Genus Takecallis

Bamboo aphids

Species Overview: Genus Takecallis  Takecallis arundicolens 

Genus Takecallis [Panaphidini]

These are small delicate narrow-bodied aphids. The head has poorly developed antennal tubercles and the clypeus (a large plate on the underside of the head at the base of the rostrum) has a characteristic forward directed tubercle. The antennae may be shorter or longer than body. The ratio of the terminal process of the last antennal segment to its base is slightly less than or about equal to 1. Usually all viviparae are winged. The siphunculi are short and truncate, without a distinct apical flange. The cauda is knobbed and the anal plate is bilobed.

There are five species which do not host alternate but feed on bamboo (Bambuseae). They appear not to have sexual forms, but reproduce all year parthenogenetically. The genus is oriental in origin, but several species are now widely distributed.

 

Takecallis arundinariae (Black-spotted bamboo aphid)

Adults alates of Takecallis arundinariae are whitish, pale yellow or greyish-yellow. The thorax has variably developed longitudinal dark stripes, and the abdomen has a pair of elongate dark patches on each tergite. The third antennal segment is dusky to dark except, at the very base, and has the most proximal secondary rhinarium situated close to its base. Takecallis arundinariae siphunculi are pale and the cauda is pale or dusky. The body length is 1.7-2.4 mm.

 

The black-spotted bamboo aphid is found on the underside of mature leaves of bamboos, especially Arundinaria and Phyllostachys spp. Takecallis arundinariae originates from the Far East (India, China, Japan etc), but has been introduced to many other parts of the world including much of Europe, Australia and North and South America. Sexual forms have been found in Korea, but reproduction is entirely parthenogenetic over much of the world.

 

Takecallis arundicolens (Black-tailed bamboo aphid)

Adult alates Takecallis arundicolens have the abdominal tergites pale, without any dark patches. The cauda is conspicuously black (clearly visible in the picture at the rear of the aphid's abdomen).

 

The black-tailed bamboo aphid feeds on bamboo (Phyllostachys spp. and Sasa spp.) as well as common reed (Phragmites australis) (our own record in the UK). This is an invasive species originally found in China, Japan, and Korea but now also present in Europe and North America.

Acknowledgements

We have made provisional identifications from high resolution photos of living specimens, along with host plant identity. In the great majority of cases, identifications have been confirmed by microscopic examination of preserved specimens. We have used the keys and species accounts of Blackman & Eastop (1994)  and Blackman & Eastop (2006)  supplemented with Blackman (1974) , Stroyan (1977) , Stroyan (1984) , Blackman & Eastop (1984) , Heie (1980-1995) , Dixon & Thieme (2007)  and Blackman (2010) . We fully acknowledge these authors as the source for the (summarized) taxonomic information we have presented. Any errors in identification or information are ours alone, and we would be very grateful for any corrections. For assistance on the terms used for aphid morphology we suggest the figure  provided by Blackman & Eastop (2006).

Alan Outen, 26 May 2014, A Takecallis species on Bamboo

A visit to Langford Garden Centre, Beds, this afternoon produced Phyllaphis fagi on Beech and Dysaphis plantaginea on Apple, so nothing remarkable there. However I then found a few aphids (apterae c 4mm + antennae!) on a Bamboo Fargesia sp. as illustated below. These look to me more like images on the internet of Takedallis arundinacea rather than the T. arundicolens on your website. I would be very interested in your thoughts. I am sorry for limitations in the images. They were very skittish!

Bob, InfluentialPoints:

  • The bamboo aphid is Takecallis arundinariae. So far (at least as of 1984) only 3 Takecallis spp have established here. The only one with paired black streaks is T. arundinariae. Like T. arundicolens, it lives on mature leaves whilst the third species (T. taiwanus) lives on young rolled up leaves.

    We still have not found Takecallis arundinariae - and would love to put a copy of your photo on the website.
