Potential of biological control agents against Tuta absoluta (Lepidoptera: Gelechiidae): current knowledge in Argentina.

The South American tomato leafminer Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) is an endemic neotropical pest that causes significant economical losses in tomato, (Lycopersicon esculentum L.; Solanales: Solanaceae) production (Desneux et al. 2011). Injury is caused by the larvae that mine leaves and fruits, mainly on solanaceaeous species, and eventually facilitates plant pathogen invasion (EPPO 2005). Native to South America, T. absoluta has recently invaded Europe and it is spreading across Africa and Asia (Desneux et al. 2011), being presently in at least 63 countries. Because of its high invasive potential T. absoluta also causes concern to other countries where T. absoluta is considered a quarantine pest, and where it has not yet been recorded (USDA-APHIS 2011; Zlof & Suffert 2012).

In Argentina, pest management to protect tomato, including tactics against T. absoluta, involves weekly or bi-weekly pesticide treatments (Desneux et al. 2011). Currently, other complementary techniques, like pheromone trapping and applications of Bacillus thuringiensis, are starting to be used by producers as more sustainable forms of pest management (Luna et al. 2012a).

Limited attempts to employ other biological tactics against T. absoluta in Argentina have dealt with the use of imported egg parasitoids (Riquelme Virgala & Botto 2010). However, the results are still preliminary and we still cannot conclude that their commercial implementation in tomato crops is a possibility.

Several natural enemies of T. absoluta have been reported to occur naturally in tomato crops under various cultural practices in Argentina (Desneux et al. 2010; Luna et al. 2012b). Therefore, there is potential value in selecting those native species that are most effective and promising candidates for developing biological control programs.

In this article, we summarize past work and present recent original findings concerning several natural enemies of T. absoluta in tomato crops in Argentina.


Our initial research on natural enemies of T. absoluta took into account their abundance and seasonal synchronization with the pest as the main criterion for selecting species as biocontrol candidates. Subsequently, our studies included additional species of the T. absoluta enemy complex so as to have a thorough understanding of how they interact.

Larval Parasitoids

The parasitoid complex reported for the larval stage of T. absoluta consists of approximately 20 hymenopteran species (Colomo et al. 2002; Luna et al. 2007; Luna et al. 2012b). Yet, the koinobiont endoparasitoid Pseudapanteles dignus (Muesebeck, 1938) (Hymenoptera: Braconidae) and the idiobiont ectoparasitoid Dineulophus phthorimaeae (De Santis, 1983) (Hymenoptera: Eulophidae) accomplish over 50% of natural parasitism and exhibit promising attributes for either augmentative or conservation biological control in the native range of T. absoluta (Colomo et al. 2002; Luna et al. 2007; Sanchez et al. 2009; Savino et al. 2012, 2013). They may also be suitable for introduction in the new regions invaded by T. absoluta (Savino et al. 2012).

Pseudapanteles dignus is a solitary larval endoparasitoid of T. absoluta --and also reported for other gelechiids--commonly present in open field and greenhouse tomato crops, whether organic or sprayed with pesticides (Nieves et al. in press). Previous studies indicated that P. dignus exhibits some life history and ecological traits that could potentially limit T. absoluta populations in this crop (Table 1, Luna et al., 2007, 2010; Sanchez et al. 2009). Pseudapanteles dignus parasitizes all larval instars of its hosts. Population parameters estimated by a life table study under laboratory conditions (25 [+ or -] 2[degrees]C, 65 [+ or -] 5% RH, 14:10 h L: D), yielded a developmental time from egg to adult of 36 days (Nieves 2013; Nieves et al. in press). Female reproductive strategy was moderately synovigenic and time-limited, with a mean egg load of 52 eggs ready to be laid at the emergence of the adult, and a mean fecundity of 192 eggs throughout its adult life (Nieves et al. in press). On average, females laid eggs until the 20th day of adult life, and 50% of the total eggs were laid within the first 6 days (Luna et al. 2007; Nieves et al. in press). Mean parasitism per female (calculated as the total number of parasitized larvae during the female life span divided by the total number of offered larvae) was 47%. Although superparasitism was observed in the laboratory (30%), it rarely occurred in the field (10%) (Nieves 2013). Cohort studies in the laboratory revealed a pre-imago survival rate (egg to pupa) of 38%. Highest mortality occurred at the larval stage, and encapsulation by the host was identified as the main reason (Nieves 2013; Nieves et al. in press). When a single P dignus larva was present in the host, it could suffer up to 28% encapsulation, but superparasitism (~5 immatures per host) could lead up to 91% encapsulation (Nieves 2013).

