Abstract

This paper reports for the first time the occurrence of Typhlodromus (Anthoseius) transvaalensis (Nesbitt) in India. Morphometric measurements of the Indian specimens collected on an unidentified plant in Ramanagara district of Karnataka are provided along with a redescription of the species, and a comparison with specimens from Japan, Africa, Argentina and La Réunion Island to show similarities and variations in morphological traits of taxonomic importance.


Introduction

The family Phytoseiidae contains predatory mites used in biological control. It comprises three subfamilies: Amblyseiinae, Phytoseiinae and Typhlodrominae. Within the subfamily Typhlodrominae, the genus Typhlodromus contains the highest number of species, and is divided into two subgenera, Typhlodromus (Anthoseius) De Leon and Typhlodromus (Typhlodromus) Scheuten (Chant and McMurtry 1994, 2007). There are 388 described species of Typhlodromus (Anthoseius) in the world (Demite et al. 2020).

Typhlodromus (Anthoseius) transvaalensis (Nesbitt), the species reported herein, is widely distributed in many tropical and subtropical parts of the world, viz. Algeria, Australia, Azerbaijan, Brazil, Cameroon, Cape Verde, China, Colombia, Costa Rica, Egypt, Georgia, Guinea, Hawaii, Indonesia, Israel, Jordan, Kenya, New Caledonia, Panama, Philippines, La Réunion Island, Russia, Singapore, South Africa, Taiwan and USA (Moraes et al. 2004; Ueckermann et al. 2008; Demite et al. 2020). Nesbitt (1951) first described this species from ground peanuts in Transvaal (South Africa) and from Rattus sp. in Florida, USA. It occurs on a great variety of plants (Muma and Denmark 1970), including sugarcane, Saccharum officinarum L., in South Africa (Ueckermann et al. 2008); chilli, Capsicum annuum L., and tomato, Lycopersicum esculentum Mill., in Argentina (Cédola and Castresana 2014); and ribwort plantain, Plantago lanceolata L., and rescuegrass, Bromus catharticus Vahl, in La Réunion Island (Kreiter et al. 2020). It was reported in laboratory cultures of mites such as the phytoseiid Scapulaseius okinawanus (Ehara) (Ehara and Kishimoto 2007), the pyroglyphid Dermatophagoides sp. and the otopheidomenid Nabiseius sp. (Prasad 1968). Kreiter et al. (2020) found this species in rearings of Franklinothrips sp. and of unnamed beneficial insects in La Réunion Island, while Ueckermann et al. (2008) found it in a Galleria sp. colony in Kenya, and on the scale insect Coccus viridis (Green) in Cape Verde. The other habitats from where it was recorded earlier are: donkey's dunghill and chocolates in Israel (Amitai and Swirski 1978), an unlabelled stored commodity in the Philippines (Corpuz-Raros et al. 1988) and soil in South Africa (Ueckermann et al. 2008).

Since the present report of T. (A.) transvaalensis is the first from India, morphometric measurements of the Indian specimens collected on an unidentified plant in Ramanagara district of Karnataka are provided along with a redescription of the species. In addition, morphological traits of the Indian specimens are compared with those reported in redescriptions provided by Ehara and Kishimoto (2007), Ueckermann et al. (2008), Cédola and Castresana (2014) and Kreiter et al. (2020) for specimens collected in Japan, Africa, Argentina and La Réunion Island, respectively. All measurements are given in micrometres (µm).

Male

Not found, probably because this species is known to reproduce by thelytokous parthenogenesis (Kishimoto 2015).

Specimens examined

Twenty females, India: Karnataka, Ramanagara district, Channapatna taluk (subdivision), Vandaraguppe Horticultural Station (12°41'15.4'' N, 77°14'13.6'' E), on an unidentified plant, 29 November 2019, collected by Prakya Sreerama Kumar, deposited in the Mite Repository of ICAR–National Bureau of Agricultural Insect Resources.

Discussion

Table 1 gives a comparison of morphological traits of taxonomic importance for specimens of T. (A.) transvaalensis collected in India, Japan, Africa, Argentina and La Réunion Island.

Table 1. Comparison of morphological traits of taxonomic importance for specimens of Typhlodromus (Anthoseius) transvaalensis collected in India, Japan, Africa, Argentina and La Réunion Island [mean (range) or mean ± SE for Japan; number of specimens in parentheses].

The Indian specimens are the smallest as indicated by the dimensions of dorsal and ventrianal shields. Globally, the Indian specimens have shorter setae, particularly j1, j3, j4, j6, J2, z2, z3, z4, Z4, Z5, s4, s6, S2, S4, r3 and R1 than specimens collected in other countries. On the contrary, z5 and S5 are longer, while j5 has a similar length.

Although the dorsal setae of Indian specimens are sparsely plumose, they do not look like those of the Argentinian specimens described and illustrated as plumose by Cédola and Castresana (2014). The Indian specimens are similar to the Japanese specimens (Ehara and Kishimoto 2007) in regard to the setae J5, z2 and S5, which have a pointed tip.

In regard to the macrosetae of leg IV, the Indian specimens are comparable to that of the African and La Réunionese specimens. It can be concluded that the differences between Indian and other specimens are very likely to correspond to intraspecific variations. It is worth noting that the Indian specimens are closer to the African specimens than to those from other regions.

Forty-one species of the genus Typhlodromus (Anthoseius) are reported from India (Demite et al. 2020), and T. (A.) transvaalensis is the 42nd species to be added to that list.

Typhlodromus (A.) transvaalensis is a type III generalist predator that feeds on mites, insects and pollen (McMurtry et al. 2013). It could complete its life cycle feeding on the eriophyid mites Eriophyes dioscoridis Soliman and Abou-Awad and E. olivi Zaher and Abou-Awad, eggs of the scale insect Parlatoria ziziphus (Lucas) and pollen of Ricinus communis (L.) under experimental conditions (Momen and Hussein 1999). Cañarte et al. (2017) showed that it has high potential to control Polyphagotarsonemus latus (Banks) in Jatropha curcas L. plantations.

Mass production and utilization of this species are planned for biological control in India (Gupta and Sreerama Kumar 2018).
