“…The fact that S. eridania and S. cosmioides fed Cry1Ac/Cry1F‐soybean had reduced larval weight and increased developmental time to adulthood is favorable for management. Less healthy larvae with longer development times may make them more susceptible to natural enemies 17 and entomopathogenic agents, 45 which consequently would further reduce population growth, reducing the population density and outbreaks of S. eridania and S. cosmioides in Brazilian agricultural landscapes. Alternatively, the high adoption of Bt soybean with relatively low efficacy against secondary pests such as Spodoptera species may provide opportunities for these species to become more important in soybean.…”

BACKGROUND: Spodoptera eridania (Stoll), S. cosmioides (Walker) and S. albula (Walker) (Lepidoptera: Noctuidae) are considered secondary pests of soybean in South America. The genetically-modified soybean DAS-444Ø6-6 × DAS-81419-2 with tolerance to 2,4-dichlorophenoxyacetic acid (2,4-D), glyphosate and ammonium glufosinate herbicides (event DAS-444Ø6-6) and insect-resistance due to expression of Cry1Ac and Cry1F Bt proteins (event DAS-81419-2) may provide a potential tool for integrated pest management (IPM) of these species in soybean fields. Based on this, we conducted bioassays to evaluate the survival and development of S. eridania, S. cosmioides and S. albula fed on Cry1Ac/Cry1F-soybean leaf tissue. RESULTS: Spodoptera eridania and S. cosmioides fed on Cry1Ac/Cry1F-soybean showed longer developmental time, lower larval and egg to adult survival compared to those fed on non-Bt soybean, reducing the population growth of these species. Spodoptera albula also had lower larval survival and number of insects that reached adulthood on Cry1Ac/Cry1F-soybean. However, no significant effects of Cry1Ac/Cry1F-soybean on population growth parameters were detected in this species. CONCLUSIONS: Soybean with stacked events DAS-444Ø6-6 × DAS-81419-2 expressing Cry1Ac/Cry1F Bt proteins provide population suppression of S. eridania and S. cosmioides. However, this Bt soybean had minimal effects on S. albula, and is unlikely to have negative population-level effects on this species. It is expected that under field conditions, other control tactics must be integrated with Cry1Ac/Cry1F-soybean for the management of these Spodoptera species.

“…They show considerable potential in controlling different forest pests (Augustyniuk-Kram & Kram 2012). EPH are known to infect almost all insect species and developmental stages, above all Hemiptera, Lepidoptera, Diptera, Coleoptera, Orthoptera and Hymenoptera (Ramanujam et al 2014;Khan & Ahmad 2015). It is assumed that Beauveria bassiana alone can kill more than 750 different insect species (Ghikas et al 2010).…”

Coniferous forests in Europe have a considerable number of pests that attack trees of all ages from youngest up to oldest ones. One of them is the large pine weevil Hylobius abietis. This species is widespread in Europe and occurs from warm southern areas (Spain) up to northern countries (Sweden, Finland). Larvae of this species do not cause damage, they help in the decomposition process of stumps and roots. Adults are harmful as they consume bark of young coniferous seedlings, above all of spruce and pine. One adult can consume on average 75 mm2 of bark per day. Individuals can live up to 4 years, and during their lives they can damage and kill several tens of coniferous seedlings. Traditional chemical protection of seedlings against this pest is and will gradually be more and more restricted or forbidden. In this review, we describe this method as well as all other alternative methods including biological protection. We estimate that H. abietis causes annual damages in Europe of almost 120 million € and damages several tens of thousands of hectares of young forest stands.

“…However, only about a dozen of these entomopathogenic fungal species are available for pest management at the grower level (Hajek and St. Leger, 1994) and others are effective against a wide range of insect pests including Spodopteran species (Purwar and Sachan, 2005). For insect control, Beauveria bassiana is known to be the most common, highly effective and widespread entomopathogenic fungus worldwide (Khan and Ahmad, 2015). Ruiz-Nájera et al ( 2013) isolated Nomurae arileyi from 38 larval corpses of S. frugiperda.…”

The objective of this article is to review the knowledge on Spodoptera frugiperda and the possible management strategies against the pest to identify research areas for its integrated management. A review of the literature shows that S. frugiperda (Lepidoptera: Noctuidae) has been causing considerable damage to maize and many other crops since its detection in several African countries and it is one of the most destructive pests to have entered Africa in the 21st century. Several control methods have been developed against this pest ranging from the use of synthetic plant protection products to agroecological and biological controls. The biology, distribution and control methods of the pest are well documented. However, Integrated Management of the pest remains a major challenge; the main control is chemical. Innovative research on biological and ecological control methods will help to overcome the constraints and promote sustainable management of the pest. Very few scientifically proven alternatives adapted to the African context exist. This gap needs to be filled by further research considering aspects such as the inventory of local natural enemies, the performance of key parasitoids and the potential of local entomopathogens for sustainable and integrated management of the pest.
