Thrips palmi is a polyphagous pest, especially of Cucurbitaceae and Solanaceae. It has been reported as an outdoor pest of aubergine (Solanum melongena), Benincasa hispida, Capsicum annuum, cotton (Gossypium spp.), cowpea (Vigna unguiculata), cucumber (Cucumis sativus), Cucurbita spp., melon (Cucumis melo), peas (Pisum sativum), Phaseolus vulgaris, potato (S. tuberosum), sesame (Sesamum indicum), soyabean (Glycine max), sunflower (Helianthus annuus), tobacco (Nicotiana tabacum) and watermelon (Citrullus lanatus). It can infest flowers, for example of citrus in Florida (USA) or mango in India. It can also infest weeds (e.g. it was reported on Vicia sativa, Cerastium glomeratum and Capsella bursa-pastoris in unheated glasshouses in Japan Nagai & Tsumuki, 1990). In Japan, it does not attack tomato (Solanum lycopersicum), whose leaves have been shown to contain a feeding deterrent (Hirano et al., 1994); in the Caribbean, however, T. palmi has been recorded on outdoor tomato crops (Pantoja et al., 1988). In glasshouses, economically important hosts are aubergine, Capsicum annuum, chrysanthemum (Chrysanthemum x morifolium), cucumber, Cyclamen, Ficus and Orchidaceae. Within the EPPO region, T. palmi could infest, for example, Capsicum annuum, cucurbits, S. melongena, and ornamentals under glass.

T. palmi was described in 1925 from Sumatra (Indonesia) (Karny, 1925). A few years later this species was discovered as far west as Sudan, and as far north as Taiwan. Since 1978, extensive outbreaks are reported yearly from Southern Japan (Sakimura et al., 1986). Since 1985 it has been spreading in the Caribbean region following its introduction in Guadeloupe and Martinique (Bournier, 1986; Denoyes et al., 1986; Guyot, 1988), and since 1988 there have been several limited outbreaks in the EPPO region which have been subsequently eradicated.

BIOLOGY 2022-09-22

In Japan, T. palmi can only overwinter on outdoor vegetation in a small part of Southern Japan (Yoshihara, 1982). Tsumuki et al. (1987) analysed the cold hardiness of T. palmi and concluded that it could not survive winter conditions in southern Honshu, and thus in most of Japan. However, another study (Nagai & Tsumuki, 1990) reported no reduction of adult populations at temperatures as low as -3 to -7°C in an unheated glasshouse in Japan. In Europe, an EFSA (2019) study concluded that most of Southern Europe had suitable climatic conditions for the establishment of T. palmi on outdoor vegetation.

At 25°C, the life cycle from egg to egg lasts 17.5 days. The life cycle differs little from that of most phytophagous Thripidae: the adults emerge from the pupa in the soil and move to the leaves or flowers of the plant, where they lay their eggs in the plant tissues. The second-stage larva enters the soil, develops there and pupates, thus completing the cycle. The specialized mouthparts are adapted for sucking. As a consequence the type of plant injury caused by feeding is always sucking damage. The life cycle and population dynamics of T. palmi in Japan have been reviewed by Kawai (1990a). At 25°C, the net reproductive rate, female fecundity and daily oviposition rate reached their maxima, the values for the last two parameters being 59.6 eggs per female and 3.8 eggs per day, respectively (Kawai, 1985). In Taiwan, the optimum temperature for population growth was found to be 25-30°C, and the number of generations possible in Central Taiwan was estimated as 25-26 per year (Huang and Chen, 2004). Likewise Cermeli and Montagne (1993) recorded that at 26°C, on leaves of Phaseolus vulgaris, the life cycle was 11.5 days, the net reproduction rate 18.3, the generation time 27.3 days and the intrinsic rate of natural increase was 0.125 individuals per female per day.



T. palmi can be found in buds, cracks or crevices on host plants. At inspection, silvery feeding scars on the leaf surface, especially alongside the midrib and veins, can be seen. Damage has been described in Martinique by Denoyes et al. (1986) on aubergine and cucurbits. On fruits, this thrips causes corky lesions, that are characteristic on aubergines.

Heavily infested plants are characterized by a silvered or bronzed appearance of the leaves, stunted leaves and terminal shoots, and scarred and deformed fruits. Individuals may be found on all parts of many kinds of plants (Sakimura et al., 1986).


T. palmi can easily be mistaken for T. flavus Schrank or T. tabaci Lindeman, which are, economically less important thrips, commonly found on flower or vegetable crops. For the distinction between the three species, microscopic examination is necessary. T. palmi is characterized by the length of the female (about 1.3 mm compared with 1.7 mm in T. flavus), clear yellow body, with blackish setae, abdominal tergite II with four lateral setae, interocellar setae outside the ocellar triangle (T. flavus: interocellar setae inside), abdominal tergite VIII with complete comb in both sexes (T. flavus (male): comb incomplete). Strassen (1989) provides an account of characters distinguishing T. palmi from widespread thrips species in Europe. Confusions are also possible with other thrips species, such as Frankliniella occidentalis, F. schultzei, Thrips nigropilosus.

The EPPO Diagnostic Protocol for T. palmi (EPPO Standard PM 7/3, 2018) and ISPM 27 (FAO, 2010) provide recommendations on how to detect and identify the pest.

Detection and inspection methods

Thrips palmi is a small insect which is not easy to detect on plants, but its damage is visible: leaves silvered or bronzed, punctuations, corky marks on the fruits. The pest can be present on leaves, buds, fruits, flowers, but also in the soil as pupae. On cucurbits (e.g. melon, cucumber, watermelon), adults and larvae are notably present in the buds.

