Vatiga illudens

(Drake, 1922)

cassava lace bug

Vatiga illudens, commonly known as the cassava lace bug, is a small true in the Tingidae. Native to the Neotropical region, it has recently become an pest in Indonesia, where it threatens cassava production. The feeds on cassava plants, causing characteristic yellow spotting on leaves. Climate-based distribution models identify rainfall patterns as the primary factor governing its potential spread.

Identification

The bears a pair of frontal spines, a diagnostic feature visible under magnification. Infested cassava leaves display small yellow spots with brownish variations on the upper surface. As a lace bug (Tingidae), it likely exhibits the 's characteristic reticulated, lace-like wing covers, though specific morphological details distinguishing it from are not available in the provided sources.

Habitat

Agricultural environments, specifically cassava areas. In Indonesia, high suitability occurs in regions with high precipitation during the coldest quarter and specific temperature patterns during the wettest quarter. The has been recorded in lowland, medium, and highland areas in Bali.

Distribution

Native to the Neotropical region, including the Caribbean (Antigua and Barbuda, Barbados, Cuba, Dominica, Dominican Republic, Grenada, Guadeloupe, Haiti, Jamaica, Martinique, Montserrat, Puerto Rico, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Trinidad and Tobago, Florida USA) and South America (Brazil, Colombia, Ecuador, Guyana, Venezuela). established in Indonesia, with first records from East Java in 2021, subsequently reported in Bali and Central Java. Predicted high suitability zones in Indonesia include South Java, Bali, Nusa Tenggara, Timor, South Sulawesi, and South Papua. Also reported from Mauritius and Reunion in Africa.

Diet

Feeds on cassava (Manihot esculenta). Specific feeding mechanisms or additional plants have not been documented in the provided sources.

Host Associations

Manihot esculenta - primary Cassava; the sole documented plant

Ecological Role

Agricultural pest. In its range in Indonesia, it poses a threat to food security by reducing cassava yields. Serves as prey for a of natural enemies including from Hemiptera, Diptera, Orthoptera, Coleoptera, and Araneae, with 15 species identified as potential agents in Banyumas District, Central Java.

Human Relevance

Significant agricultural pest of cassava, a strategic crop for tropical food security. Requires monitoring and in affected regions. Climate-based predictive models support risk-based management approaches and biosecurity measures.

Similar Taxa

Other Vatiga species may occur on cassava; identification requires examination of frontal spine characteristics and other morphological details

More Details

Invasion history in Indonesia

First reported in East Java Province in 2021, representing a novel invasion outside its native Neotropical range. Subsequently documented in Bali and Central Java, with spatial modeling predicting further spread potential in southern Indonesian archipelago regions.

Climate drivers of distribution

Maximum Entropy modeling identifies precipitation during the coldest quarter (BIO19) as the predictor (66.2-67.4% contribution), followed by temperature during the wettest quarter (BIO8, 18.3% contribution) and precipitation during the wettest month (BIO13).
