“…They are non-toxic to humans, considered safe to the environment, and can often be mass cultured, formulated and applied with common agricultural practises. Globally, mainly H. bacteriophora, H. marelatus, S. glaseri and S. scarabaei are known to be virulent to white grubs (Klein and Georgis, 1992;Selvan et al, 1993;Ansari et al, 2003;Fuzy, 2003 andGrewal et al, 2005;Bal et al, 2014;Guo et al, 2015), but some, such as S. scarabaei, are difficult to mass-rear Fuzy, 2003 and. Prior to the here-reported study, locally adapted EPNs were searched for in semi-natural and small-holder farming habitats across Rwanda .…”

White grubs are largely unsolved problems in vegetable and tuber production in East Africa. Novel Rwandan as well as international entomopathogenic nematodes (EPNs) were screened in nine laboratory bioassays and two small-scale field trials in 2014 and 2015. Soil-based laboratory bioassays revealed that all EPNs were able to infect Anomala graueri larvae (Coleoptera: Scarabeidae), although a relatively high number of infective juveniles were needed. Rwandan EPNs were as infectious as their corresponding international strains. At 100 infective juveniles per larva, the Heterorhabditis bacteriophora strains (Rwanda14-N-C4a and international H06) as well as the international Steinernema carpocapsae All caused 18 to 22% grub mortality within 7 days compared to the control. At 1000 infective juveniles, both H. bacteriophora strains as well as the Rwandan S. carpocapsae RW14-G-R3a-2 killed 34 up to 58%. The Rwandan Steinernema RW14-M-C2a-3 least performed in the bioassays (2 to 6%). In two Irish potato fields, the into-soil-applied 1 × 10 9 infective juvenile Steinernema RW14-M-C2b-1 per hectare reduced 29 ± 33% and 96 ± 3% of grubs within 30 and 60 days, respectively. About 1 up to 2.5 × 10 9 infective juvenile Steinernema longicaudum X7 per hectare reduced 77 up to 85% of grubs until day 30, respectively, and 82 up to 95% until day 60. Avermectin + Chlorpyrifos tuber coatings reduced 39% of grubs, and Fipronil + Chlorpyrifos reduced 27%, whereas handpicking did not help much. In conclusion, at least Steinernema RW14-M-C2b-1 and S. longicaudum X7 are promising for managing white grubs in tuber production, this is at a rate of at least 1.5 × 10 9 EPNs per hectare, but H. bacteriophora RW14-N-C4a needs further field research. Findings will support the biocontrol product development in Rwanda, including registration if any would be needed for native macrobial biocontrol agents.

Abstract. The Japanese beetle, Popillia japonica Newman, is an introduced pest on Terceira, one of nine islands in the Azorean Archipelago. Research conducted on Terceira indicates that entomopathogenic nematodes in the families Steinemematidae and Het erorhabditidae provide good to excellent control of Japanese beetle larvae, but the species that have been evaluated are not native to the Azores. An efficacious species that is native to the archipelago might provide increased capabilities for persisting and recycling in Azorean soil and weather conditions. Surveys on the islands of Terceira and Santa Maria resulted in the isolation of two Hetero rhabditis strains (Sao Mateus and Praia Formosa) with good larvicidal activity for P. japonica. Initial bioassays conducted with Steinernema glaseri (Steiner) originally from North Carolina against P. japonica third instar larvae and pupae produced LC50 values of 3.2 x 105 infectivejuveniles (IJs)/m2 and 0.9 x 105 IJs/m2, respectively. Comparative bioassays of the native isolates and S. glaseri against P. japonica revealed similar larvicidal activity. The LC5os of the Sao Mateus and Praia Formosa isolates against third instar larvae were 3.64 x 105 and 4.44 x 105 IJs/m2, respectively. The LC50 of S. glaseri ranged from 3.2 to 5.5 x 105 IJs/m2. The higher larvicidal activity of the Azorean Heterorhabditis isolates for P. japonica indicates that native nematodes are as effective as S. gla seri. Heterorhabditid species also have demonstrated ability for persistence and apparent recycling under conditions where sustain able control of this introduced pest is needed. Studies comparing the dispersal behavior of the Heterorhabditis bacteriophora Poinar Sao Mateus isolate with that of S. glaseri and native and exotic strains of Steinernema carpocapsae (Weiser) revealed that the H. bacteriophora isolate demonstrated a greater propensity to disperse than other strains in the presence or absence of P. japonica lar vae. In the presence of a host, a greater proportion of H. bacteriophora and S. glaseri dispersed than either of the two S. carpocapsae strains.

“…In 1994 world-wide nematode sales surpassed $US 10 million. In Europe and the USA, larvae of the black vine weevil Otiorhynchus sulcatus are controlled in strawberries, craneberries, ornamentals and tree nurseries with Heterorhabditis spp., S. feltiae or S. carpocapsae (Georgis, 1992). Treatments in citrus plantations reduce root weevils (Curculionidae) by 50-65% (Downing et al, 1991;Schroeder, 1990Schroeder, , 1992.…”

“…White grubs (Scarabaeidae) in turf can be managed by application of Heterorhabditisspp. (e.g., Georgis &Gaugler, 1991;Klein & Georgis, 1992, Downing, 1994, Sulistyanto & Ehlers, 1996. In China the peach borer {Carposina nipponensus) is an important pest of apples and pears (Jinxian, 1993), and several hundred hectares are already treated with S. carpocapsae (Doeleman, 1990).…”
