Piper nigrum Linn. (Black pepper)  belongs to the family Piperaceae and an economically and medicinally important spice and is a native of Southern India. Leaf marginal gall is transmitted by Liothrips karnyi belonging to family Phlaeothripidae of order Thysanoptera (Thrips). Insect induced galls arise due to growth reaction of plants due to the attack of cecidozoa, also known as zoocecidia. The growth and development of the host plant alter due to the infestation of the insect, which involves certain complex phenomena. The different groups of cecidozoa influence the plants in such a way as to produce galls at different stages in their life history. Most of the cecidozoa cause galls only in their developmental stages, but some of them are capable of inducing galls both in larval as well as adult stages. The crop production in India has been adversely affected due to the infestation of pests. And it is necessary to use different approaches of disease management to curb the infestation, and significant researchers have shown progress to protect the crops in an eco-friendly manner. Piperine exhibits diverse pharmacological activities like antihypertensive, antiplatelets, antioxidant, antitumor, antipyretic, analgesic, anti-inflammatory, anti-diarrheal, antibacterial, antifungal, anti-reproductive, insecticidal activities. In the present investigation, the biological method of disease management of marginal leaf gall transmitted by Liothrips karnyi has been undertaken. The biological control of leaf diseases has been significant on the increased reflection of environmental problems over pesticide uses.

Background: Pepper plants belong to the Piperaceae family with many pharmacological activities. The fruits of these plants have been widely used traditionally for various therapies, one of which is an aphrodisiac. Objective: The purpose of this study was to determine the aphrodisiac activity of the fruits of three pepper plants, Piper nigrum, Piper retrofractum, and Piper cubeba to prove their traditional use. Methods: The level of piperin, the active compound of plants from the family Piperaceae, was also determined in the ethanolic extract of those three fruits of the pepper plant. The aphrodisiac activity was determined by counting the number of introducing and mounting mice. The acute toxicity test of the extract was carried out according to the OECD-423 guidelines. Results: The ethanolic extract of Piper nigrum fruits had the highest piperin concentration, while the ethanolic extract of Piper retrofractum fruits had the highest aphrodisiac activity, according to the findings. During the entire duration of the acute toxicity study, no signs of toxicity or mortality were discovered.Conclusion: This study proves that all fruits of three species of pepper plants exhibit aphrodisiac activity. Furthermore, this study also shows that not only piperin is responsible for the aphrodisiac effect.

Wheat is one of the world's most abundant and essential food crops. It covers a significant area of the earth's surface, higher than any other plant, and tends to be among the top strategic crops. Wheat contamination with fungi leads to rapid deterioration of quantity and quality of wheat products. Many of those fungi are potential mycotoxins producers. This study aimed to isolate and identify fungi that contaminating the wheat grains from the Misurata Agricultural Research Center area and the South Region of Libya. Fungi contaminating wheat grains were isolated on Potato Dextrose Agar (PDA) and identified by culture characteristics and microscopically. Fungal filtrates of two fungal isolates, Aspergillus niger and Rhizopus sp., were tested for their effects on the germination and seedlings of wheat grains. Furthermore, the effect of acetonic extracts of Black pepper (Piper nigrum) on the growth of the isolated fungi was also investigated. Ten types of fungi belonging to four genera were isolated and identified. The germination rate of wheat grains irrigated with the filtrate of A. niger and Rhizopus sp. was 20% and 80% respectively, compared with 100% of the control grains, which were irrigated with water. The culture filtrates of both A. niger and Rhizopus sp. affect not the only percentage of grains germination but also the morphology of wheat seedlings. It adversely affected the length of the radicles and coleoptiles. The acetone extract of P. nigrum showed inhibitory effect (85.7% ± 3.7 and 44.0% ± 3.1) on the germination of A. niger and Rhizopus sp. respectively. This study concludes that fungal secretions have pathogenic effects on plant growth, which can lead to potential health risks for the human population. Biological control such as Piper nigrum extracts can be an alternative to chemical pesticides for controlling fungal pathogens and their secretions.
