“…Nutrition has bearing on overall health of an insect, and suboptimal nutrition may mediate effects of fungal entomopathogens. For example, Thungrabeab et al (2006) reported that two species of thrips reared on cotton or Saintpaulia spp. (Gesneriaceae) were much less susceptible to B. bassiana than those reared on bean, leek (Allium ampeloprasum var.…”

Ecological factors in the inundative use of fungal entomopathogens

2009

Fungal entomopathogens have been developed in numerous countries as biocontrol agents with more than 100 mycoinsecticide products commercially available in 2006. The chief, perhaps sole, use of these mycoinsecticides has been as inundative agents, within a chemical paradigm. Large numbers of propagules are applied in an attempt to overwhelm by brute force many of the factors that keep a pathogen in nonepizootic equilibrium with its host. This review attempts to summarize what we know about the abiotic and biotic factors that affect the efficacy of these mycoinsecticides in both foliar and soil applications. Sunlight, humidity, temperature, and phylloplane-associated factors can affect both immediate efficacy and persistence on plants. Likewise, soil texture-moisture interactions, temperature, and a host of biotic factors can affect mycoinsecticides in the soil. Despite much research, our understanding of these ecological aspects is imperfect, especially in a holistic, dynamic sense.

“…There have been trials to establish aromatic insecticides from various plant species to control onion thrips at field and greenhouse conditions and the following have been recommended: Artemisia arborescens, Azadirachta indica L., Chrysanthemum cinerariifolium, Datura stramonium, Dodonaea angustifolia L., Dianthus caryophyllus, Melaleuca alternifolia, Nicotiana glauca, Origanum majorana, Ocimum gratissimum, Rosmarinus officinalis, and Tagetes minuta (Fitiwy et al 2015;Omosa et al 2016;Prabhu et al 2011;Shiberu & Negeri 2014;van Tol et al 2007).…”

“…Repellents are products of secondary metabolites, used as olfactory messengers to interfere, and discourage insects from landing or movement onto plant surface. In New Zealand, onion thrips was repelled by R. officinalis essential oil and deterred by D. angustifolia, O. gratissimum, and O. majorana essential oils, and the controlling efficiency against onion thrips was about 71-87% (van Tol et al 2007).…”

“…Beauveria bassiana, Metarhizium anisopliae, Lecanicillium (Verticillium) lecanii/muscarium, Entomophthora parvispora, Entomophthora thripidum, Paecilomyces lilacinus, and Neozygites parvispora have been tested against onion thrips (Abe & Ikegami 2005;Annamalai et al 2013;Carl 1975;Ezzati-Tabrizi et al 2009;MacLeod et al 1976;Maniania et al 2003;Samson et al 1979;Wu et al 2016). According to Thungrabeab et al (2006) about 36 isolated entomopathogenic fungi species successfully lowered the onion thrips population; however the pathogenic efficiency varied among the species. In another report, B. bassiana significantly lowered the population of larval and adult stages of onion thrips under greenhouse conditions (Wu et al 2014).…”

The Major Biological Approaches in the Integrated Pest Management of Onion Thrips, Thrips Tabaci (Thysanoptera: Thripidae)

Thrips tabaci Lindeman is a cosmopolitan and polyphagous insect pest. It is known worldwide and recorded on more than 300 plant species. T. tabaci is a key pest of onion and several other crops, and its control is vital to the production and profitability of crops. If onion thrips population is not controlled, damage can reduce yield volume and quality. In addition to direct damage to the host plants, T. tabaci has been characterized as an asymptomatic vector of three devastating tospovirus species, such as Tomato spotted wilt virus, Iris yellow spot virus, and Tomato yellow ring virus. For this reason, several synthetic insecticides were used for control. However, these insecticides bring unwanted effects, like pesticide resistance, elimination of nontarget species, environmental pollution, and threats to human health. To solve the negative consequences of insecticides, biopesticides, such as plant secondary metabolites, entomopathogenic viruses, bacteria, fungi, and nematodes, have been recognized as effective alternatives. The use of plant-based insecticides and entomopathogenic control methods gained more attention in integrated pest management. Their strong side is lack of residues, saving beneficial insects and minimizing air and water pollution. Plant-derived compounds and entomopathogenic biological control agents offered a variety of biological modes of actions against onion thrips, such as repellency, feeding deterrence, anti-oviposition, fecundity deterrence, metamorphosis inhibition, and parasiting the host’s body.

“…Entomopathogenic fungi are currently being investigated for the control of many important insect pests on various crops around the world and some are commercially available (Thungrabeab, Blaeser, and Sengonca 2006). Carl (1975) reported that Neozygites parvispora has been found frequently on T. tabaci but under field conditions, the fungus was less successful than in the greenhouse.…”