The eggs are impossible to observe because they are tiny and inserted into plant tissues. Fruits of aubergine, one of the preferred hosts of T. palmi, may harbour larvae and adults under the calyx. Within crops, T. palmi can be detected with blue or white sticky traps (Kawai, 1983). It is possible to detect T. palmi and evaluate population levels in the crops by taking leaves and placing them in a Berlese funnel.


T. palmi has only moderate dispersal potential by itself (it can fly on short distances and it can be easily transported by wind), but is liable to be carried on fruits, or plants for planting of host species, or in packing material. For example, it can be transported over long distances under the calyx of aubergines. For example T. palmi has been intercepted in several EPPO countries on consignments from Guadeloupe, Martinique, Mauritius, and Thailand. An analysis of interceptions of T. palmi in Europe and USA showed that the majority of them have been recorded on ornamentals (e.g. orchid cut flowers), aubergines and Momordica charantia, as well as on plants for planting (Vierbergen, 2001).


Economic impact

T. palmi, a polyphagous feeder with a wide host range, quickly builds up heavy infestations causing severe injuries. Both larvae and adults feed gregariously on leaves (first along the midribs and the veins), stems (particularly at or near the growing tips), flowers (among the petals and developing ovary) and fruits (on the surface), leaving numerous scars and deformities, and finally killing the entire plant. In tropical countries, T. palmi damages outdoor crops but in Japan, large-scale infestations of glasshouses have occurred (for example, on aubergine). In Hawaii (USA), T. palmi damages ornamental orchids. In Guadeloupe, T. palmi has had disastrous economic effects on cucurbit crops (melon, cucumber) and solanaceous crops (aubergine, Capsicum) which could be completely destroyed by this pest. Aubergine exports fell from 5000 tonnes in 1985 to 1600 tonnes in 1986. In Martinique, 37% of the vegetable crops of the two main cooperatives were attacked and 90% of aubergine crops (Guyot, 1988). In India, T. palmi is the vector of groundnut bud necrosis tospovirus, in Japan and Taiwan it vectors watermelon silvery mottle tospovirus (Honda et al., 1989; Yeh et al., 1992; Yeh & Chang, 1995). These viruses are closely related to tomato spotted wilt virus (TSWV), but T. palmi has not yet been demonstrated to vector TSWV. Other viruses which are known to be transmitted by T. palmi are calla lily chlorotic spot virus (Chen et al., 2005), capsicum chlorosis virus (Melzer et al., 2014), melon yellow spot virus (Kato et al., 2000), tomato necrotic ringspot virus (Seepiban et al., 2011), and watermelon bud necrosis virus (Gosh et al., 2021).


T. palmi is difficult to control chemically in the field and especially in glasshouses due to its resistance to some active substances or perhaps because of the inaccessibility of a large proportion of the population as a consequence of a cryptic life cycle and feeding habits (Cannon et al., 2007). Insecticides such as imidacloprid and pyrethroids have been used, but may have serious effects on natural enemies (Nemoto, 1995). In Martinique (Bon & Rhino, 1989), profenofos, avermectin and carbofuran were the most effective insecticides on outdoor vegetables, while oxamyl, carbofuran, NTN, tokuthion and sulprophos gave the best results in cages (Ryckewaert, 1990). However, the majority of these products are highly toxic and not authorized on vegetable crops. In Guadeloupe, numerous chemical tests have been carried out but the results have been generally disappointing (Etienne & Van Waetermeulen, 1989). In trials under glass in Japan, none of the (repeated) insecticide applications gave more than 80% mortality. Supplementary cultural and mechanical methods were required to control the pest (Yoshihara, 1982; Kawai, 1990b). T. palmi populations can be monitored with blue sticky traps or water-tray traps (Layland et al., 1994). 

Many natural enemies have been identified across the world, such as predators belonging to different families (e.g. Anthocoridae (notably Orius spp.), Miridae, Lygaeidae, Berytidae, Coccinellidae, Aeolothripidae, Phlaeothripidae, Thripidae, Phytoseiidae), a few parasitoids and entomopathogenic fungi (Cox et al., 2006). Preliminary studies have been carried out concentrating on Orius spp. (Hemiptera: Anthocoridae) (Nagai et al., 1988; Kawai, 1995) and Amblyseius spp. (Acarina: Phytoseiidae) (Kajita, 1986). At present, biological control of T. palmi by releasing predators, parasitoids or entomopathogens is not sufficiently efficient as it concerns mainly open field crops, and it is difficult to breed these beneficials in large quantities. In Japan, Kawai and Kitamura (1987) recommended IPM systems on cucumber in plastic greenhouses. IPM methods including prophylaxis, use of chemicals with specific active ingredients and natural biological control were developed in Martinique in the early 1990s and have enabled reduction of populations to acceptable levels (Ryckewaert, 1991). T. palmi has become rare in open field crops in recent years in the Lesser Antilles and other countries, mainly through the use of natural biological control and by avoiding the use of those pesticides which have a negative effect on beneficials (Ryckewaert, 2014). 

Phytosanitary risk

In the EPPO region, T. palmi presents a serious threat to a wide variety of crops grown under glass, and many interceptions have been reported in this region (Viebergen, 2001). It could possibly establish on field crops in southern areas or in greenhouses of the EPPO region, as occurred for Frankliniella occidentalis (EPPO/CABI, 1996) which was originally considered to present a risk only under glass. Although T. palmi is not apparently a vector of TSWV, it does vector closely related viruses. In view of the situation which developed in Europe with F. occidentalis and TSWV, the vector capabilities of T. palmi merit close attention.


Because T. palmi is difficult to detect at low densities in consignments, inspections should be made during the growing season at the place of production. Alternatively, or additionally, consignments and/or the place of production should be treated against the pest.
