In Venezuela, Olla timberlakei Vandenberg, 1992 has been watched predating nymphs of Psyllidae associated to Platymiscium diadelphum S.F. Blake. This research was made to identify the psyllid and to determine predator's biology. Insects were collected on oak's tree in Tarabana (500 m, Palavecino) and Barquisimeto (500 m, Iribarren) Lara state, Venezuela. The biology of O. timberlakei was determined in laboratory. The psyllid belongs to the genus Platycorypha Tuthill, 1945. The life cycle of predator was 11.47±0.65 days, with duration of egg, larvae and pupa of 2.56±0.32, 8.53±0.59 and 2.94±0.18 days, respectively. The female's longevity was 44.50±13.71 days, with daily oviposition of 14.76±3.05 egg with 82.80±5.39% of viability. [ABSTRACT FROM AUTHOR]

Chilocorus nigrita Fabricius, 1798 (Coleoptera: Coccinellidae) is a predator of Hemiptera species of the families Diaspididae, Coccidae and Asterolecaniidae, with the ability to colonize a wide range of tropical and subtropical environments. It is originally from India and is distributed in other parts of Asia, Africa, Brazil and Colombia. The present study was carried out with the objective of registering for the first time the presence of the coccinellid Ch. nigrita in Lara State, Venezuela. We observed the presence of larvae and adults of the coccinellid Ch. nigrita feeding on scales (Hemiptera: Diaspididae) on plants of Washingtonia H.Wendl in the garden of a residential complex in the town of Cabudare, Palavecino municipality, Lara State, Venezuela. This is the first report of the presence of Ch. nigrita for the country, contributing to increase the knowledge on its geographic distribution in South America. [ABSTRACT FROM AUTHOR]

A predator insect larvae and eggs of Musca domestica L. (housefly) reported in the municipality Passenger Aguada, Cienfuegos. The present investigation was carried out with the objective to evaluate some aspects of the ecology and the biology of Asyndetus sp. as effective biorregulator on the populations of domestic fly in Agricultural units. It was determined the duration and the dimensions of the development states: egg, larva, pustule and adult of the insect, where 100 individuals were evaluated, as well as, the influence on the environmental conditions on the populations of Asyndetus sp. the bioregulator action of the development the populations of domestic fly in their natural media and the flight capacity of the adults of the predator. The results reveal that Asyndetus sp. carries out the predator action on the larva states and adult. The results reveal that Asyndetus sp. performs the depredations in the states larval and adult fly with a duration of 7 and 17 days for larval and adult states, respectively. The biorregulator activity is effective, so, it constitutes an efficient and stable depredator reaching up to 11 predators for prey relationships. The establishment of Asyndetus sp. allowed save for the elaboration center "The Galleon" 3600 CUC annually for no use of chemical control for the domestic fly, helping the protection to the environment and the health of the workers of the unit.

Choristoneura rosaceana (Harris) is an emerging pest of apple Malus domestica Borkh., in Mexico. Its control depends mainly on the use of chemical insecticides; however, there are reports of natural enemies of this pest that exert a considerable control. The main objective of study was to evaluate the predatory capacity by Podisus maculiventris (Say) on C. rosaceana larvae. Twelve hundred larvae of C. rosaceana were collected in apple orchards. Moreover, 87 specimens of P. maculiventris Say of different nymphal instars were collected, of which 75 specimens were collected in apple orchards and 17 in com crops, and 22 egg groups (17 in com crops and five in apple trees). Podisus maculiventris consumption bioassays were performed over C. rosaceana larvae, where average was 0.72 larvae consumed per day, first nymphal instar showed a higher average (1.9 larvae per day) in first 24 h, and second nymphal instar showed a higher average after 7 d (1.2 larvae consumed per day).

