Abstract
Postmortem Findings in Captive Sand Gazelle and Arabian Oryx at Al-Wusta Wildlife Reserve, Oman
Highlights
The current study was conducted to develop a new approach for revealing egg-laying behaviour of alfalfa weevil, Hypera postica (Gyllenhal) (Coleoptera: Curculionidae) laying in alfalfa fields at late fall
A new scale developed by CHAID indicated that height of eggs was found higher as the plant height increased from Node 1 to Node 10, and in MARS, number of egg cluster and plant height affected height of eggs (P
Clusters of eggs and eggs in clusters found in the plant stem were counted and the distance from soil level to height of eggs laid by the alfalfa weevil pest was measured
Summary
The current study was conducted to develop a new approach for revealing egg-laying behaviour of alfalfa weevil, Hypera postica (Gyllenhal) (Coleoptera: Curculionidae) laying in alfalfa fields at late fall. In the prediction of height of eggs, CHAID (Chi-square t Automatic Interaction Detection) and MARS (Multivariate Adaptive Regression Splines) algorithms were irs implemented for describing egg laying behaviour of the alfalfa weevil and giving an idea on minimizing loss of the fields, in practice. A line lfalfa weevil, Hypera postica (Gyllenhal) (Coleoptera: Curculionidae) is the pest that seriously damages alfalfa in Turkey and in many regions of the n world where alfalfa is cultivated (Metcalf and Luckman, O 1994; Blodgett and Lenssen, 2004). The pest gives a generation annually and population by grazing and cutting in fall season, meaning lays their eggs at two periods i.e. fall and spring seasons. The pest gives a generation annually and population by grazing and cutting in fall season, meaning lays their eggs at two periods i.e. fall and spring seasons. that the damage reduces at the fresh period of the alfalfa
