“…The more humid and moist environmental conditions in the broccoliÀYSC habitat may have been conducive for the growth and development of fungal pathogens (Tanada and Kaya, 1993). Ekesi et al, (1999) found that mortality of flower thrips, Megalurothrips sjostedti (Trybom), caused by applications of the entomopathogen Metarhizium anisopliae (Metschnikoff) Sorok., was significantly higher in cowpea intercropped with maize than in monoculture also treated with this fungus. The effect of agricultural diversification on the incidence of entomopathogens merits greater attention.…”

Two field experiments were conducted in Hawaii to determine the responses of lepidopteran pests and their associated natural enemies to broccoli (Brassica oleracea), grown in monoculture or interplanted with chili pepper (Capsicum annuum), or yellow sweetclover (YSC) (Melilotus officinalis). The population responses of Artogeia rapae and Trichoplusia ni to habitat types were not consistent during the field trials. Additionally, their reactions to habitat diversification differed according to non-host plant species. For example, Trichoplusia ni densities were significantly lower in the broccoliÀYSC habitat contrasted with the broccoliÀpepper habitat on most sampling dates. Similarly, the proportion of plants damaged by Hellula undalis was significantly lower in the broccoliÀYSC habitat contrasted with broccoliÀpepper habitat. Findings from the study, suggest that biological control agents (e.g., spiders, parasitoids, and entomopathogens) are the most significant factors influencing the abundance of A. rapae in habitat type and that these agents inflict greater mortality on A. rapae in diculture than monoculture habitats.

The susceptibility of Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) to selected strains of the entomopathogenic fungi Beauveria bassiana (Balsamo) Vuillemin and Metarhizium anisopliae (Metschnikoff) Sorokin was evaluated through bioassays with direct immersion or foliar exposure under laboratory conditions. Results showed that A. planipennis adults were susceptible to B. bassiana and M. anisoplae. Significant time-mortality response was found for each isolates. Isolate B. bassiana GHA killed A. planipennis adults at a faster rate compared with other isolates tested, with the lowest average time-to-death values. The LC50 values estimated under direct immersion method ranged from 1.7 x 10(5) to 1.9 x 10(7), 3.5 x 10(4) to 5.3 x 10(5), and 4.1 x 10(3) to 2.9 x 10(5) conidia/ml for B. basissiana and from 3.2 x 10(6) to 1.1 x 10(7), 4.5 x 10(3) to 4.5 x 10(5), and 1.4 x 10(2) to 1.2 x 10(5) conidia/ml for M. anisopliae at 4, 5, and 6 d after treatment, respectively. By days 5 and 6, B. bassiana GHA outperformed all other isolates tested except ARSEF 7234, followed by ARSEF 7152, 6393, and 7180. Significant concentration-mortality response was also observed for two B. bassiana GHA formulations, BotaniGard ES and Mycotrol O, and M. anisopliae F52 when insects were treated through foliar exposure. The LC50 values ranged from 114.5 to 309.6, 18.4 to 797.3, and 345.3 to 362.0 conidia/cm2 for BotaniGard, Mycotrol, and M. anisopliae F52, respectively. Based on the results of these bioassays, the efficacy of both B. bassiana GHA formulations and M. anisopliae F52 were similar against adult A. planipennis. The potential use of entomopathogenic fungi for management of A. planipennis in North America is discussed.

Vegetables are one of the important crops which could alleviate poverty and malnutrition among the smallholder farmers in tropical Asia and Africa. However, a plethora of pests limit the productivity of these crops, leading to economic losses. Vegetable producers overwhelmingly rely on chemical pesticides in order to reduce pest‐caused economic losses. However, over‐reliance on chemical pesticides poses serious threats to human and environmental health. Hence, biopesticides offer a viable alternative to chemical pesticides in sustainable pest management programs. Baculoviruses such as nucleopolyhedrovirus (NPV) and granulovirus (GV) have been exploited as successful biological pesticides in agriculture, horticulture and forestry. Maruca vitrata multiple nucleocapsid NPV (MaviMNPV) was found to be a unique baculovirus specifically infecting pod borer on food legumes, and it has been successfully developed as a biopesticide in Asia and Africa. Entomopathogenic fungi also offer sustainable pest management options. Several strains of Metarhizium anisopliae and Beauveria bassiana have been tested and developed as biopesticides in Asia and Africa. This review specifically focuses on the discovery and development of entomopathogenic virus and fungi‐based biopesticides against major pests of vegetable legumes and brassicas in Asia and Africa. © 2019 Society of Chemical Industry
