Abstract EN

The mirid bug D.

neglectus neglectus attacks onions in the coastal area in Syria and causes economic damage.

The morphology of various life stages of the bug and its alternative host plants were studied during the period January-April, 2015 and 2016.

The results obtained indicated that the onion bug had five nymphal instars.

The average body length of the first nymphal instar was 1.29 ± 0.18 mm, the second 2.94 ± 0.10 mm, the third 3.87±0.16 mm, the forth 4.62 ± 0.19 mm, the fifth 5.22 ± 0.17 mm, and the male measured 7.26 ± 0.14 mm and the female 6.55 ± 0.50 mm in length.

The host plants garlic (Allium sativa L.), narcissus (Narcissus tazetta.

L.), grand chrysanthemum (Chrysanthemum coronarium L.) and groundsel (Senecio vulgaris L.) were recorded as new hosts for this bug in Syria.
