one of the most important predator-prey interactions is functional response which its type and parameters are affected by different factors including host plant characteristics. in this research, the influence of leaf surface on functional response and prey consumption rate of third instar larvae of the episyrphus balteatus (de geer, 1776) (diptera: syrphidae) to third instar nymphs of aphis go...

Abstract. This paper describes recognition and cutting system of sweet peppers for picking robots in greenhouse horticulture. This picking robot has an image processing system with a positioning system for two cameras and cutting a device to follow the sweet pepper by visual feedback control. A prototype robot system is introduced. Experiments of the prototype robot prove the performance of the...

We report for the first time conical galls of Clinodiplosis capsici Gagné, 2000 (Diptera, Cecidomyiidae) on sweet pepper ( Capsicum annuum L., Solanaceae) in Brazil. This has agricultural importance since this midge is one known sweet-pepper pests.

This paper describes development and experiments of a picking robot for sweet peppers in greenhouse horticulture. This picking robot has an image processing system with a parallel stereovision, a camera positioning system to follow the sweet pepper by visual feedback control, and a cutting device. A prototype robot system has been made and is introduced. Experiments of the prototype prove that ...

Root-knot nematodes of the genus Meloidogyne are important pathogens affecting vegetable crop production in Brazil and worldwide. The pepper species Capsicum annuum includes both hot and sweet peppers; very little emphasis has been placed on breeding sweet peppers for nematode resistance. We report on the inheritance of resistance to Meloidogyne incognita (Kofoid & White) Chitwood race 2 in the...

objectives: sweet peppers capsicum annuum l. (c. annuum) are an excellent source of vitamins a and c as well as phenolic compounds, which are important antioxidant components that may reduce the risk of diseases. the objective of this study was to evaluate their antioxidant activity under various temperatures. materials and methods: to compare the antioxidant activity in various temperatures (2...

It can by using organic and bio-fertilizer minimize vegetables plants requirements from inorganic synthetic fertilizers which are potentially more detrimental to the environment. The objective of this work was to study the response of sweet pepper plants cv. California Wonder to some micro-organisms and organic fertilizer by soil inoculation with different rats of compost tea (10 or 20 L/fed.) ...

The potentials of poultry, farmyard and refuse dump manures for management of Phytophthora root rot on sweet peppers, Capsicum annuum was evaluated in pot experiments under controlled conditions. Five week-old seedlings of pepper varieties were transplanted into heat sterilized soil amended with poultry, farmyard and refuse dump manures at 2, 4 and 8 tons/ha. The pots were arranged in complete ...
