In this study, we define a Kantorovich type generalization of W. MeyerKönig and K. Zeller operators and we will give the approximation properties of these operators with the help of Korovkin theorems. Then we compute the approximation order by modulus of continuity.

In this present paper, we introduce a new and simple integral modification of the Meyer-Konig and Zeller Bezier type operators and study the rate of convergence for functions of bounded variation. Our result improves and corrects the results of Guo (J. Approx. Theory, 56 (1989), 245–255 ), Zeng (Comput. Math. Appl., 39 (2000), 1–13; J. Math. Anal. Appl., 219 (1998), 364–376), etc.

Microloxia herbaria (Hübner, [1813]) and Scopula luridata (Zeller, 1847) are reported for the first time from Maltese Islands. Distribution habits of adult larvae included. A name is proposed these new records.

In this paper we will demonstrate a Voronovskajatype theorems and approximation theorems for GBS operators associated to some linear positive operators. Through particular cases, we obtain statements verified by the GBS operators of Bernstein, Schurer, Durrmeyer, Kantorovich, Stancu, BleimannButzer-Hahn, Mirakjan-Favard-Szász, Baskakov, Meyer-König and Zeller, Ismail-May.

This study reports 30 species of Lepidoptera previously known from either the Palearctic or the Nearctic that are newly recorded as Holarctic. For 28 of these species, their intercontinental distributions were initially detected through DNA barcode analysis and subsequently confirmed by morphological examination; two Palearctic species were first detected in North America through morphology and...

Two species, Athrips albimacula Oh & Li, sp. nov. and A. lingchuana nov., are described as new; two pruinosella (Lienig Zeller, 1846) spiraeae (Staudinger, 1871), newly recorded for China. Images of adults genitalia the above four species illustrated.

Use of Indian mustard (Brassica juncea (L.) Czern.) as a trap crop for management of diamondback moth, Plutella xylostella (L.), and leafwebber, Crocidolomia binotalis Zeller, was tried on an experimental farm and farmers’ fields. Preliminary studies indicated that planting of 15 cabbage rows followed by paired mustard rows to manage both pests was useful. The first mustard row is sown 15 days ...
