Abstract:
Infestation of major pests and diseases on various cassava clones in Lampung-Indonesia. Lampung Province is one ofcassava producers in Indonesia which contributes more than 30% to the total national cassava production. However, theinfestation of pests and diseases can limit cassava production in the field. The objective of this research was to observe theinfestation level of major plant pests and diseases of cassava in Lampung. A survey was conducted in August 2016 in severallocations of cassava fields owned by farmers and experimental plots in the area of Faculty of Agriculture, University of

The TFRUIT·Xpert and CIT·Xpert computerbased diagnostic programs can quickly assist commercial producers, extension agents, and homeowners in the diagnosis of diseases, insect pest problems and physiological disorders. The CIT·Xpert system focuses on citrus (Citrus spp.), whereas the TFRUIT·Xpert system focuses on avocado (Persea americana Mill.), carambola (Averrhoa carambola L.), lychee (Litchi chinensis Sonn.), mango (Mangifera indica L.), papaya (Carica papaya L.), and `Tahiti' lime (Citrus latifolia Tan.).

Profit loss is a phenomenon caused by the loss of most of the harvest resulting in operating costs greater than the revenue earned. This phenomenon deserves to be analyzed the risk of losses that will be obtained due to pests and plant diseases. So that in this study an analysis of the risk of Profit loss due to yellow mosaic disease on papaya calina was carried out. This research was conducted in October 2020 in Bengkulu Province on 31 Calina Papaya farmers. The location selection was carried out purposively based on the existence of the Calina papaya garden.

Abstract:
The papaya (Carica papaya L.) is an economically important crop in Mexico and Latin America. The nursery phase plays a primary role in the production process, at this stage, it is susceptible to pests and diseases. The use of biofertilizers based on entomopathogenic fungi (EF) is an alternative to produce healthy and quality seedlings, through biological agriculture. The objective was to evaluate the ability of Beauveria brongniartii and Purpureocilium lilacinum to colonize tissues, promote emergence and improve the plant quality of two papaya genotypes in nursery.

A computer-based diagnostic system that can assist commercial producers, extension agents, and homeowners in the diagnosis of diseases, disorders, and pest damage for citrus, avocado, `Tahiti' lime, mango, carambola, lychee, and papaya was developed. The program was written in C++ and runs under MS-DOS. The system design was based on the diagnostic reasoning process of experts by identifying the location of symptoms, tree vigor, and occurrence within a grove. Full-screen color images link symptoms to possible diseases, disorders, and/or pest damage. Users can also refer to expert knowledge, gr

Abstract:
The world is faced with a lot of challenges including lack of sustainable development and inability to feed its growing population leading to malnutrition. The issue of accessing high quality nutritious foods such as fruits has become a major challenge for many African people. Papaya (Carica papaya L.) is among the most popular fruits grown in Kenya and excellent in nutritional content. However, its potential has remained unexploited due to inadequate quality planting materials, high post- harvest losses and prevalence of pests and diseases.

Although Kenya has a well-developed phytosanitary system to regulate introduction of plant and plant products, several pest incursions have been reported in the last two decades. The incursions have culminated in devastating impact on agriculture, biodiversity and the entire Kenyan economy. The objective of this review is to consolidate information on the pests involved, their distribution, estimate the economic losses associated with them and management measures in place.

Abstract:
One of the problems in papaya cultivation is the high attack of pests and diseases. The mealybug, P. marginatus L (Hemiptera: Pseudococcidae) is currently found to attack papaya plants. The infestation of mealybugs greatly affects the yield and quality of fruits. The purpose of this study was to determine the effect of the concentration of citronella oil on mealybugs on papaya plants. The study for the observation of mortality and fecundity used a Randomized Block Design (RAK), with 4 treatment levels of citronella oil concentration, namely 0 (control), 0.5 mL/L, 1 mL/L and 2 mL/L.