Life history traits and population parameters of P dignus showed that it had the potential ability to suppress T. absoluta densities (Nieves et al. in press). The intrinsic rate of natural increase ([r.sub.m]) of P dignus was equal to that of T. absoluta ([r.sub.m] = 0.14), reared under the same experimental conditions (Pereyra & Sanchez 2006), and the instantaneous attack rate ([alpha]') of 0.22 (Luna et al. 2007) was larger than the [r.sub.m] of the pest.

In the field, P dignus showed a considerable ability to attack T. absoluta either at low or high densities (Sanchez et al. 2009). Parasitism by P dignus was density-independent, and thus the probability of being parasitized and the risk of parasitism increased with increasing population densities of T. absoluta (Sanchez et al. 2009). In greenhouse tomato, parasitism exhibited a high pest-parasitoid synchrony throughout the crop cycle. By calculating the impact of parasitism on the pest population by means of comparing the areas under the density curves of both populations throughout the season (as in Carey 1993), we showed that P dignus was able to reduce T. absoluta populations by 33-49% in early tomatoes (Sep to Dec) and up to 64% in late tomatoes (Jan to Jun) (Nieves et al. in press).

The mode of parasitism of D. phthorimaeae contrasted with that of P dignus (Table 1). Tuta absoluta and another gelechiid, Phthorimaea operculella (Zeller), were reported as hosts (De Santis 1983). With an ovigeny index equal to 0 (Savino et al. 2012), its female reproductive strategy was extremely synovigenic. Adult females were anautogenous, i.e., they needed to acquire additional nutrients to mature eggs by destructive host feeding. Host feeding by the wasp paralyzed T. absoluta larvae, causing arrest of further development (Luna et al. 2010; Savino et al. 2012). This requirement to host feed on larvae to develop eggs led to T. absoluta mortality by both host-feeding and larval parasitism. The mean lifetime fecundity of D. phthorimaeae was of 4.15 [+ or -] 0.4 eggs per female and showed a type I functional response; hence this species was found to be an egg-limited parasitoid (Luna et al. 2010; Savino et al. 2012) (Table 1). The potential of D. phthorimaeae as natural enemy of T. absoluta was based not only on the quantity of hosts it could parasitize but also on its host feeding behavior; the latter can caused 30% of extra mortality (Savino et al. 2012).

Pseudapanteles dignus and D. phthorimaeae commonly were observed to occur together in tomato crops in Argentina (Luna et al. 2010; Savino 2014). Therefore, we examined the interspecific relationships between both larval parasitoid species, to determine possible multiparasitism, i.e., the use of a single host individual by 2 or more different species of parasitoids. Pseudapanteles dignus and D. phthorimaeae were found to have an overlapping niche, sharing T. absoluta as their host mostly at the third larval instar (Luna et al. 2010; Savino 2014). Under these conditions, it was expected that the idiobiont ectoparasitoid, D. phthorimaeae, should outcompete the koinobiont endoparasitoid, P dignus, by at least 2 mechanisms (Hawkins 1994). Firstly, by killing heterospecific immatures due to host-feeding of already parasitized T. absoluta larvae. Secondly, by paralyzing T. absoluta larvae upon host feeding and by parasitization, thus removing hosts of P dignus, while the opposite it is not true, i.e., T. absoluta larvae parasitized by P. dignus may remain suitable for D. phtorimaeae (Savino 2014).

Host discrimination ability of D. phthorimaeae including its ability to distinguish P dignus parasitized hosts from unparasitized hosts was experimentally examined as follows: Tuta absoluta larvae were offered to individual endoparasitoid females (P dignus) in a cylindrical plastic box (600 mL) arena for 48 h. After that, these previously exposed host larvae were exposed to individual D. phthorimaeae females of 3 ages (1, 5, and 7 days old). Results indicated that young (3-day old) D. phthorimaeae females tended to attack healthy T. absoluta larvae; however, as each female's age progressed (5 days old and older) multiparasitism frequently occured (Savino 2014). The observed coexistence of both parasitoid species in the field could be promoted by the behavior of D. phthorimaeae to partially reject heterospecifically parasitized larvae. The combined effects of the age of the D. phthorimaeae females and the availability of hosts in a patch where both P dignus parasitized and non-parasitized T. absoluta larvae were already present could have played an important role in the dynamics of the interactions between the 2 parasitoid species.

