Pests, microorganisms and parasites are responsible for significant losses crops and especially fruits and vegetables, which threaten food human. Côte d’ivoire, the first provider of pineapple (Ananas comosus) fresh on European market is facing in recent years to a drastic drop in production to several factors including the action of microorganisms during storage.

The struggle Chemical although effective drawbacks. This study aims using the Bacillus subtilis strain GA1 in biological control against germs responsible for alteration pineapple fruit in côte d’ivoire. A sample of twenty-five pineapple which has been used five healthy pineapple and five altered were used for the isolation of microorganisms and fifteen healthy pineapples were used for other tests. The main agents Fungal spoilage isolated pineapple fruit in this work were Aspergillus sp., Rhizopus sp., Fusarium sp., And Candida sp. The pathogenicity tests also confirmed that the isolated fungal strains are responsible for the pineapple fruit rotting.

The tests antagonists conducted in the presence of B. subtilis GA1 against fungi isolated showed inhibition rate of 81.2% for Aspergillus sp (s), 69% for Aspergillus sp (a), 64% for Rhizopus sp., and 57.14% for Fusarium sp. protection tests on fruits from biomass of B. subtilis GA1 helped preserve fruits over a period of fourteen (14) days with no mushrooms in the heart of the fruit.

The present study was designed to record the distribution of ground dwelling spider genera among mustard crop at Okara district. Sampling was made from Brassica compestris crop through pitfall traps. Equal number of traps were placed in three rows e.g. along the boundary, middle of the field and centre of the field.

Each trap was filled with mixture solution of alcohol and glycerin (70:30%) along with few drops of kerosene oil. After 5 days interval sample traps was collected and spider specimens were washed with distilled water and permanently stored in labeled glass vials, and brought into the Pest Control Laboratory, Department of Zoology, Wildlife and Fisheries, University of Agriculture, Faisalabad. Thereafter, each spider specimen was identified according to the taxonomic material and internet source. Identified data was analyzed statistically to quantify their spatial distribution. Maximum spatial distribution of spider population was documented in middle transect than boundary and centre of the mustard crop. It was also observed that temperature, humidity and prey availability were the major factors that effecting the spider population. Population variations were recorded during the months of February, March and April in 2015, due to rise of temperature, decrease of humidity and availability of prey. Conclusively, spiders have some correlation with suitable local conditions or habitat. More over, spiders are cost effective, functionally significant and play important role in regulating decomposer population.
