Importance of feeding behaviour on life cycle in the zoophytophagous bug Dicyphus geniculatus
Dicyphus geniculatus (Fieber) (Heteroptera Miridae) is a Mediterranean mirid that has been observed in public green areas in towns of eastern and western provinces of Spain feeding on whiteflies and thrips on Dianthus caryophyllus L. carnations. In this article, the relative importance of feeding...

| description | Dicyphus geniculatus (Fieber) (Heteroptera Miridae) is a Mediterranean mirid that has been observed in public green areas in
towns of eastern and western provinces of Spain feeding on whiteflies and thrips on Dianthus caryophyllus L. carnations. In this
article, the relative importance of feeding behaviour with respect to the duration of nymphal development and nymphal survival,
as well as reproduction, was investigated. Nymphs of Bemisia tabaci (Gennadius), larvae of Frankliniella occidentalis (Pergande)
and carnation plants introduced into a 50 × 50 × 50 cm methacrylate box, together with adults mirids, in a climate-controlled
chamber (25 ± 1 °C, 60 ± 5% HR, 16:8 h L:D photoperiod) were used to analyse feeding behaviour. In particular, data on realised
fecundity, sex ratio and adult longevity were analysed. Realised fecundity differed significantly with respect to prey availability
(F1, 267 = 44504.92; p ≤ 0.001). The sex ratio did not differ from 1(♂♂):2(♀♀+♂♂) with respect to feeding regimes [“with
B. tabaci prey” (37/53+37 = 0.41), χ2 = 1.434, df 1, p = 0.231, “with F. occidentalis prey” (42/50+42 = 0.46), χ2 = 0.200, df 1,
p = 0.655] or prey type (B. tabaci or F. occidentalis, χ2 = 0.564, df 1, p = 0.453). Adult longevity differed significantly in terms of
prey availability (F2, 534 = 58.89, p ≤ 0.001) and longevity differed for each sex within each feeding regime (F1, 534 = 14.13;
p ≤ 0.001). D. geniculatus can survive on a host plant diet exclusively but could not complete its development in the absence of
supplemental prey food, indicating that D. geniculatus requires an animal component in its diet. Other zoophytophagous dicyphines
are successfully used as beneficials in integrated pest management in horticultural crops. Thus, D. geniculatus has a potential
role in the biological control of carnation pests, and therefore may be a promising pest biological control agent, thus contributing
to urban area sustainability. |
