Climate is a key factor affecting the insect population dynamics, including <jats:italic>O. lybicus<\/jats:italic>. There are limited studies of <jats:italic>O. lybicus<\/jats:italic> relating to microclimate. The aim of this study was to investigate the efficiency of the various humid thermal indices (HTIs) and daily accumulation of temperature and humidity to model the relationship with <jats:italic>O. lybicus<\/jats:italic>.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>The highly infested locations showed a strong relationship with cumulative daily mean relative humidity (RhC<jats:sub>m<\/jats:sub>), followed by daily minimum temperature (T<jats:sub>min<\/jats:sub>) for pooled data over two seasons. The next best regression models for the relationship between the infestation and climate was with the absolute factors, daily maximum humidity (Rh<jats:sub>mx<\/jats:sub>) and daily minimum humidity (Rh<jats:sub>min<\/jats:sub>), compared with HTI<jats:sub>m\/m<\/jats:sub> (ratio of mean humidity to mean temperature) for the autumn season. The best regression model for the spring season was daily mean humidity (Rh<jats:sub>m<\/jats:sub>) and daily maximum temperature (T<jats:sub>max<\/jats:sub>).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>Daily cumulative temperature was the best predictive model for <jats:italic>O. lybicus<\/jats:italic> infestation on date palms, considering the microclimate data at each location separately. The predication model points to the areas that are prone to infestation and need focus for monitoring and allocation of management resources. \u00a9 2019 Society of Chemical Industry<\/jats:p><\/jats:sec>","DOI":"10.1002\/ps.5422","type":"journal-article","created":{"date-parts":[[2019,3,21]],"date-time":"2019-03-21T03:40:33Z","timestamp":1553139633000},"page":"3060-3069","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Humid\u2010thermal index for a new management approach of <i>Ommatissus lybicus<\/i>"],"prefix":"10.1002","volume":"75","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0211-8876","authenticated-orcid":false,"given":"Rashid","family":"Al Shidi","sequence":"first","affiliation":[{"name":"Ecosystem Management, School of Environmental and Rural Science University of New England  Armidale New South Wales Australia"},{"name":"Directorate General of Agriculture and Livestock Research Ministry of Agriculture and Fisheries  Muscat Sultanate of Oman"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lalit","family":"Kumar","sequence":"additional","affiliation":[{"name":"Ecosystem Management, School of Environmental and Rural Science University of New England  Armidale New South Wales Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Salim AH","family":"Al\u2010Khatri","sequence":"additional","affiliation":[{"name":"Directorate General of Agriculture and Livestock Research Ministry of Agriculture and Fisheries  Muscat Sultanate of Oman"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,4,19]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/978-94-017-9707-8_6"},{"key":"e_1_2_7_3_1","unstructured":"Pariona A.Leading Countries Growing Dates (Fresh Date Palm Fruits).
