“…Microbial pesticides consist of viruses, fungi, and bacteria [21]. Biopesticides form only around 5% of the global pesticides [22], while microbial pesticides account for over 75% worldwide [23]. This chapter provides an overview of microbial-based products B. thuringiensis, B. bassiana, H. armigera nucleopolyhedrovirus, M. rileyi and their application to control cotton pests.…”

Cotton (Gossypium hirsutum L.) is the most produced natural fibre worldwide, and it contributes significantly to the economy of almost 80 cotton-producing countries. Given the high pest infestation, huge amounts of insecticides have been used in cotton production. However, this has resulted in the development of resistance from primary cotton pests and contamination of the environment. Furthermore, the reduction of beneficial insects and outbreaks of secondary pests have been observed. Many arthropod pests are associated with cotton, most of which belong to the orders Lepidoptera, Thysanoptera, and Hemiptera. Biocontrol agents play a critical role in preventing pests in most cotton-growing areas globally. Biological control of cotton pests forms part of integrated pest management as most of these pests have developed resistance against synthetic pesticides. This chapter focuses on the effects of some of the biopesticides, on cotton insect pests. It examines the control of cotton pests using microbial-based products Bacillus thuringiensis, Beauveria bassiana, Helicoverpa armigera nucleopolyhedrovirus and Metarhizium rileyi. Furthermore, the chapter summarizes the application of microbial biopesticides as well as the advantages and disadvantages of using these biocontrol agents in agriculture.

“…Despite this, Chr. rufilabris is known mainly as aphidophagous (Legaspi et al , 1994; Albuquerque, 2009; Dhandapani et al , 2016), and it is commercialized as a biological control agent of aphids in North America and Europe (Tauber et al , 2000; Pappas et al , 2011; van Lenteren, 2012; Leppla et al , 2018; Perring et al , 2018).

The performance (development and reproduction) of generalist predators can vary greatly among the prey species that they use, and these differences can influence the ability of predatory insects to suppress pest populations. The aim of this study was to compare the performance of larvae of the green lacewing Chrysoperla rufilabris (Burmeister, 1839) by offering 16 species of aphids and by assessing the effects of each species on the survival, larval development time, prey consumption, pupal mass and egg load of adult Chr. rufilabris females taking aphid phylogeny into account. Chrysoperla rufilabris larvae preyed on individuals from all 16 aphid species, but complete development, adult emergence and egg load production were achieved only in seven species. As a general pattern, the best levels of performance were achieved for an aphid clade that includes the soybean aphid, Aphis glycines (Matsumara, 1917), and for a milkweed-feeding species, Myzocallis asclepiadis (Monell, 1879). We found significant phylogenetic clustering for most of the performance traits indicating the aspects of specialization in the diet breadth of Chr. rufilabris despite the fact that this species is considered a generalist aphid predator. These findings can help us to understand the interactions of this species in agroecological food webs, where it is commonly found, and provide insights into why natural, conservation biological control or augmentative releases may succeed or fail.

“…With a worldwide production of about 180 million tons, tomatoes are among the most important vegetable crops worldwide (FAOSTAT, 2020). Tomato crops can suffer severe production losses from mite infestations, such as the broad mite Polyphagotarsonemus latus Banks (Acari: Tarsonemidae), several Tetranychus spider mite species (Acari: Tetranychidae), and the tomato russet mite Aculops lycopersici Massee (Acari: Eriophyidae) (Leppla et al, 2018; Navajas et al, 2012; Vervaet et al, 2021). Growers increasingly utilize integrated pest management (IPM) practices to reduce the input of chemical pesticides (Van Lenteren and Nicot, 2020).…”

“…In the present study, we investigated the potential of P. ubiquitus to control the two-spotted spider mite Tetranychus urticae Koch and the red spider mite Tetranychus evansi Baker & Pritchard (Acari: Tetranychidae). These spider mites cause severe economic damage to tomato crops worldwide (Furtado et al, 2007; Leppla et al, 2018). The former is a cosmopolitan pest, which harms a wide variety of crops.…”

The spider mites Tetranychus evansi Baker & Pritchard and Tetranychus urticae Koch (Acari: Tetranychidae) are key tomato pests worldwide. Biological control of spider mites using phytoseiid predatory mites remains challenging. The glandular trichomes on the tomato leaves and stem severely hamper the movement and establishment of the predatory mites. As a result, smaller predatory mites, able to thrive under the sticky heads of the glandular trichomes, have gained much interest. As some iolinid predatory mites were reported to feed on spider mites, we investigated the potential of Pronematus ubiquitus McGregor to control both T. urticae and T. evansi on tomato plants. On whole tomato plants, P. ubiquitus was able to suppress populations of T. urticae, but not of T. evansi. Based on the marginal number of spider mites killed in laboratory trials, the observed biocontrol effect on full tomato plants might not be due to direct predation but to a plant-mediated indirect impact. The oviposition of T. urticae was found to be significantly lower on tomato leaflets pre-exposed to P. ubiquitus as compared to non-exposed leaflets. The oviposition rate of T. evansi was not affected by previous exposure of the tomato host plant to P. ubiquitus. We demonstrated that P. ubiquitus reduces the population growth of T. urticae on tomato plants. Further large-scale field trials need to confirm the findings of the present study.
