). The searching efficiency and functional response plateau of the predator are identified as the main parameters defining the parameter space for prey extinction and invasion. Numerical explorations are carried out in the region of those control parameters space between the super-and subsolutions, in which no conclusion about controllability can be drawn on the basis of analytical solutions.The ability of generalist predators to control prey populations with logistic growth lies in the bistable dynamics of the coupled system, rather than in the bistability of prey-only dynamics as observed for specialist predators attacking prey populations displaying Allee effects. Analysis of the ordinary differential equations (ODEs) system identifies parameter regions with monostable (extinction) and bistable (extinction or invasion) dynamics. By contrast, analysis of the associated PDE system distinguishes different and additional regions of invasion and extinction. Depending on the relative positions of these different zones, four patterns of spatial dynamics can be identified : traveling waves of extinction and invasion, pulse waves of extinction and heterogeneous stationary positive solutions of the Turing type. As a consequence, prey control is predicted to be possible when space is considered in additional situations other than those identified without considering space. The reverse situation is also possible. None of these considerations apply to spatial predator-prey systems with specialist natural enemies. The consid...