Field surveys carried out in extensive areas of Argentina during 2009 through 2012 (Figure 1 and Table 2) showed a general spatial host density-independent pattern of parasitism for both parasitoid species occurring together on the same plant, regardless the region. Evidence of low-level and host density-independent multiparasitized T. absoluta were also found, indicating a weakly negative interspecific interaction between both parasitoid species (Savino et al. 2013).

Knowledge of host species and host plants that can provide refugia and alternative food resources for the population growth and maintenance of natural enemies is important in the design of biological control strategies for a pest species. Because of the lack of information related to the host ranges of D. phthorimaeae and P dignus, we initiated a survey on horticultural farms in northeastern Buenos Aires province by means of a centrifugal phylogenetic approach (Wapshere 1974). Solanaceous plants commonly cultivated in the region [tobacco Nicotiana tabacum L., eggplant Solanum melongena L., and sweet pepper Capsicum annuum L.], and spontaneous non-cultivated [such as the fierce thorn-apple Datura ferox L., longflower tobacco Nicotiana longiflora Cav., tree tobacco Nicotiana glauca Graham, lily of the valley vine Salpichroa origanifolia (Lam.) Baill., American black nightshade Solanum americanum Mill., and the sticky nightshade Solanum syssimbrifolium Lam.] were examined during 2013-2014, to detect signs of T. absoluta or damage of other gelechiid species. Leafminer hosts and parasitoids collected were identified and numbers of each per plant species were registered. So far, we recorded P dignus parasitizing T. absoluta on eggplant around the year and sporadically on S. americanum, while D. phthorimaeae was detected on T. absoluta only occasionally on eggplant (Salas Gervassio et al. 2014). This information was indicative that host plant species that are alternatives to L. lycopersicum could be playing a role in the maintenance of natural parasitoids of T. absoluta when this crop is absent.


By means of the sentinel egg technique (Moya-Raygoza et al. 2012), we obtained 2 species of egg parasitoids naturally occurring in tomato crops in Argentina: Trichogrammapretiosum (Riley, 1879) (Trichogrammatidae) and Encarsia porteri (Mercet, 1928) (Aphelinidae) (Luft et al. ms submitted). Trichogramma pretiosum had a broader distribution than the aphelinid wasp, which was collected only in Tucuman (northwestern Argentina). Percentages of parasitism were low (< 5%). When these 2 egg parasitoids co-occurred, 50% of the parasitized T. absoluta eggs were attacked by either one of the 2 species, and superparasitism was not observed.

A survey of tomato crops in northwestern Argentina revealed the presence of a native true bug predating a variety of mobile insects. The species was identified as Zelus obscuridorsis (Stal) (Hemiptera: Heteroptera: Reduviidae) (Speranza et al. 2014). Assays were conducted to assess its capability to prey on various developmental stages of T. absoluta. We found that Z. obscuridorsis preyed on the mobile stages, i.e., free larvae and adults, but did not eat larvae in their mines, pupae or eggs.

Discussion and Future Prospects

Any biological control program should select the best strategy for the use of natural enemies, and this includes a thorough knowledge of suitable biocontrol agents that naturally occur in a given region. Among the natural enemy complex of T. absoluta under study, the biological and ecological characteristics of P. dignus presented here and elsewhere (Luna et al. 2012b) meet various criteria as a potentially good biocontrol agent likely to induce sufficient pest suppression when applied in seasonal augmentative releases in commercial crops. For this reason, we have chosen P dignus to conduct experimental releases in tomato greenhouses, a technique to be used alone or in combination in IPM programs. Like many other Braconidae species, P dignus is quite easy to rear and manipulate under laboratory conditions. Results achieved in our studies allow improved P dignus methods for mass rearing, by reducing the frequency of encapsulation and increasing the survival of the offspring. In addition to developing additional knowledge of P dignus rearing, it would be essential to develop quality control guidelines for mass production.

In relation to the other natural control agents of the tomato moth in Argentina, we have continued to study the impact of their trophic interactions (parasitism, predation, competition, intra-guild predation, etc.) in pest suppression. Although less studied to date, these natural enemies could be important in taking advantage of little exploited host niches, i.e., eggs, mobile larvae, etc., by other species antagonistic to T. absoluta.

A thorough research program towards developing an IPM program for a given species should take into account all relevant natural enemies, as well as consider other co-occurring complexes of pests and beneficial species, under an agro-ecosystem approach. Such an approach would not only allow for the development of the best IPM strategy, but also result in a better understanding of the pest's trophic relationships in a given region.
