The potential of semiochemicals to lure insect pests to a trap where they can be killed with biopesticides has been demonstrated as an eco-friendly pest management alternative. In this study, we tested two recently characterized male-produced aggregation pheromones of the bean flower thrips Megalurothrips sjostedti (Trybom), namely (R)-lavandulyl 3-methylbutanoate (major) and (R)-lavandulol (minor), for their field efficacy. Moreover, compatibility of these pheromones and two other thrips attractants, Lurem-TR and neryl (S)-2-methylbutanoate, with the entomopathogenic fungus (EPF) Metarhizium anisopliae ICIPE 69 has been determined. Our study revealed that the M. sjostedti aggregation pheromones have dose-dependent antifungal effects on the EPF viability, but showed no fungistatic effect at a field-realistic dose for attraction of thrips. (R)-lavandulyl 3-methylbutanoate had similar antifungal effects as neryl (S)-2-methylbutanoate 8 days after exposure; whereas, Lurem-TR had a stronger antifungal effect than other thrips attractants. In the semi-field experiments, all autoinoculation devices maintained at least 86% viability of M. anisopliae conidia after 12 days of exposure. Field trials demonstrated for the first time that (R)-lavandulyl 3-methylbutanoate increases trap catches. Our findings pave a way for designing a lure-and-kill thrips management strategy to control bean flower thrips using autoinoculation devices or spot spray application.

Abstract Background Wildlife reservoirs not only act as a source of infection for vectors but also serve as hosts for the vectors themselves, supporting their populations. Their public health significance in developing countries is of growing importance as a result of zoonotic and enzootic diseases associated with the pathogens they transmit. Therefore, a study was carried out to determine the prevalence of ectoparasites of wild game in Nsukka, southeast Nigeria. Physical examinations were carried out on 143 wildlife, and laboratory identification was employed on the ectoparasites. The collected ectoparasites were identified in the laboratory using literature and with the help of a taxonomist. Results Out of the 143 game examined, 114 was infected with at least one parasite representing about 98.6% of an infestation. Among the parasites identified, Amblyomma spp. showed the highest prevalence of 24.5% at 95% confidential intervals of CI (1.45–3.19)–24.5% (p ≤ 0.05). No difference was observed in the prevalence of the ectoparasites according to sex, except for Ixodes holocyclus. Similarly, no difference was observed in prevalence with reference to age except for Rhipicephalus spp. and Polyplax spinulosa which showed differences. Conclusions The present study provides basic data about the most prevalent ectoparasitic arthropod among game in Nsukka, southeast Nigeria, which requires an evaluation of its zoonotic control measures. This work can elicit the risk of possible transmission of some zoonotic and enzootic diseases via game. Improving awareness among local people and bushmeat dealers about the risk of contracting a vector-borne disease through wildlife is crucial.
