Potato (Solanum tuberosum) is the fourth most important crop in terms of production in Pakistan. Potato reveals a portion of 42 kilograms per person each of the yearly diet plans in some nations (FAO, 2010). It is attacked by various pests including aphids, Abstract | The efficacy of botanical insecticides i.e. Neem and Black pepper were evaluated against the insect pests (whitefly and aphid).The methanolic extracts of Black pepper and Neem were analyzed for identification of phytochemicals by using Gas Chromatography-Mass Spectrometry. The result showed that Alkaloids, Flavonoids, Tannins, Terpenoids and Phenolic compounds were found both in Black pepper and Neem.Quantitative analysis indicated 21 active componentsin Black pepper which were dominated byCaryophyllene (32.3%), Delta-3-carene (18.7%) and Cinene(15.5%). Neem showed 17 active components, among them Beta-Pinene (14.8%), Delta-Elemene (14.4%) and Palmitic acid (13.2%) were dominant. The mix-biopesticide of Black pepper and Neem in comparison to their individual impact showed the highest insecticidal efficacy against whitefly and aphids. The plots sprayed with mix-biopesticide showed the highest yield of okra and potato crops along with a healthier plant growth. The highest yield of Okra (52 kg) and Potato (272 kg)and their plant growth was recorded in plots sprayed with mix-biopesticides. It is concluded that biopesticide from these two plants could be utilized for their efficacy against various pests of okra and potato. Keeping the environmentally friendly nature of these biopesticide, compared to synthetic pesticides, it is recommended that more research be directed for assessment of more active compounds that could act as potential candidates for biopesticide. The objective of the study was to find the bioactive compounds in plant extracts of Neem and Black pepper and their effectiveness against reduction in number of whitefly and aphids.

Tropical Plant Species and Technological Interventions for Improvement

The tropical climate shift is causing herbivores to emerge almost ceaselessly throughout the year in certain regions exhibiting homodynamic cycles and unbalanced biodiversity. Crop management and pest management are being viewed as separate activities, with recent focus on sustainability. Even though there is a great deal of information on crop loss assessment, systems analysis, systems modelling, individual pest sciences, and pest management, the Integrated Pest Management (IPM) concept is not frequently deployed. The IPM system is a multi-tactic approach to pest management in agricultural production that takes into account economic, environmental, ecological, and human health implications. This paper provides an overview of key achievements in the development of management strategies, including the transition from a specific level of pest control that focuses on the suppression of target pests to an eco-friendlier and/or systems approach to pest management that employs a variety of non-chemical options as well as the judicious use of pesticides. The agroecological protection techniques and their integration to sustainably minimise pest risks are also reviewed here and describe technological advances in tropical pest management using host resistance, semiochemicals, natural enemies, selective pesticides, ecological engineering and habitat management which promotes sustainable pest management.

“…The honeydew excreted by B. tabaci provides a medium for the growth of sooty mold on the leaves and fruits, thus reducing photosynthetic activities, which could negatively affect the quality of farm produce [ 1 , 39 ]. In addition, the feeding of B. tabaci on leaves can cause yellowing and crumpling, which subsequently results in stunted plant growth and deformed fruits [ 3 ].…”

“…Of the 1556 species of whiteflies recorded in the world, B. tabaci remains one of the most economically important pests of vegetable and ornamental crops worldwide [ 1 , 2 ]. The insect feeds on several solanaceous and ornamental crops, including brinjal, chili, cotton, okra, potato, tomato, and tobacco [ 3 , 4 ]. The economic damage caused by B. tabaci ranges from mild to catastrophic with global annual loss reaching up to billions of USD in many crops [ 5 , 6 , 7 ].…”

Whitefly, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), consists of genetically diverse species known to cause significant destruction in several crops around the world. Nymphs and adults of B. tabaci cause damage to plants during feeding, and they can act as a virus vector, thus causing significant yield loss to crops in the tropical and subtropical regions. Chemical pesticides are widely used to control B. tabaci due to their immediate action, but this approach has several drawbacks including food safety issues, insecticide resistance, environmental pollution, and the effect on non-target organisms. A biological control agent using entomopathogenic fungi (EPF) has therefore been developed as an alternative against the conventional use of chemical pesticides in an integrated pest management (IPM) system to effectively control B. tabaci. It is apparent from this review that species of hyphomycetes fungi are the most common EPF used to effectively control B. tabaci, with the second instar being the most susceptible stage of infection. Therefore, this review article focuses specifically on the control of B. tabaci with special emphasis on the use of EPF as biological control agents and their integration in IPM.
