The impact of commonly used organophosphate (chlorpyrifos, methamidophos), carbamate (carbaryl), and pyrethroid (cypermethrin) insecticides on insect natural enemies was compared with that a nucleopolyhedrovirus (Baculoviridae) Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) in maize grown southern Mexico. Analyses the SELECTV Koppert Side Effects (IOBC) databases synthetic arthropod were to predict ≈75–90% enemy mortality after application, whereas bioinsecticide predicted have...
Flaming can be an effective nonselective, nonchemical method of weed control. It has been more against broadleaf weeds than grasses. Experiments were conducted with a conveyor bench burner apparatus to evaluate flaming kill and grass seedlings at the 0- 2- 4-leaf stages. Most 2-leaf green foxtail killed when flamed 2, 4, 6 km/h speed. A few plants survived 8 km/h. Green stage tolerant foxtail, substantial numbers all speeds except 2 Barnyardgrass was many after flaming. However, fresh weight...
A pilot study performed on the Pacific coastal plain of Chiapas, Mexico, focused prevalence maize crop infestation by insect pests, parasitism pests and abundance predators in plots with weeds compared under a regime rigorous manual weed control. Sampling was conducted four occasions at 20, 32, 44 56 days post-planting. Infestation fall armyworm larvae, Spodoptera frugiperda (Lepidoptera: Noctuidae), more than twice as great strict control weedy 20 post-planting, but declined thereafter both...
To determine the insecticide resistance status of Ae. aegypti and albopictus from Tapachula, México.Mosquito eggs were collected with use ovitraps CDC susceptibility bioassays biochemical assays conducted to levels mechanisms, respectively.Ae. showed deltamethrin permethrin (PYRs), malathion, chlorpyrifos temephos (OP), bendiocarb (CARB), while malathion a lesser intensity chlorypirifos, temephos, deltamethrin. Both species high P450 GSTs, esterases varied by collection site. Altered...
Laboratory studies were performed on the lethal and sublethal effects of spinosad three important species parasitoids attacking Spodoptera frugiperda (J.E. Smith) in Mexico. Reproduction braconid Chelonus insularis (Cresson), treated egg masses was completely eliminated at 200 parts per million (ppm) reduced by ∼70% 20 ppm compared to controls. Adult C. did not avoid contact with residues maize (200 ppm), but suffered a 7-day reduction longevity after residues. Initial toxicity applied...
Abstract The behaviour of two abundant predators in Mesoamerican maize crops, Chrysoperla rufilabris larvae and Doru taeniatum adults, towards healthy nucleopolyhedrovirus‐infected Spodoptera frugiperda was compared. C. did not discriminate between virus‐infected prey, although the mean search time approximately times longer larvae. In contrast, D. directed a greater proportion their attacks prey but there no significant difference time. Prey consumption differ significantly for each type by...
Field trails in 2002 and 2003 were performed to determine the efficacy of maize flour-based granular formulations with ultralow rates naturally derived insecticide spinosad (0.1, 0.3, 1.0 g [AI]/ha), for control Spodoptera frugiperda (J.E. Smith) maize, Zea mays L., southern Mexico. Spinosad compared a chemical standard, commercial formulation chlorpyrifos (150 [AI]/ha). In both years, application resulted excellent levels control, indicated by number living S. larvae recovered from...
Rambutan is an important cash crop in the Mexican State of Chiapas. In last few years this has been expanded to other agricultural areas Mexico, and mealybugs (Hemiptera: Pseudococcidae) represent a potential phytosanitary risk for crop. The present study was performed with objectives identify mealybug species associated rambutan, determine their altitudinal distribution Soconusco region A total six orchards were sampled mealybugs, two at each level: low zone, i.e., 60–70 meters above sea...
is an endoparasitic nematode of the coffee berry borer
Metaparasitylenchus hypothenemi is an endoparasitic nematode that causes partial or total sterility of coffee berry borer (Hypothenemus hampei) females, although the are unknown. Fecundity and average size common lateral oviduct, vitellarium, germarium in four ovarioles (I, II, III IV) were compared between parasitised non-parasitised insects to determine sterility. The significantly lowers number oocytes 86% (24 out 28 insects) sterile, while fecundity remaining 13% was non-significantly...
Background: There is no previous evidence in the literature that documents presence of extrafloral nectaries (EFNs) or exomorphology domatia Nephelium lappaceum (rambutan), a fruit tree native to Malaysia introduced various American countries.
 Question: It EFNs responsible for frequent visit ants young leaves lappaceum?
 Study site and dates: This study was conducted commercial rambutan orchard town Francisco I. Madero, municipality Frontera Hidalgo (Chiapas, Mexico) during period...
Parasitism by Cirrhencyrtus spp. on Ferrisia virgata Cock and Dysmicoccus brevipes Cockerell associated with rambutan (Nephelium lappaceum L.) crops in Mexico was reported. Parasitoids were randomly sampled six commercial orchards where synthetic insecticide not applied. aeoles (Noyes), silvia pertius (Noyes) recorded 15 samples at four localities from 504 collected localities. This is the first record of these parasitoids new host associations.
We analysed the impact of Anagyrus kamali on survival and development Ferrisia virgata, three stages (second third-instar nymphs, adult females) five densities (1, 2, 4, 8 16), using same treatments in absence parasitoid as a control. In each assay, female was confined with F. virgata for 14 ± 0.9 days. A. females can reduce inhibiting its development. Emergence progeny inhibited developmental due to high mortality immature kamali.