The biology of Chilocorus cacti Linnaeus, 1767 as predator of cochineal pest (Dactylopius opuntiae (Cockerell)) of cactus vegetable in Milpa Alta, D.F was studied. The experiment was carried out in a breeding chamber, under a temperature of 25 ±2°C, 45% relative humidity and photoperiod of 16 h of light and 8 h of darkness. The life cycle of the predator lasted 89 days, whit the following stages: egg 9 days; larva 29 days; pupa 8 days and adult has 40 days. There was no cannibalism among adults, although larvae cannibalized larvae and eggs and adults cannibalized eggs. [ABSTRACT FROM AUTHOR]

Acalanthis quadrisignata Erichson (Coleoptera: Trogossitidae) is an endemic beetle predator of southern Chile and Argentina, inhabiting native forest environments. By conducting a study on the life cycle of the small banded pine weevil, Pissodes castaneus De Geer, using trap logs and sampling forest debries, in a Pinus radiata (D. Don) afforestation in Trevelin (Chubut, Argentina), between September 2014 and September 2015, adults of A. quadrisignata were found inside the pupal chambers of the weevil. This is the first record of a natural enemy of P. castaneus in Patagonia, Argentina. This contribution adds a new habitat record where A. quadrisignata can develop and a new record to its geographical distribution in Argentina. [ABSTRACT FROM AUTHOR]

Bactericera cockerelli (Sulc) (Homoptera: Psyllidae) is an important pest of solanaceous in Mexico, for its control the use of pesticides is the main method. Reason why the use of natural enemies under an integrated management system, has been little used, as in the case of Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae), reported biological control agent for this pest, however lack studies to determine their control potential. Therefore, the objective of this study was to determine the type and parameters of functional response of C. carnea on nymphs of B. cockerelli. The logistic regression analysis revealed that the functional response of the three larval instars of C. carnea on nymphs of B. cockerelli was type II. The three instars consumed nymphs of B. cockerelli, however the third instar had higher consumption, shorter handling and greater coefficient of attack, these results demonstrated that C. carnea was voracious and predatory capacity is a function of their state of development, the third instar revealed high potential to reduce pest populations, suggesting that can be included in systems integrated pest management based augmentative biological control.

By means of the usage of Lindgren traps laced with frontaline and other baits, placed on 12 different temperate forest climate localities throughout Mexico, there were obtained six species of the genus Enoclerus (Coleoptera: Cleridae: Clerinae), A general diagnosis and key for these species is presented. The members of this genus are very important natural predators of bark and ambrosia beetles. A genus-level integrated analysis is presented for each of the capturing sites. The analysis involved all captured insects. Prominent among the captured beetles were E. ablusus, E. arachnodes, E erro due to its abundance and the number of localities on which those were present, whereas E. aethiops, E. moestus and E. nigricans are sparsely represented, both in number and collected localities. New distributional records are reported for all the collected species. [ABSTRACT FROM AUTHOR]

Diatraea saccharalis (Fabr.) is considered the key pest of sugarcane crops in the Argentine northwest. The earwig Doru luteipes (Scudder) develops high populations on sugarcane, and in other regions it was depicted as a significant predator of diverse pest in corn, cotton, and cabbage crops. The aim of this contribution is to inform about different biological parameters of this Dermaptera, and to assess the predatory capacity of its nymphs by means of the estimation of consumption rates using Diatraea saccharalis eggs. Both field and laboratory observations were carried out. In the latter, 50 neonate nymphs were confined in glass tubes and 100 sugarcane borer eggs were provided daily. Information on different behavioral aspects is provided. In field conditions, the sex proportion is approximately 1:1; an average of 31 eggs were laid, and the emergence rate reached 95%. Egg incubation is complete within a range of 6-10 days, and pre-imaginal development has a mean duration of 37.6 days. Throughout the four nymphal instars, a single individual could consume an average of 591.3 sugarcane borer eggs. The potential implication of the given information in applied sugarcane borer control methodologies is discussed. [ABSTRACT FROM AUTHOR]
