Mites belonging to the family stigmaeidae are known predators against the phytophagous mites and small soft bodied insects. A survey was conducted to explore the predatory mite fauna of Punjab (Pakistan), a new predatory mite species of genus Eustigmaeus (Eustigmaeus hooriaae) was collected from Ameen Pur Bangla, 20 miles away north from district Faisalabad (Punjab) from Triticum aestivum (straw husk) by Bilal Saeed Khan and described here in this manuscript. Specimens were mounted on the glass slides with the help of Hoyer’s medium. The drawings of different body parts were made with the help of an ocular grid in a high power microscope. These specimens were compared with the already described species. Ceremonial description, illustration of main body parts, host range and comparison remarks are also given. Eighteen (18) paratype females were collected. Twelve (12) from the same collection data and six (6) were collected from R.Y.Khan from leaf litter. All specimens were deposited in the Acarology Research Laboratory, Department of Agri. Entomology, University of Agriculture, Faisalabad, Pakistan.

INTRODUCTION
Eustigmaeus is one the largest genera of the stigmaeidae and contains more than eighty species. Eustigmaeus was initially a subgenus of the genus Stigmaeus, based on Stigmaeus kermesinus Koch, 1841 (Berlese 1910), but was later raised to the generic level (Oudemans, 1923 a). In the same year Oudemans (1923 b) erected the genus Ledermuelleria, but its definition was literally a repetition of that of Eustigmaeus. The problem had not been resolved in the following 50 years, until Wood (1973) re-examined two specimens named Stigmaeus kermesinus in ...

This article talks about Eurosta solidaginis which is the goldenrod gall fly and its interactions with its natural enemies. The natural enemies that are discussed in this article are Eurytoma gigantea and the E. obtusiventris which are both different types of parasitoid wasps, Mordellistena unicolor which is a beetle and two predatory birds the Dendrocopus pubescens which is the downy woodpecker and Parus atricapillus the black-capped chickadee (Abrahamson, 1989). These natural enemies eat the larvae of the goldenrod gall fly while in the gall. The galls are found on tall goldenrod plants. The goldenrod fly induce ball-shaped galls on the stems of

There are nearly one million species of insects known. Insects are defined by having six legs and a body divided into three segments: head, thorax, and abdomen. Chitin is an organic material that makes up an insects exoskeleton. There are three life cycles of insects, ametabolous or incomplete and paurometabolous or gradual, and homotabolous or complete metamorphosis. These life cycles are important in the aging of insects for aiding in legal investigations, (Houck and Siegel. Entomology).

A PEST analysis is an analysis of the external macro-environment that affects all firms. P.E.S.T. is an acronym for the Political, Economic, Social, and Technological factors of the external macro-environment. Such external factors usually are beyond the firm's control and sometimes present themselves as threats. For this reason, some say that "pest" is an appropriate term for these factors. Let us look at the PEST analysis of the Indian aviation sector:
