Engytatus varians (Distant) (Hemiptera: Miridae) is a zoophytophagous species that feed on plants as well as of the phytophagous insects living on them such as aphids, whiteflies, pseudococcids, and lepidopterans. Currently, this species has a wide but not precise distribution. In this work is reported for first time the presence of E. varians in Mexico and the predation on nymphs of tomato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae) under greenhouse conditions. A fourth instar of E. varians fed 46% of third instar of B. cockerelli in a period of 24 h. This result showed that this predator could be a promising agent for management for tomato psyllid. Data of its distribution, host plants, and preys are also included. [ABSTRACT FROM AUTHOR]

Apanteles nr. Aristoteliae (Viereck) (Hymenoptera: Braconidae) is an endoparasitoid of the leafroller Amorbia sp. (Lepdidoptera: Tortricidae) larvae. In this study, the life cycle, parasitism, sex ratio, and longevity of adults of this parasitoid were determined under laboratory conditions (22 ± 2 °C, 60 ± 5% relative humidity, and a photoperiod of 16:8h [light:dark]). The life cycle of this parasitoid was 42.45 ± 0.76 days. The duration of development stages of egg-larva, pupa and adult was 14.04 ± 0.05, 9.22 ± 0.07, and 19.36 ± 0.74 days, respectively. Each A. nr. aristoteliae female parasitized 73.33 ± 7.55 Amorbia sp. larvae. The sex ratio of FI generation was 95.1% males (n = 912). Longevity of adults was significantly different (U = 564, P = 0.01) between mated males (27 ± 2.55 days) and virgins (19.75 ± 0.70 days) but not (U = 182, P = 0.3) between mated females that were exposed to parasitization during all its life (26.4 ± 2.88 days), and virgins (23.13 ± 1.4 days). In order to obtain a better understanding about life parameters of A. nr. aristoteliae, future studies that include different rearing conditions (e.g., temperature and space) are needed.
