Effects of different culture media and conditions on biomass production of hairy root cultures in six Mexican cactus species
TLDR
The results showed that medium optimization needs to be performed for each individual species, as growth responses differed among taxa, and culture medium was found to affect hairy root morphology of all species tested.
PATHOGENICITY OF BEAUVERIA BASSIANA (DEUTEROMYCOTA: HYPHOMYCETES) AGAINST THE CACTUS WEEVIL, METAMASIUS SPINOLAE (COLEOPTERA: CURCULIONIDAE) UNDER LABORATORY CONDITIONS
TLDR
Results indicate for the first time the possible use of B. bassiana as biocontrol agent against this insect pest M. spinolae, an important pest of cactus plants.
Fruit Damage Patterns Caused by Ovipositing Females of Conotrachelus dimidiatus (Coleoptera: Curculionidae) in Guava Trees
TLDR
The information from this study will be used to design and establish effective control strategies for the guava weevil, taking into account location of the most susceptible fruits, seasonality of the pest, and the abiotic factors.
Aggregation Pheromone of Metamasius spinolae (Coleoptera: Curculionidae): Chemical Analysis and Field Test
TLDR
Preliminary field experiments showed that significantly more adult cactus weevils were caught in traps baited with the major single compound three or the 2 + 3 binary combination than in unbaited control traps, however, highest trap efficacy occurred with the 1 + 2 binary combination and a blend of all three synthetic compounds plus prickly pear.
Evidence of an Aggregation Pheromone in Males of Metamasius spinolae (Coleoptera: Curculionidae)
TLDR
This study is the first report of such a pheromone system for this tropical species, and attraction responses in laboratory and field studies suggest that a male-produced aggregation phersomone is the prevalent mechanism of chemical communication among cactus weevils.
Paclobutrazol Applied on Cotyledonal Leaves and Quality of Cucumber, Squash, Melon and Watermelon Seedlings
TLDR
In the four species (cucumber, squash, melon and watermelon), the PBZ increased the chlorophyll content in 26.0%, 14.9%, 19.4% and 26.5%, respectively, compared to the control, so that the 150 mg dose of PBZ can be used to produce seedlings with higher quality for transplant.
Sunlight transmitted by colored shade nets on photosynthesis and yield of cucumber
TLDR
Pearl, red, aluminized and blue nets showed to be viable alternatives because the production of fruit increased in 71, 48, 46 and 46%, respectively, in comparison with the conventional black net (52t ha-1).
Efecto in vitro de fosfito de potasio sobre "Athelia rolfsii" y "Pythium aphanidermatum"
The objective of this study was to determine the in vitro effect of potassium phosphite on the radial growth of the mycelium, the production of biomass and the production of sclerotia of Athelia
Behavioral and Electroantennographic Responses of Adults of Guava Weevil, Conotrachelus dimidiatus (Coleoptera: Curculionidae), to Synthetic Host-Associated and Conspecific Volatiles.
TLDR
This study assesses the behavioral and electrophysiological responses of the weevil to selected semiochemicals emitted by the host plant fruit and to conspecifics and indicates that synthetic compounds from host plant volatiles and insect volatile pheromones produce olfactometry and electroantennographic responses in C. dimidiatus.
Dose of Paclobutrazol in the Growth of Sugarcane Seedlings in Vitro in the Acclimatization Stage
TLDR
The results of the study indicated that the dose of 150 g·L-1 of PBZ induced the growth of plants more compact and of better quality for the transplant.
