Bactrocera kandiensis

Previous scientific names: Bactrocera sp. nr B. dorsalis (D)

Diagnosis

Morphological – adult

Features include:

  • face fulvous with a pair of large oval black spots
  • scutum black except sometimes brown below and behind lateral postsutural vittae, around mesonotal suture, inside postpronotal lobes, around prsc. setae and on anterocentral margin
  • postpronotal lobes yellow (anteromedial corners red-brown)
  • notopleura yellow
  • mesopleural stripe slightly wider than notopleuron dorsally
  • narrow parallel sided lateral postsutural vittae ending at ia. seta
  • medial postsutural vitta absent
  • scutellum yellow with a moderately broad black basal band
  • legs with femora fulvous with dark fuscous on outer apical 2/3 of fore femora, inner apical 1/2 of mid and inner apical 1/3 of hind femora, fore tibiae fuscous, mid tibiae fulvous and hind tibiae dark fuscous
  • wings with cells bc and c colourless, microtrichia in outer corner of cell c only, a narrow fuscous costal band confluent with R2+3 and remaining narrow around margin of wing to end between extremities of R4+5 and M, a narrow fuscous cubital streak
  • supernumerary lobe of medium development
  • abdominal terga III-V orange-brown with a narrow transverse black band across anterior margin of tergum III but not covering lateral margins, a very narrow medial longitudinal fuscous to dark fuscous band over all three terga (occasionally interrupted at intersegmental lines) and very narrow fuscous to dark fuscous anterolateral corners on terga IV and V, a pair of oval orange-brown shining spots on tergum V
  • abdominal sterna dark coloured
  • posterior lobe of male surstylus short
  • female with aculeus tip needle shaped (Drew and Romig 2013).

Molecular

Host Range

Polyphagous. The pest status of this species in unclear. Drew and Romig 2013 and Allwood et al. 1999 only record this species from mango and Garcinia spp.

However, Tsuruta et al. 1997 records it from 21 hosts from 13 plant families including Anacardiaceae, Caricaceae, Clusiaceae, Laureaceae, Moraceae, Myrtaceae, Oxalidaceae and Rutaceae.

Major commercial hosts:

  • Garcinia species
  • Mangifera indica (mango)

Similar species

Similar to B. caryeae in possessing very narrow lateral vittae and dark markings on the apices of the femora, but differs in having a defined T on the abdomen (instead of wraparound) and in having blunt ended vittae (sometimes taper in B. caryae) (Royer pers. comm. 2017)

It is also similar to B. dorsalis but has narrower vittae, dark markings on the apices of the femora and a broad basal band on the scutellum.

It is similar to some specimens of the Australian rainforest species B. endiandrae but has narrower vittae, a very narrow anal streak, dark markings on the apices of the femora and a broad basal band on the scutellum.

Pest Status

  • Exotic
  • A major pest of mangoes and is probably responsible for much of the damage generally attributed to B. dorsalis in Sri Lanka
