Describing Shapes of the Wings of the Mango Leafhopper, Idioscopus Clypealis (Lethierry) Collected from Different Orchards

Mark Ronald S. Manseguiao, Cesar G. Demayo

Farm management methods have always used pesticides to mitigate the pests and improve the crop yields. This study investigated the population structures of Mango leafhopper, Idioscopus clypealis in mango orchards unsprayed or sprayed with pesticides. The analysis of the populations was based on the wing shapes used by insects to fly. Geometric and morphometric techniques were used to analyze the shapes of the forewings of the pest. The results of the thin plate spline image showed asymmetry in the left and right wings in the two sexes of the insect pest. The relative warp analysis showed that wing shapes of insects in the unsprayed orchard had a mean shape close to the consensus wing shape unlike those populations where there was a routine application of pesticides. The differences in wing shapes of the populations collected from unsprayed and sprayed orchards were argued to be due to the effects of pesticides.

Entomology and Applied Science Letters is an international peer reviewed publication which publishes scientific research & review articles related to insects that contain information of interest to a wider audience, e.g. papers bearing on the theoretical, genetic, agricultural, medical and biodiversity issues. Emphasis is also placed on the selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance. Papers on non-insect groups are no longer accepted. In addition to full-length research articles and reviews, the journal publishes interpretive articles in a Forum section, Short Communications, and Letters to the Editor. The journal publishes reports on all phases of medical entomology and medical acarology, including the systematics and biology of insects, acarines, and other arthropods of public health and veterinary significance.

Call for Papers
Entomology and Applied Science Letters supports the submission of entomological papers that contain information of interest to a wider reader groups e. g. papers bearing on taxonomy, phylogeny, biodiversity, ecology, systematic, agriculture, morphology. The selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance is also important. Distinguished entomologists drawn from different parts of the world serve as honorary members of the Editorial Board. The journal encompasses all the varied aspects of entomological research. This has become the need felt in scientific research due to the emphasis on intra-, inter-, and multi-disciplinary approach.
