“…This mite causes severe damage on tomato crops (Solanum lycopersicum Linné) in eastern and western African countries (Sibanda et al 2000;Saunyama and Knapp 2003;Azandémè Hounmalon et al unpublished results). Besides its invasive nature, T. evansi has replaced the native spider mite species, Tetranychus urticae Koch (Trombidiformes: Tetranychidae), T. ludeni Zacher (Acari: Tetranychidae) and the broad mite Polyphagotarsonemus latus Banks (Trombidiformes: Tarsonemidae) in Benin (Adage et al 2007;Martin et al 2010), hence posing new pest management challenges. Biological control of this mite in tomato plant is difficult because of its unsuitability for the development of natural enemies (Kennedy 2003;Zhang 2003;Simmons and Gurr 2005).…”

Visual, vibratory, and olfactory cues affect interactions between the red spider mite Tetranychus evansi and its predator Phytoseiulus longipes

Phytoseiulus longipes Evans (Mesostigmata: Phytoseiidae) is an exotic predator widely used in biological control programs for the red spider mite Tetranychus evansi Baker & Pritchard (Acari: Tetranychidae) in East Africa. However, little is known about the cues mediating this prey/predator interaction. Here, we performed behavioral assays to test the involvement of visual, vibratory, and olfactory cues using a combination of dead/living insects enclosed in either perforated or non-perforated transparent/opaque capsules. We monitored insect responses with a video tracking system and analyzed the data with Ethovision software. Our results showed avoidance behavior of T. evansi in the presence of live P. longipes through visual, vibratory, and olfactory cues. P. longipes was attracted by vibratory and olfactory cues emitted by T. evansi. The composition of volatiles from T. evansi was identified by GC/MS as methyl salicylate (MeSA), linalool, beta-caryophyllene, octanoic acid, decanoic acid, dodecanoic acid, tetradecanoic acid, hexadecanoic acid, and octadecanoic acid. Our behavioral assays with predatory mites in a Y-tube olfactometer revealed that among the identified volatiles, only MeSA, linalool, and MeSA + linalool attracted P. longipes. The implications of these findings for the control of T. evansi are discussed

“…Almost all of the mites in our samples belonged to T. evansi, while those reported as major horticultural pests in Benin (Adango et al, 2007;Martin et al, 2010), i.e. T. urticae, T. ludeni and P. latus, were not found in any of the samples.…”

“…However, these vegetable crops, and particularly tomato, are often attacked by many pests and pathogens (Schippers, 2004). Until recently, the main phytophagous mites reported on these crops were Tetranychus urticae Koch, Tetranychus ludeni Zacher and the broad mite Polyphagotarsonemus latus Banks (Adango et al, 2007;Martin et al, 2010). However, in 2008, outbreaks of Tetranychus evansi were observed on tomato and eggplant in the vegetable growing area of S em e-Podji (Martin, personal communication).…”

“…In view of its at least partial effects on crop pests, application of Jatropha oil or its phorbol ester fraction could be complementary with other control methods such as impregnated nets [94]. Actually, such a technique should be cost-effective on high-value crops such as vegetables or “concentrated” products such as or stored produce.…”

The Phorbol Ester Fraction from Jatropha curcas Seed Oil: Potential and Limits for Crop Protection against Insect Pests

The physic nut shrub, Jatropha curcas (Euphorbiaceae), has been considered as a “miracle tree”, particularly as a source of alternate fuel. Various extracts of the plant have been reported to have insecticidal/acaricidal or molluscicidal/anthelminthic activities on vectors of medical or veterinary interest or on agricultural or non-agricultural pests. Among those extracts, the phorbol ester fraction from seed oil has been reported as a promising candidate for use as a plant-derived protectant of a variety of crops, from a range of pre-harvest and post-harvest insect pests. However, such extracts have not been widely used, despite the “boom” in the development of the crop in the tropics during recent years, and societal concerns about overuse of systemic chemical pesticides. There are many potential explanations to such a lack of use of Jatropha insecticidal extracts. On the one hand, the application of extracts potentially harmful to human health on stored food grain, might not be relevant. The problem of decomposition of phorbol esters and other compounds toxic to crop pests in the field needing further evaluation before such extracts can be widely used, may also be a partial explanation. High variability of phorbol ester content and hence of insecticidal activity among physic nut cultivars/ecotypes may be another. Phytotoxicity to crops may be further limitation. Apparent obstacles to a wider application of such extracts are the costs and problems involved with registration and legal approval. On the other hand, more studies should be conducted on molluscicidal activity on slugs and land snails which are major pests of crops, particularly in conservation agriculture systems. Further evaluation of toxicity to natural enemies of insect pests and studies on other beneficial insects such as pollinators are also needed.
